Abstract:

The ecosystem is polluted by the emission of green house gas CO2 due to the production of ordinary Portland cement (OPC). An alternate material is substituted with low calcium i.e. Fly ash. Fly ash which is a by-product of coal industry is introduced to replace OPC in the concrete. Fly ash is rich in silicate gel with alkaline solution, to produce a good concrete. Increase in fly ash fitness increases the compressive strength and reduces the porosity. This study is presented on the flexural behaviour of geopolymer concrete (GPC) beams and control cement concrete beams. The beams are cast over an effective span of 3000mm and tested up to failure under static loads. The load displacement response of the geopolymer concrete beams and control beams are obtained to compare with the theoretical results. The result implies that there is an increase in flexural strength, service load, and peak load of geopolymer concrete beams
