Experimental Investigation on Rebar Corrosion in Combination with Fibres
- 2014

In: Proceedings of the XXII Nordic Concrete Research Symposium. - 9788282080439 ; , s. 532-
-
Conference paper (other academic/artistic)abstract
- In this paper, early results from an on-going project aimed at investigating the influence of fibre reinforcement on corrosion of rebar are presented. Resistivity of mixes containing fibres was reduced when compared with plain concrete while chloride migration seemed to remain unaffected. On the mechanical properties, results showed that while the flexural behaviour was greatly enhanced by addition of fibres up to 0.5% vol., the variation in compressive strength was negligible regardless of the fibre type. Early results from the main experiments indicated atendency of earlier corrosion initiation with increasing crack width, and that the initiation time was somewhat delayed for the fibre reinforced specimens.

Industrial bridge building- An effective bridge construction process through an integrated design and construction process
- 2014
-
In: Nordic Concrete Research. - 0800-6377. - 9788282080439 ; 2014:2, s. 79-82
-
Conference paper (peer-reviewed)abstract
- This PhD-project aims to develop and industrialise bridge building, in order to achieve a more efficient and sustainable bridge construction process. The advancements of several key areas - materials science and technology, design and analysis methods, production techniques and information and communication technology - have resulted in a vast potential to rationalise the process and renew the designer's role. Initially, the project will define effective bridge construction criteria’s by means of interviews and case-studies. The work should result in an integrated design and production process. This project is a collaborative project, involving: Swedish Transport Administration, WSP and Chalmers.

Recommendations for Finite Element Analysis for Design of RC Slabs
- 2014
-
In: Nordic Concrete Research. - 0800-6377. - 9788282080439 ; 2014:2, s. 39-42
-
Conference paper (peer-reviewed)abstract
- The finite element method (FEM) is increasingly used for design of reinforced concrete structures. 3D FE analysis can provide more accurate structural analysis, but to use its full strength in daily design a number of critical issues have been addressed. Practical guidelines are provided for detailed design of reinforced concrete slabs. Recommendations are given on linear FE modelling, e.g. regarding geometry, support conditions and mesh density, as well as on the use of analysis results, e.g. regarding stress concentrations, choice of critical sections and redistribution widths for practical reinforcement design.

Deterioration of Concrete in Hydraulic Structures due to Frost Action
- 2014
-
In: Nordic Concrete Research - Proceedings of XXII Nordic Concrete Symposium. - 0800-6377. - 9788282080439 ; 2014/2:50, s. 483-486

Conference paper (peer-reviewed)abstract
- Climatic conditions during the winter in countries situated in the north can be considered severe. This is especially true for hydraulic structures, such as hydro power structures, dams, harbours, canals and some bridge foundations. Freezing of concrete in contact with unfrozen fresh water may have a considerable impact on the deterioration process of concrete. This paper presents results obtained in experimental investigations based on observations of superficial and internal damage to concrete in hydraulic structures in Sweden. It was shown that superficial damage at the waterline is caused by interactions between leaching, frost action and abrasion. Further, the results indicate that internal damage to some thin concrete dams has been due to formation of macroscopic ice lenses causing spalling of concrete. Knowledge about degradation mechanisms and how they interact is crucial in order to be able to perform durable repairs.

Structural Assessment of Bridge Deck Slabs
- 2014
-
In: Nordic Concrete Research. - 0800-6377. - 9788282080439 ; 50, s. 453-456
-
Conference paper (peer-reviewed)abstract
- The overall aim of this project is to develop improved methods for assessment of the load carrying capacity and response of bridge deck slabs. This research project was carried out by laboratory experiments, analytical computational analysis, linear and non-linear finite element analyses. The on-going non-linear analyses of tested slabs show possibility to accurately predict the load carrying capacity and to realistically simulate the crack pattern and load distribution.
