The effect of Waste Glass as Partial Replacement of cement on Properties of Concrete

The utilization of solid waste materials or industrial waste as partial substitution of cement is growing in construction industry all around world to reduce the consumption of cement consequently reduction in CO2 emission into the atmosphere and reduction in energy consumption. The aim of this study is to improve the strength of concrete made by replacing the cement with waste glass. In this study the cement was replaced with waste glass as 5, 10, 15, 20 and 25% by weight of cement with constant water to binder ratio of 0.5. One mixture of control concrete and five modified concrete mixtures prepared with replacement of cement with waste glass were prepared. Workability, density of hardened concrete, Compressive and tensile strength of control and modified concrete were tested. The experimental test results revealed that, significant improvement was observed at 10% replacement of cement with waste glass on the investigated properties of concrete.
