Aptness of Waste Glass Powder on Strength of Portland Cement Concrete

S. Suehail, P. Mudasir

Abstract: Portland cement is main binder in concrete whose production is not environment friendly as one ton of cement produces almost 0.7 ton of CO2 which cause global warming through green house gasses, therefore, cement replacement either partially or completely is required to lower production of cement. In this research cement was partially replaced with 10 %, 20 % and30 % white waste glass powder finer than 150m. At fixed W/C ratio 0.43 and mix proportion with cement: sand: coarse aggregate= 1: 1.19: 2.68, it was found with 20 % cement replacement compressive strength improved than reference mix. Also porosity and void ratio reduced.
