Abstract

CO2 is released into the atmosphere during the manufacture of Ordinary Portland Cement (OPC). Fly ash, a by-product of the coal industry, is used to replace OPC in concrete. It contains a lot of silicate gel and is mixed with an alkaline solution to make good concrete. Increased fly ash fineness improves compressive strength while lowering porosity. Advances in modern bio technology is possible freedoms for monetary use of agro-mechanical deposits like sugarcane bagasse ash and fibre. The flexural behaviour of Geopolymer Concrete RCC beams with and without sugarcane bagasse fibre, i.e. GPC and GPCF of G 40 grade, equal to M40, is presented in this study. The 150*150 mm beam is cast across a 1,200 mm effective span and tested for failure under static loads. The ultimate load and load displacement responses of GPC structural elements with and without fibre are measured and compared to normal GPC and conventional concrete elements. The findings suggest that SCBF improves the flexural strength, service load, and peak load of GPC elements.
