In recent years, with increasing environmental pressure to reuse, reduce or recycle as much wastes as possible cross the world, the concrete industry has implemented a number of recycling methods to achieve this goal. One of the oldest construction materials that have been utilised by human being in many projects for decades is glass. As a result a large volume of post-consumer glass is being generated by people and discarded on a regular basis which is likely to increase considerably in the

... ure. Thus, many studies have been done to investigate different recycling techniques and the potential use of waste glass (WG) as aggregates in making concrete. For the present study, four concrete mixtures in total with varying crushed waste glass as a partial replacement for natural fine aggregate at 0%, 15%, 30% and 60% were prepared. The water/cement ratio of 0.5 was kept constant for all concrete mixtures. The properties investigated were aggregates particle size distribution, consistency, dry density, compressive strength and total water absorption of concrete containing varying amounts of WG. According to the results obtained with increasing WG content in concrete the compressive strength decreased compared with the control concrete. The minimum 28 days strength obtained at 60% WG. However, with appropriate mix design utilisation of WG in concrete production especially in low-strength applications is possible. However, before such concrete can be considered safe for general use in concrete, long-term concrete engineering tests need to be carried out.
