Fibre-reinforced self-compacted concrete

Despite the reduced workability of FRC, recent studies have shown that it is possible to produce fibre-reinforced self-compacted concrete (FR-SCC), with good flow properties and suitable properties. Akcay and Tasdemir (2012) have studied steel fibre in FR-SCC and found that the main parameter affecting the flowability of FR-SCC is the geometry of fibres, rather that the fibre strength. El-Dieb and Taha (2012) show that suitable workability of FR-SCC depends on the fibre content. For polypropylene fibres, the maximum fibre content should be 1000, 1200 and 1300 g/m for SCC mixtures with cement content 350, 400 and 500 kg/m respectively. For steel fibres, one should limit the fibre aspect to 50, 90 and 100 kg/m for SCC mixtures with cement content of 350, 400 and 500 kg/m respectively.
