Experimental Study on Utilization of Hybrid Fibers in Self Compacting Concrete

Self compacting concrete is a non segregating concrete that is placed by means of its own weight. It is highly flow able concrete that can spread without need of vibration. In this study steel and polypropylene fiber are used as hybrid fiber to enhance the workability of the concrete. In addition to this, CONPLAST SP 430 is used as a chemical admixture which is added to SCC by the volume of 2 of cement. These components like hybrid fiber and super plasticizer are added to the concrete to improve the better strength and durability of SCC. In this study, the various mix proportions of fibers discussed in this study are 0 , 0.25 , 0.5 , 0.75 , 1 , 1.5 determined by preliminary test on self compacted materials. By this desired compositions test for fresh concrete such as slump flow, L box and V funnel, U box, J ring are performed for SCC. It is found that compression and split tensile strength has been improved by the addition of hybrid fibers at 1 respectively. This experimental investigation is carried out to improve the compressive, split tensile and flexural strength in SCC for obtaining the optimum value. S. Janani | P.
