Study and experimental investigation of flow and flexural properties of natural fiber reinforced self compacting concrete

摘要

The essentiality of self -compacting concrete can be understood from the fact that there is an increasing problem of lack of skilled labor in the construction industry. The benefit of SCC is that it provides faster construction period and allows an early development of strength for concrete. The above paper deals with flexure and flow properties of self -compacting concrete reinforced with a combination of steel with sisal and abaca fibers. Three percentages of sisal (0.5%,1%,1.5%)or three of abaca (0.5%,1%,1.5%) are mixed with a uniform 0.3% and 0.6% of steel fibers. Split tensile strength and flexure strength are evaluated at 7 days and 28 days for various specimens of self -compacting concrete made by variation of fiber provides an understanding of mechanical properties and tests like Slump flow, J –ring and U-box test are performed for an understanding of flow of self -compacting concrete.
