Experimental investigation of characteristic compressive strength and modulus of elasticity of geopolymer concrete.

Natural contamination is the most pressing issue facing the globe now. As a result of the industrial revolution. There is a massive release of ozone-depleting compounds (such as CO2) into the atmosphere. By increasing the use of modern results, we can reduce the impact of pollution on the environment. There comes a time when "GEO POLYMERS CONCERTE" is the concept. The entire cement content is 100% replaced with Fly ash, Silica flumes, and gypsum are being replaced. For material binding, alkaline liquids such as NaOH and Na2SiO3 are utilized. In our experimental investigation, we utilized low calcium (class F) fly ash obtained from the Thermal Power Plant in Koradi, Nagpur. Alkaline activators used included Sodium Hydroxide in flake form with a 98% purity and Sodium Silicate Solutions consisting of Na2O (14.7%), SiO2 (29.4%), and water (55.9%). We experimented with ratios of 1:1.18:2.58 and 1:1:2, employing concentrations of 8 M and 16 M for NaOH. The focus of this research delved into evaluating the Modulus of Elasticity and Compressive Strength by established standards such as the Australian Standard (3600-2005) and Indian Standard codes.
