摘要：The consumption of Ordinary Portland cement (OPC) caused pollution to the environment due to the emission of CO 2 . As such, alternative material had been introduced to replace OPC in the concrete. Fly ash is a b y-product from the coal industry, which is widely available in the world. Moreover, the use of fly ash is more environmental friendly and save cost compared to OPC. Fly ash is rich in silicate and alumina, hence it reacts with alkaline solution to produce alumina silicate gel that binds the aggregate to produce a good concrete. The compressive strength increases with the increasing of fly ash fineness and thus the reduction in porosity can be obtained. Fly ash based geo polymer also provided better resistance against aggressive environment and elevated temperature compared to normal concrete. This p aper presents the laboratory investigation to study the co mpressive strength with effect of concentration o f molarity and curing temperature. It is co ncluded that higher concentration of molarity and increase in temperature increases the compressive strength
