STRENGTH OF GGBS AND FLYASH BASED GEOPOLYMER CONCRETE USING GEOACTIVATOR

Abstract

Geopolymer concrete is a new type of concrete which is a new development in the world of concrete in
which cement is totally replaced by GGBS, Flyash and Geo activator solution is to act as binder in the concrete
mix.An attempt was made to achieve desire strength and durability In source of material 100%GGBS, 75%GGBS &
25%Flyash, 50%GGBS & 50%Flyash With different activator to binding materials ratio i.e, for the 1:1.3:3.1 mix
proportions. The test specimens where 100×100×100mm cubes ,100mm×200mm cylinders prepared and ambient
temperature curing conditions. The Geopolymer concrete specimens are tested for their compressive strength at the
age of 28 days. The Geopolymer concrete mix formulations vth compressive strength ranging from 30-72Mpa have
been developed. The test result indicates that the combination of Flyash & GGBS can be used for development of
Geopolymer concrete.
