Study on Compressive Strength of Geopolymer Mortar

India is one of the Developing countries that needs to face the environmental pollution. Have many ways to reduce environmental pollution that causes by production of Portland cement and cause by the increasing of waste material. This paper studies the strength development in geopolymer mortar using industrial by-products. Geopolymer is the term used to represent the binders produced by polymeric reaction of alkaline liquid with silicon and aluminium as source materials. The by-product materials considered in this study are combination of GGBFS and Fly ash. The experimental program involves casting of geopolymer mortar cubes and testing them at 1 day, 3 days and 7 days for compressive strength. Different parameters considered in this study are ratio of sodium hydroxide to sodium meta silicate (1:1 & 1:2 ) and alkaline fluid to binder ratio Keeping 12-Molarity of the alkaline liquid as constant. It can be concluded that the strength increased with an increase in the quantity of GGBFS.
