Today concrete is most widely used construction material due to its good compressive strength and durability. Developing upon the nature of work the cement, fine aggregate, coarse aggregate and water are mixed in specific proportions to produce plain concrete. Self compacting concrete(SCC) is highly flowable yet stable concrete that can spread readily into place and fill the formwork without any consolidation and without undergoing any significant segregation. The present paper deals with the behaviour of SCC with self curing concrete and standard glass fibre reinforced self compacting concrete (sgfrscc). The purpose of this study was to investigate the workability and mechanical properties of plain SCC, SCC with self curing and sgfrscc. The laboratory testing included slump flow test, L-box, V-funnel, J-ring, compressive strength, splitting tensile and flexural strength test. It was observed that the confinements of the concrete has increased by after 28 days of curing 32.5% increase in compressive strength,22.7% increase in split tensile strength and 25.72% increase in flexural strength and with the addition of 0.9% of glass fibres compared with ordinary SCC. The optimum percentage of glass fibre that should be a added to get better results in 0.9%. Self-curing concrete is one of the special concrete in mitigating insufficient curing due to human negligence paucity of water in arid areas. The present study involves the use of shrinkage reducing admixture SAP (super absorbent polymer) in concrete which helps in self-curing for better hydration and strength. The affect of admixture (SAP) on compressive strength , split tensile strength by varying the percentage of sap by weight of cement from 0% to 3% were studied for M30 mix. It was found that sap could help in self curing by giving strength on par with conventional curing. © Research India Publications. Source
