Use of waste material in concrete is important for environmental aspect. Granulated Blast Furnace Slag is a waste product of steel foundry. Our experimental study is to investigate the impact of Ground Granulated Blast Furnace Slag in to the concrete by partial substitution of cement content and at the same time the effect of introducing glass wool into the concrete. In this work cement is partially replaced with GGBFS (0%10%20%40%) by weight in the glass wool mixed (0.1% of the weight of cement) concrete. The grade of concrete is M25 and water cement ratio is 0.47 taken as a reference. Cubes, cylinders and prisms are cast and tested for 7, 14 and 28 days. The GGBFS have fineness about 96% and specific gravity 2.98. One effective way to reduce the environmental impact is to use mineral admixtures, as a partial replacement both in concrete and mortar, which will have the potential to reduce costs, conserve energy, and minimize waste emission. Also it requires checking various properties of concrete like compression test, flexural test with variation of GGBFS and constant dosage of glass wool. Mineral admixtures are found in various forms in nature, including blast furnace slag, fly ash, and silica fume. The use of mineral admixtures improves the compressive strength, pore structure and permeability of concrete and mortar because the total porosity decreases with increasing the hydration time. Recycling of waste material saves natural resources, saves energy, reduces solid waste, reduces air and water pollution and reduces greenhouse gases.
