Strength of the concrete is a very important factor for the safe design of concrete and safe construction. Nowadays high strength concrete has an important role in the construction of different structures. It is difficult to enhance the strength of the concrete and enhancing strength requires a lot of changes in the mix design. The present study is to develop Geopolymer concrete to increase the compressive strength of low nominal mix proportions using alkali actuators like NaOH and Na 2 SiO 3 solutions. Geopolymer concrete is one of the best alternative concrete for conventional and other cement concretes for many reasons. The Geopolymer concrete is prepared with ground granulated blast furnace slag (GGBS) and silica fume (SF) as a binder. NaOH and Na 2 SiO 3 solutions are adopted as alkali activators. Quartz sand is used as fine aggregate along with normally used coarse aggregate. Cubes are prepared with different combinations of ingredients and after 28 days of ambient curing conditions, the cubes are tested for compressive strength. And this study is conducted in summer, monsoon and winter seasons to study the effect of seasons on ambient curing of the Geopolymer concrete.
