Abstract
Recently most developing countries are having problems of shortage of waste landfill sites. Due to this constraint, it is proposed to regenerate the glass waste and use it as a sand substitute in the production of concrete to minimize the environmental pollution This study investigates and analyzes the effect of the windscreen glass waste on replacement of sand into the mortar mixture on water absorption test. The mix design proportion of the mortar is 1:3 and with water cement ratio of 0.5 and with the partial replacement of 10%, 20%, 30% of sand to windscreen glass waste, taken at age 7 days, 14 days and 28 days of curing session. From this study, it found that mortar with replacement with windscreen glass waste produced a better result as compared to control sample. In term of water absorption, 30% replacement of windscreen glass waste at 28 days curing has produced the lowest water absorption level.
