1.	Ahmed, Lamis, et al. (författare) Dynamic Measurements for Determining Poisson’s Ratio of Young Concrete 2018 Ingår i: Nordic Concrete Research. - 0800-6377. ; :58, s. 95-105 Tidskriftsartikel (refereegranskat)abstract Knowledge of the elastic properties of concrete at early age is often a pre-requisite for numerical calculations. This paper discusses the use of a laboratory technique for determining Poisson’s ratio at early concrete age. A non-destructive test set-up using the impact resonance method has been tested and evaluated. With the method, it has been possible to obtain results already at 7 hours of concrete age. Poisson's ratio is found to decrease sharply during the first 24 hours to reach a value of 0.08 and then increase to approximately 0.15 after seven days.

(författare) Continuous Preventive Bridge Maintenance of Swedish Municipalities : A Survey on Common Practice 2018 Ingår i: Nordic Concrete Research. - Oslo : Walter de Gruyter GmbH. - 2545-2819 .- 0800-6377. ; 58 Tidskriftsartikel (refereegranskat)abstract As part of a report [1] on continuous preventive bridge maintenance, a survey was conducted with Swedish municipalities. The survey’s focus was on bridges and preventive maintenance, as well as the demands and performance control stated by the municipalities. The preventive maintenance the survey focused on was the annual maintenance concerning washing, cleaning of drainage system and removal of vegetation. The survey showed both similarities and differences within the municipalities but also in comparison with Swedish Transport Agency (STA).

(författare) Corrosion-induced cracking and bond behaviour of corroding reinforcement bars in SFRC 2017 Ingår i: Nordic Concrete Research. - 0800-6377. - 9788282080569 ; , s. 123-126 Konferensbidrag (refereegranskat)abstract In this study, an experimental programme has been carried out to investigate the influence of fibres on the onset of corrosion-induced splitting cracks. Cylindrical lollipop specimens with a centrally positioned Ø16 mm bar and varying cover depths from 40 to 64 mm were subjected to accelerated corrosion. A constant current of 100 μA/cm2 was impressed through the specimens and the electrical resistance between each rebar and an external copper mesh acting as cathode was monitored. The fibres, due to their confining effect, contributed to delay crack initiation, improve the post-peak bond behaviour and retain the initial splitting strength for corrosion levels of up to 8%.
4.	Cyron, Wojciech, et al. (författare) Bonded Concrete Overlays: A Brief Discussion on Restrained Shrinkage Deformations and Their Prediction Models 2019 Ingår i: Nordic Concrete Research. - : Walter de Gruyter. - 0800-6377 .- 2545-2819. ; 61:2, s. 107-129 Tidskriftsartikel (refereegranskat)abstract Bonded concrete overlays (BCO) on bridge decks are beneficial solutions due to their superior properties as compared to the typical asphalt pavement. A significant number of overlays suffer however, from occurrence of cracks and delamination due to poor bond, and restrained shrinkage and thermal dilation. Over the past years different appraisals for estimation of the restrained deformations have been developed, from micro-scale models, based on poromechanics, to empirical equations as given in B3 or B4 models suggested by Baiant. This paper provides a short overview of calculation models along with a brief theoretical explanation of shrinkage mechanism.

(författare) Rice Husk Resource for Energy and Cementitious Products with Low CO2 contributions 2018 Ingår i: Nordic Concrete Research. - : Walter de Gruyter GmbH. - 0800-6377 .- 2545-2819. ; 59:2, s. 45-58 Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract Rice Husk Ash (RHA) is a well-known supplementary cementitious materials (SCMs) that can be used for concrete with reduced CO2 contributions. In 2016, only Nepal produced 5.2 million tonnes rice that gave about 1.14 million tonnes rice husk. The rice husk can also be used directly in a cement kiln as a fuel. This study analysis the potential CO2 reductions from three scenarios and emphasis strengths, weaknesses, opportunities and treats in the production systems for initiate a decision process with possibilities to get an industry project financed from the green climate found. The highest CO2 benefits were from rice husk used in a cement kiln were half of the yearly rice husk production in Nepal could reduce the climate impact with 808000 tonnes CO2.
6.	Döse, Magnus, et al. (författare) Effect on Radon Exhalation Rate Due to Cracks in Concrete 2019 Ingår i: Nordic Concrete Research. - : NORDIC CONCRETE FEDERAT. - 0800-6377 .- 2545-2819. ; 61:2, s. 79-90 Tidskriftsartikel (refereegranskat)abstract The second largest cause of lung cancer in the World is related to radon (Rn-222) and its progenies in our environment. Building materials, such as concrete, contribute to the production of radon gas through the natural decay of U-238 from its constituents. The Swedish Cement and Concrete Research Institute (CBI), part of RISE (Research Institute of Sweden AB), has examined the effects of cracks in concrete on two different concrete recipes where an Ordinary Portland Cement, OPC-CEM-I concrete (REF) and an OPC concrete including a hydrophobic additive (ADD) were addressed. Two concrete prisms from each concrete recipe were examined. The radon exhalation rate was measured in the pristine state and after concrete cracks had been induced into the concrete prisms. Measurements were performed with an ATMOS 33 ionizing pulsation chamber. The results indicate a strong influence of cracks on the radon exhalation rate. An increase in radon exhalation rate was calculated for every test prism. The increase in radon exhalation rate varied between 80 and 260 %. The crack apertures may play a significant role on the exhalation rate. The concrete prisms with the largest apertures (ADD) also generated the highest radon exhalation rates. The results imply that there could be a substantial variation in the exhalation rate, due to numerous factors, but nonetheless, the results should, raise the awareness of the impact cracks in concrete structures, may have on the final exhalation rate of radon. The exhalation rate of the recipe with an additive (ADD) also showed a lower exhalation rate than for the reference recipe (REF), when compared in a pristine state. This was in part expected. However, the effect of induced cracks and its aperture, seemingly trumps the effect that an additive may play on the radon exhalation rate, when cracks are induced.The hypothesis is in part verified in view of the results of the prism for the ordinary Portland recipe (REF-prisms), were an increase of approximately 100 % would be expected due to the total surface increase. The results also indicate this. The major increase in the radon exhalation rate of the ordinary Portland recipe including an additive, implies however other factors, such as minor internal cracks, that may substantially contribute to the final exhalation rate.
7.	Döse, Magnus, 1970-, et al. (författare) Reduction of Radon Gas in Concrete Using Admixtures and Additives 2018 Ingår i: Nordic Concrete Research. - Oslo. - 0800-6377. ; 58 Tidskriftsartikel (refereegranskat)abstract The second largest cause of lung cancer is related to radon (222Rn) and its progenies in our environment. Building materials, such as concrete, contribute to the production of radon gas through the natural decay of 238U from its constituents. The Swedish Cement and Concrete Research Institute (CBI) has examined three concrete recipes where only an additive as well as fly ash were added as single constituents to a reference recipe and compared to a reference concrete. The inputs of an additive as well as a supplementary cementitious material (fly ash) were made as a mean to investigate their potential influence on the radon exhalation rates of the concrete. Measurements were performed with an ATMOS 33 ionizing pulsation chamber for at least five different occasions for each recipe during a 22 month period. The results indicate a reduction of the exhalation rate by approximately 30-35 % for each altered recipe. This means roughly 1.5-2 mSv per year decrease in effective dose to a human using an additive or a supplementary cementitious material such as fly ash in relation to the investigated standard concrete.
8.	Fahimi, Shayan, et al. (författare) Replication of Crack Pattern in FE Analysis Based on Discretization of Tension Softening Curves 2017 Ingår i: Nordic Concrete Research. - 0800-6377. ; 56:1, s. 1-9 Tidskriftsartikel (refereegranskat)abstract Today, there is an increasing need for reliable methods for condition assessment and service-life evaluation of existing structures. Although advanced 3D Nonlinear Finite Element (3D NLFE) analysis has proven to be capable of describing the behavior of reinforced concrete in a comprehensive way, the analysis results are difficult to couple with visual inspection data such as cracking and spalling. Moreover, 3D NLFE programs are numerically expensive and incomprehensible for full-scale practical applications. Thus, the present study aims to couple 3D NLFE analysis with condition assessment data, and consequently to increase the accuracy, to optimize the computation time and to improve robustness of such analyses.
9.	Flansbjer, Mathias, et al. (författare) Meso Mechanical Study of Cracking Process in Concrete Subjected toTensile Loading 2018 Ingår i: Nordic Concrete Research. - Oslo : Walter de Gruyter GmbH. - 0800-6377 .- 2545-2819. ; 59:2, s. 13-29 Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract This project focused on how the cracking process in concrete is influenced by both the micro and meso structures of concrete. The aim was to increase knowledge pertaining to the effect of critical parameters on the cracking process and how this is related to the material's macroscopic properties. A methodology based on the combination of different experimental methods and measuring techniques at different scales was developed. Crack propagation during tensile loading of small-scale specimens in a tensile stage was monitored by means of Digital Image Correlation (DIC) and Acoustic Emission (AE). After testing, crack patterns were studied using fluorescence microscopy.
10.	Geiker, Mette Rica, et al. (författare) Screening of Low Clinker Binders, Compressive Strength and Chloride Ingress 2017 Ingår i: Nordic Concrete Research. - : Nordic Concrete Federation. - 0800-6377 .- 2545-2819. ; 57:2, s. 23-38 Tidskriftsartikel (refereegranskat)abstract This paper reports an initial screening of potential new binders for concrete with reduced CO2-emission. Mortars cured saturated for 90 days are compared with regard to a) compressive strength of mortars with similar water-to-binder ratio, and b) chloride ingress in similar design strength mortars exposed to seawater. The reference used was a binder composition typical for a Danish ready mixed concrete for aggressive environments and strength class C35/45. Based on the present investigation and assumptions up to around 15% reduction in CO2 emission from binder production might be obtained without compromising the 90 days compressive strength and resistance to chloride ingress in marine exposure by using selected alternative binders.
11.	Jansson, Helen, 1964, et al. (författare) Carbonation of concrete with mineral additions 2017 Ingår i: Nordic Concrete Research. - 0800-6377. - 9788282080569 ; , s. 101-104 Konferensbidrag (refereegranskat)abstract This study investigated how mineral addition, fly ash and slag (GGBS), influences carbonation, and how carbonation affects chloride migration and transport properties in mortar. Accelerated carbonation, Rapid Chloride Migration (RCM), capillary absorption tests (NT Build 368) and compressive strength tests (SS-EN 196-1) were conducted in a comparative study of mortar mixtures with different levels of mineral addition and w/b ratios. Carbonation rate increased and compressive strength was reduced with increased amount of mineral addition. The results also showed an interdependence between different deteriorating processes. Carbonation reduced the porosity, rate of reaching saturation and connectivity of the pore structure.
12.	Jansson, Helen, 1964, et al. (författare) Parameters influencing the initial setting time of alkali-activated ground granulated blastfurnace slag materials 2015 Ingår i: Nordic Concrete Research. - 0800-6377. ; 52, s. 63-76 Tidskriftsartikel (refereegranskat)abstract Various parameters influencing the initial setting time of alkali-activated slag materials have been investigated using the Vicat method. The alkali solutions used for the activation were liquid sodium silicate (water glass) of different moduli n (SiO2/Na2O ratio) and pH. The results indicate that the initial setting time is mainly influenced by two parameters; 1) the specific surface area of the slag and 2) the modulus of the solution. The results also suggest that the problem with controlling the initial setting time of alkali-activated slag can be solved by controlling the characteristics of the solvent used for the activation.

(författare) Topological and Size Optimization of RC Beam Bridges : An Automated Design Approach for Cost Effective and Environmental Friendly Solutions 2019 Ingår i: Nordic Concrete Research. - : Walter de Gruyter GmbH. - 0800-6377 .- 2545-2819. ; 61:2, s. 53-78 Tidskriftsartikel (refereegranskat)abstract This work presents a procedure for the automated design and optimization of reinforced concrete beam bridges. The aim is to find solutions that minimize the investment cost and the environmental impact of the bridge. The complete structure is optimized including: number of spans, pier locations, pier-deck connections and deck dimensions. A detailed design of the deck reinforcement is included as well. Furthermore, constructability is considered and quantified within the investment cost to avoid a merely theoretical optimization. Genetic Algorithm (GA) and Pattern Search (PS) optimization algorithms are used. To reduce the computational time and make the procedure more user-friendly, a memory system is integrated and a modified version of GA is developed. In this paper, the proposed procedure is applied to re-design an existing bridge originally designed according to Eurocodes by an experienced engineer in 2013. Savings of 1015% for both investment cost and environmental impact have been obtained. Finally, the proposed procedure has been applied to several alternatives with different total bridge lengths to suggest the optimal number of spans for a given total bridge length.
14.	Lövgren, Ingemar, 1972 (författare) The influence of carbonation and age on salt frost scaling of concrete with mineral additions 2017 Ingår i: Nordic Concrete Research. - 0800-6377. - 9788282080569 ; , s. 141-144 Konferensbidrag (refereegranskat)abstract Resistance to salt frost scaling is tested by accelerated methods such as CEN/TS 12390-9. However, it has been shown that ageing and coupled deterioration mechanisms, like carbonation or leaching, can alter the frost resistance e.g. for concrete with high amount of slag (GGBS). This paper presents results from a laboratory study of concrete which have been exposed to accelerated carbonation at 1% CO2-concentration at different ages. The results show that exposing the specimens to accelerated carbonation at a young age result in an increased scaling and a carbonation depth corresponding to 10 year natural exposure. By increasing the age before the accelerated carbonation exposure the scaling is significantly reduced and the salt frost scaling resistance correlates better with field observations.

Malm, Richard, 1980- (författare) Full-scale test of an unreinforced concrete dome plug for the spent nuclear fuel repository 2018 Ingår i: Nordic Concrete Research. - : The Nordic Concrete Federation. - 0800-6377 .- 2545-2819. ; 58:1, s. 55-75 Tidskriftsartikel (refereegranskat)abstract In the planned Swedish repository for spent nuclear fuel, plugs are designed to close the deposition tunnels. The outer part of these plugs consists of a concrete dome made with selfcompacting-concrete, designed to have low pH to reduce negative effects on the bentonite clay buffer. A full-scale test has been performed to evaluate the performance of the plug, to test the installation and to verify underlying design assumptions. In this paper, the behaviour of the concrete dome is evaluated based on measurements, from casting the concrete until it was subjected to 4 MPa hydrostatic water pressure.
16.	Mohammadi Mohaghegh, Ali, 1980-, et al. (författare) Fire Spalling of High-Performance Basalt Fibre Concrete 2017 Ingår i: Nordic Concrete Research. - Oslo, Norway : nordic concrete federation. - 0800-6377. ; 57:2, s. 89-102 Tidskriftsartikel (refereegranskat)abstract The use of Macro Basalt Fibre Concrete (MBFC) for structural purposes is increasing in the Norwegian market. However, findings on properties related to fire spalling are scarce in the literature. Motivated by this, the authors present the results of a pilot experimental study on fire spalling properties of two types of basalt fibre concrete. The study results show that basalt fibres cannot prevent high-performance concrete (HPC) from fire spalling. Nonetheless, the comparison of the average spalling values indicates that use of basalt fibres probably does not increase the spalling propensity of the tested materials.

(författare) Flexural Behaviour of Medium-Strength and High-Performance Macro Basalt Fibre Concrete Aimed for Marine Applications 2017 Ingår i: Nordic Concrete Research. - Oslo, Norway. - 0800-6377. ; :57, s. 103-123 Tidskriftsartikel (refereegranskat)abstract This paper addresses the flexural behaviour of medium-strength, and high-performance concrete (HPC) reinforced with macro fibres made of basalt fibre reinforced polymer (BFRP) with the intended use for marine applications. Mechanical properties of the fibre concrete were studied through an experimental programme consisting of 18 beam specimens and 45-cylinder samples. In this study two types of concrete were used; medium-strength and high-performance concrete with the compressive strength of approximately 60-75 MPa and 90-105 MPa, respectively. The aspect-ratio of the used fibres were 65 and 83, respectively. The experimental results show that the post-cracking properties of macro basalt fibre concrete is a function of the fibre volume content.

(författare) Properties of Fresh Macro Basalt Fibre (MiniBar) Self-Compacting Concrete (SCC) and Coventional Slump Concrete (CSC) Aimed for Marine Applications 2015 Ingår i: Nordic Concrete Research. - Ålesund : NORSK BETONGFORENING. - 0800-6377. ; 52:1, s. 43-61 Tidskriftsartikel (refereegranskat)abstract Macro basalt fibres (MiniBar) with high corrosion resistance could be a suitable material in fibre concrete for marine applications. Due to the lack of knowledge about macro basalt fibre concretes (BFCs), the main objective of this paper is to assess the fresh state properties of macro basalt fibre conventional slump concrete and self-compacting concrete as the first step of developing BFC for concrete barges for fish farming on the west coast of Norway. To satisfy the requirements for marine applications, DNV and NS-EN standard rules are employed as the basis for the durability performance design. The concrete mix is designed to achieve densely compacted matrix by using the modified Andreasen & Andersen model as the particle size distribution target. In this paper, slump, flow-ability, passing-ability, fibre dynamic segregation and also flow rate as an indication for viscosity of different BFCs are measured and analysed. The result shows that there is a possibility to produce BF-SCCs with a fibre content of 1.15%. The fibres have an aspect ratio of 65.15. In addition, the mixture composed of a maximum gravel size of 16 mm shows a higher flowability in comparison with the maximum gravel size of 12 mm.
19.	Nilforoush, Rasoul (författare) A Refined Model for Predicting Concrete-Related Failure Load of Tension Loaded Cast-in-Place Headed Anchors in Uncracked Concrete 2019 Ingår i: Nordic Concrete Research. - : Sciendo. - 0800-6377 .- 2545-2819. ; 60:1, s. 105-129 Tidskriftsartikel (refereegranskat)abstract Current theoretical models for predicting the concrete cone breakout capacity of tension loaded headed anchors do not consider the influence of member thickness, size of anchor head, and orthogonal surface reinforcement. In the present study, the influence of the aforementioned parameters was studied both numerically and experimentally. Both the numerical and experimental results showed that the tensile resistance of headed anchors increases by increasing the member thickness or if orthogonal surface reinforcement is present. In addition, the anchorage capacity further increases with increase of the anchor head size.The current model for predicting the concrete cone failure load of tension loaded headed anchors were refined and extended by incorporating three modification factors to account for the influence of the member thickness, size of anchor head, and orthogonal surface reinforcement. The accuracy of the proposed model was verified based on the results of 124 tests on single headed anchors from literature.
20.	Nilimaa, Jonny, et al. (författare) Thermal Crack Risk of Concrete Structures : Evaluation of Theoretical Models for Tunnels and Bridges 2017 Ingår i: Nordic Concrete Research. - : Nordic Concrete Federation. - 0800-6377. ; 56:1, s. 55-69 Tidskriftsartikel (refereegranskat)abstract An approach for thermal crack risk estimations was introduced in the Swedish design guidelines BRO 94. The cracking occurs during the early hardening process because of the exothermic reactions between water and cement and often result in high repair costs and delayed construction. This paper studies and validates the inherent safety levels for one typical case of concrete structure. Three slab-frame structures were analysed and the original crack risk estimations were compared to the actual cracking and postcalculations were carried out, using actual parameters. This paper shows that walls with computed strain ratios over 70% were affected by thermal cracks.
21.	Sadagopan, Madumita, 1987-, et al. (författare) RE:Concrete- Study on Recycling of Concrete in Sweden 2017 Ingår i: Nordic Concrete Research. - Oslo. - 0800-6377. ; :56, s. 83-99 Tidskriftsartikel (refereegranskat)abstract Sweden’s concrete waste is recycled for use in low-utility purposes such as in the construction of sub-bases in roads but hardly as aggregates in new concrete. To analyse the potential for high-utility recycling, a literature study was conducted on the regulatory instruments, building standards, production and properties of recycled concrete aggregates and the recycled aggregate concrete for Sweden and European countries. Results urge statistics to quantify recycled concrete; regulations like source sorting of waste and selective demolition could potentially optimize recycled aggregate production. Also, the compressive strength of recycled concrete aggregate’s parent concrete influences the properties of the new concrete.

(författare) Plastic Shrinkage Cracking of Self-compacting Concrete: Influence of Capillary Pressure and Dormant Period 2019 Ingår i: Nordic Concrete Research. - : Norsk betongförening. - 0800-6377 .- 2545-2819. ; 60:1, s. 67-88 Tidskriftsartikel (refereegranskat)abstract This research investigates the effect of capillary pressure and the length of the hydration dormant period on the plastic shrinkage cracking tendency of SCC by studying specimens produced with different w/c ratios, cement types and SP dosages.The results show, that the cracking tendency of SCC was the lowest in case of w/c ratio between 0.45 and 0.55, finer rapid hardening cement and lower dosage of SP. The dormant period was prolonged by increasing the w/c ratio, using coarser cement and higher SP dosage. It was concluded that the cracking tendency of concrete is a function of the capillary pressure build-up rate and the length of the dormant period.
23.	Sjölander, Andreas, 1983-, et al. (författare) In-Situ and Laboratory Investigation on Leaching and Effects of Early Curing of Shotcrete 2019 Ingår i: Nordic Concrete Research. - : Walter de Gruyter GmbH. - 0800-6377 .- 2545-2819. ; 61:2, s. 23-37 Tidskriftsartikel (refereegranskat)abstract During the construction of a rock tunnel in Stockholm, several sections with leaching shotcrete (sprayed concrete) were found one year after the spraying was completed. An investigation was therefore conducted, and its results are presented in this paper. The amount of leaching after such a short time indicated that a one-sided water pressure existed in combination with a permeable shotcrete. The reason for the water pressure was likely a partly unsuccessful grouting that created sections with leaking water. The permeable shotcrete could be a combined result of insufficient curing and the use of accelerators, and the effect of in-situ curing was therefore investigated. A total of six slabs were sprayed and cured under different conditions in the tunnel. Test results according to standards indicated that curing has no significant effect on the development of mechanical strength or water penetration through the shotcrete. However, this is believed to be a result of the test method rather than the non-existing effect of curing. Lastly, some modifications to the test standard were proposed for future studies of in-situ curing.

(författare) Width and Edge Beam Effects on the Ultimate Behaviour of RC Bridge Overhangs 2019 Ingår i: Nordic Concrete Research. - : NORDIC CONCRETE FEDERAT. - 0800-6377 .- 2545-2819. ; 61:2, s. 131-152 Tidskriftsartikel (refereegranskat)abstract The bearing capacity of RC overhangs under concentrated loads can be dependent on the width of the slab. The goal of this paper is to investigate the effect of different widths using tests from the literature and non-linear FE-simulations as a reference. Shear force redistributions along the loading process and the shear concrete capacity are analysed. The shear effective width and the influence of an edge beam are also addressed. The results show that the bearing capacity of RC overhangs increase with the width until a transition area is reached and the increase flattens. An increased shear distribution sideways and posterior redistributions under the loading process are enabled. The shear capacity of concrete increases with the width and for loads close to the root an arch effect is observed. The edge beam contributes to a further increase of the ultimate capacity for wide enough overhangs. The effect of the width and the edge beam is not only quantitative but also qualitative since the failure mode and the critical section are influenced. Existing formulation for shear effective widths should be revisited. Experimental tests used for this purpose should consider wide enough specimens to capture the real behaviour of a bridge overhang slab.

(författare) Pb2+ adsorption by calcium silicate hydrate synthesized from steel slag 2015 Ingår i: Nordic Concrete Research. - 0800-6377. ; 52, s. 77-92 Tidskriftsartikel (refereegranskat)abstract This study aims to investigate the adsorption properties of Pb2+ by calcium silicate hydrate synthesized from steel slag. The influence of various factors on the adsorption properties was investigated. The static desorption test was conducted to investigate the leaching of Pb2+. The kinetic model and isotherm model of adsorption are then discussed. Results show that Pb2+ adsorption capacity of C-S-H depends on Ca/Si ratios. Kinetic adsorption data is in consistence with Lagegren pseudo-second-order model, and steady-state data fits to Langmuir isothermal model. Leaching result demonstrates that Pb2+ ions are stably adsorbed by C-S-H structures.
26.	Williams Portal, Natalie, et al. (författare) Experimental Study on Anchorage in Textile Reinforced Reactive Powder Concrete 2017 Ingår i: Nordic Concrete Research. - 0800-6377. ; 57:2, s. 73-88 Tidskriftsartikel (refereegranskat)abstract The EC funded project SESBE (Smart Elements for Sustainable Building Envelopes) focused on utilizing new types of cementitious materials for reducing the mass and thickness of façade elements while increasing their thermal performance. A method enabling the quantification and verification of the required anchorage length for a given textile reinforced reactive powder concrete (TRRPC) is presented. At the material level, tensile tests were conducted to determine the tensile properties of the reinforcement. Pull-out tests were applied to quantify the required anchorage length, while uniaxial tensile tests were performed to quantify the ultimate strength and verify the suitability of the anchorage length at the composite level. The combination of these methods was deemed useful to determine the overlapping length required for larger scale façade applications.
