The recent industrialization and urbanization have placed heavy demand on the usage of concrete as construction materials. Therefore, large quantities of raw materials and natural resources are required to meet the large concrete production worldwide. Concrete is made up of cement, sand, stone, and admixtures to alter its properties when necessary. Concrete constituents are finite materials that can be easily depleted due to the increasing demand for concrete. A considerable amount of waste glass (WG) that usually constitutes a nuisance to the environment is now processed as fine aggregate and cement replacement used in concrete. This is an attempt to reduce cost, improve properties and reduce the total embodied carbon in concrete manufacturing of approximately 8% of the world's CO2 emissions. Studies have shown that WG constitutes a large amount of silicon oxide and relative proportions of calcium and aluminium oxides. This shows that WG can be regarded as pozzolan when it is finely grounded into powder. It is important to examine the concrete microstructure and durability properties to ascertain the effectiveness of WG powder as a cement replacement material in concrete. This paper reviews the microstructure and durability properties of concrete that contains WG powder. It summarises existing knowledge of the successful use of WG powder in concrete.
