Properties of Fresh Macro Basalt Fibre (MiniBar) Self-Compacting Concrete (SCC) and Coventional Slump Concrete (CSC) Aimed for Marine Applications

• 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.
