Abstract

In the recent past, Geopolymer concrete has emerged as a potential alternative to the OPC concrete in the light of global warming, which is a major environmental concern all over the world. A considerable work has been reported on the development and poperties of Fly-ash based Geopolymer concrete, but only a little work can be seen in the past literature on blended geopolymer concrete. The present work investigates the strength properties of Ternary blended geopolymer concrete with different combinations of fly ash, GGBS, and Wallastonite in which 50% of fly ash was kept constant in all the mixes and remaining 50% with Wallastonite and GGBS in the ratios of 15%:35% , 25%:25%, 35%:15% respectively were taken. All the mixes are designed for 40 Mpa and the strength properties, such as compressive strength, split tensile strength, and flexural strength tests were determined on all the mixes. Strength tests reveal that a mix with combination of 50% fly ash and 25% Wallastonite and 25% GGBS has shown better performance over other mixes and chosen as Optimal mix.
