Abstract – The main objective of this current study is to develop a cement free concrete material because of the greenhouse effect during the manufacture of cement. It is reported that everyone tone production of cement emits one tone carbon dioxide which causes global warming and in broad sense disturbs the entire ecological system. It results the promotion of geo polymer concrete where silica and alumina will bind together with alkaline solution during the process of polymerization. The researchers taken greater initiatives in geo polymer concrete there is no specific study related to the mix design because of commercialization and patenting. Hence the authors interested in identifying specific mix design using trial proportion of low calcium fly ash and alkaline solutions (sodium silicate and sodium hydroxide). This investigation deals with five different trial mixes with different molarity of NaOH (8M, 10M, 12M and 14M) and super plasticizer combinations under the curing temperature of 60ºC. The fresh and hardened properties have been studied.

Key Words – sodium silicate; sodium hydroxide; fly Ash; compressive strength; oven curing
