This The demand of concrete is increasing day by day and cement is used for satisfying the need of development of infrastructure facilities, 1 tone cement production generates 1 tone CO2, which adversely affect the environment. In order to reduce the use of OPC and CO2 generation, the new generation concrete has been developed such as Geopolymer Concrete. It uses Fly ash and Alkaline Solution as their binding materials Geopolymer requires oven curing temperature 60°C for a period of 24 hours. The present work is to study the effect of waste Kota stone powder on Fly ash based Geopolymer Concrete as partial replacement with fly ash. The alkaline solution used for present study is sodium silicate (Na2SiO3) and 12M sodium hydroxide solution (NaOH) and various sodium silicate to sodium hydroxide ratio 2.0, 2.5 and 3.0. The casted cube and cylinder will be cured in oven heated at 60°C for 24 hours and to ascertain the behavior of Geopolymer Concrete mixed with Kota stone powder as partial replacement at 0%, 5% and 10% with fly ash, thereby measuring the influence of compressive strength (cube and cylinder) after 7 days, 14 days, and 28 days of curing, split tensile strength after 28 days of curing and porosity test after 28 days.

Geopolymer, molarity of sodium hydroxide, sodium silicate to sodium hydroxide ratio, Kota stone replacement.
