Abstract Construction cost is increasing rapidly due to materials used for it and it can be reduced by using cost effective materials. Many experiments are done to obtain cost effective concrete with good strength and good quality. The study of cost effective concrete by using industrial waste product Fly ash. Fly ash is used as cement replacement. In this cement concrete of M40 grade design is carried out as per is codes .The tests are carried out to obtain maximum strength of concrete so cement is replaced by fly ash of various percentages like 10%,20%,30%,40%,50%,60% and 70% by adding water cement ratio of 0.35 and hyper plasticizer is used to reduce the water cement ratio to increase workability. Cubes were casted of size 150mm×150mm and total 84 number of cubes were casted for different curing periods of 7, 14, 28 and 56 days. After curing cubes are tested for 7, 14, 28 and 56 days by using compressive testing machine respectively. For 28 days of curing period, the maximum compressive strength is obtained for 20% cement replacement by fly ash gives good strength and for these to gain early strength alccofine is added as additive material of 3%, 6%, 9% and 12% for 28 days curing period. In these 12% alccofine is added and 50% cement replacement by Fly Ash gives better compressive strength. Test results shows that using fly ash can used as cost effective and good quality of concrete, by using alkofines we can improve the early age strength. Keywords: Fly Ash, Alccofine, Hyper plasticizers
