Waste glass powder and cubic boron nitrite powder is much useable powder as a replacement of cement and fine aggregate in the concrete mixture. Waste glass powder is a waste material which is also called ground glass powder. In now a dayâ€™s waste materials is very much use in replacement of ingredient of concrete. In this study we use type of replacement to make a perfect and economical mixer which gives us more strength and durability of concrete. We use waste glass powder (5%, and 8%) as replacement of cement by the weight of cement, cubic powder (10% replacement by weight of cement) and add hooked ended steel fiber (1.35% and 2% add by total volume of concrete) to make a three type of uniform mixture to check the durability and strength of concrete. Total number of 27 cubes specimen (150Ã—150Ã—150 mm) and 27 cylinder specimens (300mm length and 150mm diameter) were cast with different composition of glass powder, cubic powder and hook ended steel fiber. In this investigation the sample containing replacement of cement by cubic powder and waste glass powder with hook ended steel fiber and all sample of concrete mixture is designed with water cement ratio (w/b) of 0.45. The compressive strength and split tensile strength were calculated for all three type of mixture at the end of 7 days, 14 days and 28 days of curing period and compare the all result of normal concrete and waste material concrete results at testing period. It was found that the 5% replacement of cement by glass powder and adding of 1.35% steel fiber gives us 32MPA maximum compressive strength and 3MPA is maximum split tensile strength. The result revealed that incorporation of CP, GP and utilization of different types of steel fibers significant affected the mechanical properties of concrete.
