Abstract
Waste glass is one of the biggest contributors in waste production in Malaysia which can be used as partial sand replacement in concrete. Silica exists in waste glass components made it becomes a pozzolanic material and suitable to be used in a concrete mixture. The performance of the waste glass as fine aggregate was reviewed by considering the workability of fresh concrete, the strength, and the splitting tensile of hardened concrete. The range of the replacement waste are 0%, 10%, 20% and 30%. The influence of the waste glass on the microstructure of the concrete also have been evaluated. A total of seventeen previous research papers were collected and review based on the parameters selected. The results shows that replacement of waste glass in concrete give a positive impact for all selected parameters with 20% replacement represent as an optimal percentage replacement. The microstructure of the waste glass concrete resulting that more voids created after 20% replacement of waste glass which affects the compressive strength and split tensile strength of the concrete thus make the optimum replacement percentage is 20% replacement.
