Abstract

The production of Ordinary Portland Cement (OPC) causes pollution to the environment, due to the emission of CO2. Geopolymer Concrete,an alternate materialis introduced to replace OPC. Low Calcium Fly ash, a by-product from the coal industry, is widely available in the world. Silicate and Alumina are rich inFly ash.Hence it reacts with alkaline solution to produce Alumina silicate gel that binds the aggregate to produce a good concrete. The compressive strength increases with the increasing of fly ash fineness and thus the reduction in porosity can be obtained. The flexural behaviour of Geopolymer concrete (GPC) beams and control cement concrete beams are examined. The designed compressive strength of concrete is 50N/mm2. A total of four beams is castover an effective span of 3000 mm and tested up to failure under static loads. The load-displacement response of the geopolymer concrete beams and control beams are obtained and compared with the theoretical results. The results show that thegeopolymer concrete beams exhibit increased flexural strength.The deflections at different stages including service load and peak load stage are higher for GPC beams.
