Self-Compacting Concrete (SCC) is a highly flowable, self-levelling concrete. Just as in Fibre Reinforced Concrete (FRC), fibres can be incorporated into SCC also to get FRSCC. In the present study hybrid fibres namely, Polypropylene and hooked ended Steel fibres are incorporated in different volume fractions and their fresh and hardened state properties have been studied. Fly ash and Silica Fume obtained as waste from industries are used as replacement for cement, the replacement being 10% and 5% respectively. The behaviour of HFRSCC under compression, tension and flexure has been experimentally observed. The stress-strain behaviour of SCC and HFRSCC have also been studied by varying the combinations of volume fractions of hybrid fibres.

Strength And Durability

This paper studies the development of hybrid fibre reinforced self-compacting concrete as per Nan Su criteria. Results predicted that various packing factors adopted in the study are 1.12, 1.14, 1.16 and 1.18. Fine aggregate /Total aggregate ratios (s/a ratio) adopted in the study are 0.5, 0.53 and 0.57. The optimum combinations of packing factor and s/a ratio are found to be 1.12 & 0.53 and 1.14 & 0.57 for M30 grade SCC mixes because these optimum PF and s/a ratio combination gives comparatively better particle packing density in SCC mixes. Better particle packing density enhances the microstructure of SCC mix subsequently more strength and durability can be achieved. As PF increases powder content decreases and aggregate content increases requiring more paste to make the SCC mix workable. Less value PF will have high particle packing density yielding more strength due to improved microstructure of SCC mixes. At PF & s/a combinations of 1.12 & 0.53 and 1.14 & 0.57, the workability of SCC mixes is superior because of high paste volume and less aggregate content. Compressive, split-tensile and flexural of M30 grade SCC mixes made with optimum combinations of packing factor and s/a ratios are found to be high.

Proof that, just as results, self-compacting concrete is complete benchmark in the area of construction. Because of its highly profitable qualities, Self Compacting Concrete (SCC) extremely favoured and used drastically all over the construction world. SCC is that creative concrete which does not require any help of vibration for arrangements and compaction. It is shown that SCC have capability of complete filling formwork by property of flow under its self weight. Hence, it attain over all compaction, even in case of choke reinforcement. The main intent of this research paper is to find the fresh characteristics of basalt- glass hybrid fibre reinforced self-compacting concrete like T50 cm, spread flow, L-box, V funnel and hardened characteristics such as compressive strength, ultrasonic pulse velocity (UPV) and flexural strength at 7 and 28 days. Basalt-glass hybrid fibre reinforced self-compacting concrete has shown improved hardened characteristics with the addition of fibres.
