Abstract: The geopolymer concrete is considered as a third generation concrete after lime and cement the using of high calcium fly ash in concrete is significant and considered as the suitable option for the next generation in terms of strength and durability aspects. Normally the usage of fly ash in concrete can reduce the cost and increase the long term aspects in durability. Here the fully replacement of cement with high calcium fly ash was done. The replacement of high calcium fly ash was done with changing the percentage of total aggregate content in the total density of the concrete. The replacement was done with 60% 65% 70% 75% 80% .an alkali liquid ids used as a by product to react with fly ash to produce binder. The sodium hydroxide and sodium silicate solutions with 14M were used as a source material.
