High strength self-compacting fibre reinforced concrete: behaviour in the fresh and the hardened state
Self-compacting concrete (SCC) offers significant benefits in terms of improved working conditions, reduced labour costs and gives the possibility to cast concrete under special conditions (casting in remote areas, casting in areas with congested reinforcement, casting elements with special architectural shapes). Adding steel fibres to a concrete normally reduces its workability. Nevertheless, selfcompacting fibre reinforced concrete's, even with high strengths, could be developed. Such types of concrete are especially favourable in structural elements subjected to bending. In order to investigate the potential of such materials bending tests on SCHSFC's (Self- Compacting High Strength Fibre Concrete's) were carried out. Three-point bending tests were conducted on SCHSFC's with cube strengths up to fccm = 115 N/mm(exp-2). To see whether SCC demonstrates also improved performance compared with conventional (not selfcompacting) concrete, the test results were compared with the results of earlier experiments obtained with conventional fibre reinforced concrete (FRC) with the same strength. Along with the experiments on the mechanical characteristics, a study on the properties in the fresh state was carried out.
