An Experimental Study on Strength and Durability Properties of GGBS based Geopolymer Concrete

Abstract

Huge amount of energy is consumed during for the manufacture of OPC , also emits CO2 and other greenhouse gases leads to global warming. Nowadays the production of Portland cement and consumption of concrete is increasing enormously. Geopolymer concrete is considered as a new approach towards sustainability in which different industrial by products are used to replace OPC as a binder completely which minimizes the CO2 emission. In this study, attempt is made to develop GGBS based geopolymer and the characteristic strength is studied. The concentration of sodium hydroxide solution was kept up as 10M. The compressive, split tensile and flexural strength of the GGBS based geopolymer concrete was studied at different ages like 3, 7, 28 days. Microstructural study has been conducted with SEM analysis to study the effect of temperature in curing of geopolymer.Also conducted the durability studies on geopolymer concrete exposed to severe exposure such as acidic and basic environments.
