Characterization of fiber reinforced self-compacting concrete by fly ash and cement

Abstract

Self-compaction concrete is huge flow capable kind of concrete that flows through the appearance lacking of any shaking. Self-compacting concrete is a non-separating concrete those can be located by its own mass. It has fresh properties approximately passing capacity, flowing ability, filling ability and segregate resistance which can be estimated by conducting workability tests like L-Box, V-Funnel, U-Box, J-Ring and Slump cone flow. The characteristics of self-compacting concrete replacing by fly ash to improved the fresh state stability, rheological properties and compressive strength and steel fibers generating a highest compression and splitting tensile strengths in self-compaction concrete. The effects of fly ash as 5%, 10%, 15%, 20%, 25%, 30% weight of cement and of steel fibers as 0.5%, 1.0%, 1.5, 2% with taking of the highest (optimum) value of fly ash to get maximum strength. The strength characteristics like compression, split, tensile and flexural strengths. And longevity (durability) properties like sorpitivity, rapid chloride permeability test (RCPT) of self-compacting concrete.
