Evaluation of Strength and Durability of Geo Polymer Concrete

Abstract

It is important to durable of structure and reduce CO2 emission through the greater use of substitute for Cement. The use of supplementary cementitious materials as partial replacements for the cement in concrete will play a significant role with respect to the environmental control of greenhouse effects and global temperature reduction. The development of geopolymer concrete (GPC), processing of geopolymer using fly ash, GGBS in combination with sodium hydroxide and sodium silicate solutions, offers a promising alternative to ordinary portland cement concrete. This study compares the different ratios of fly ash to GGBS where, 50:50,60:40,40:60 ratios and differing the molarities of alkaline solutions which are 8M,10M and 12M and comparing the strengths of the above ratios and conducting durability characteristics of fly ash and GGBS based geopolymer concrete by conducting test procedures like acid attack test
