In Hong Kong, waste glass has become an important component in the municipal solid waste stream, but the recovery rate of waste glass is very low (less than 10%) due to the lack of recycling outlets. Since glass is chemically inert, has high intrinsic strength and low gas permeability, use of recycled glass cullet as a replacement of aggregates in construction is an attractive recycling option. Efforts have been carried out at The Hong Kong Polytechnic University to turn waste glass into a valuable resource in cement-based products, such as architectural cement mortars, concrete paving blocks and self-compacting concrete. The findings of this investigation show encouraging results and opened up several outlets for recycling waste glass in the production of various concrete products.
