This work reports the outcome of an experiment carried out by using milled glass (MG) of varying percentages (20%, 40% and 60% by weight)of cement in concrete making. MG was sourced for and milled to required fineness. The concrete was batched with mix ratio of 1։2։ 4. Concrete Cube specimens produced were allowed to cure for 7-28 days and compressive strength, slump and setting time tests were carried out and were compared with those of conventional concrete (0% MG). Results obtained showed that compressive strength of the concrete increased with increase in length of curing age, but decreased as the percentage of MG increased. However, the strength still remained in the allowable range of workability for concrete in line with British standard. MG replacement of 20% was found to be the most suitable mix considering the strength and safe use of the concrete. It was concluded that MG replacement of 20% showed no significant loss in strength compared to the control sample and is stable and could be acceptable in most concrete. At the long run. Waste glass that currently constitutes waste concern in built environment in Nigeria can best be managed through alternative use in concrete production.
