Abstract

Energy saving in building technology is among the most critical problems in the world. Thus it is a need to develop sustainable alternative to conventional concrete utilizing more environmental friendly materials. One of the possibilities to work out is the massive usage of geo polymer concrete to turn them to useful environmental friendly and technologically advantages cementitious materials. In the present study metakaolin and Ground Granulated Blast furnace slag (GGBS) is used to produce geopolymer concrete. Geopolymer concrete is prepared by using alkaline solution of sodium silicate mixed with sodium hydroxide in the ratio of sodium silicate to sodium hydroxide is 2.5 and the concentration of sodium hydroxide is 10M is considered in this experimental investigation. The geo polymer concrete specimens with different proportions of Metakaolin and GGBS were cast and tested for compressive strength, Split Tensile Strength and Flexural Strength for 3, 7 and 28 days and cured at ambient temperature.
