PROSPECT OF PARTIAL UTILIZATION OF WASTE GLASS POWDER AND WASTE PAPER SLUDGE ASH IN CONCRETE

This research examines the possibility of using waste glass as partial replacement of fine aggregates and waste paper sludge ash as partial replacement of cement in concrete. The fine aggregates were replaced partially up to 40% by weight using waste glass powder and cement was replaced partially up to 20% by weight using waste paper sludge. The normal concrete of M 25 design mix was used as a reference standard. The cube specimens of size 150 mm for all mixture compositions were tested for compressive strength, light weight character, water absorption (durability) and cylinder specimens of size 300mm length and 150 mm diameter were tested for splitting tensile strength. The light weight tests and water absorption tests were carried out at 28 days of age. The compressive strength and splitting cylinder tests were carried out at 7, 28 and 60 days of age.
