Abstract

The present work is focussed on the optimization of mix proportions to satisfy the self-compatibility requirements as per EFNARC [march 2006] guidelines and to assess the mechanical properties of concrete made out from these industrial by-products adding partially with GGBS in cement called self compacting concrete (SCC) and concrete made with (GGBS+Fly ash) named as Self Compacting Geo-polymer Concrete (SCGPC) and concrete made with incorporation of steel fibers for the optimized SCGPC mix named as Self-Compacting Geo-Polymer Fibre Reinforced Concrete (SCGPFRC) mixes were prepared. The fresh properties, as well as the hardened properties, were studied. The physical durability was also studied with the abrasion resistance test. The fresh properties of SCGPC were better than SCC and SCGPFRC. Although there is a slight decrease in strength for SCGPC, when compared to conventional concrete(100% cement) and SCC, but it fulfill the strength requirements by achieving the target strength. With the introduction of fibres to the SCGPC, the flexural strength and split tensile strength of SCGPFRC is significantly increased when compared to SCGPC mixes. It can be inferred that at fiber content of 1.5% (SCGPFRC2) the value of flexural strength and split tensile strength was found to be increased by 15.73% and 40.72% respectively.
