A Review on Recycling of Waste Glass in Construction Industry

The utilization of many industrial byproducts in the construction industry is now well-developed as it helps in improving the sustainability in two ways. First, reuse of the materials which otherwise will burden the environment and will be occupying scarce land resource. Second, it minimizes the degradation of land and the environment as a result of comparatively less digging. Quantities of waste glass have been on the rise in recent years due to an increase in industrialization and the rapid improvement in the standard of living. Unfortunately, the majority of waste glass is not being recycled but rather abandoned, and is therefore the cause of certain serious problems such as the waste of natural resources and environmental pollution. Thus, efforts have been made during the last decade on exploring the possibility of reusing waste glass as a construction material. Waste glasses can be used as raw materials for cement production as siliceous sources. Ground glass powders exhibit very good pozzolanic reactivity and can be used as cement replacement. The crushed glasses can also use as aggregates for Portland cement concrete. The present paper reviewed the different studies regarding use of waste glass in concrete and finds their effect on the properties of concrete.
