The use of glass as a cement, filler aggregate and sand substitute for concrete construction is discussed. The main barriers to recycling glass cullet makes it difficult to judge the suitability and correct approach of its use. The influence of glass on concrete performance in the fresh and hardened states is determined by the glass particle size, type, contaminants and characteristics. Powdered glass does not pose a threat to the alkali-silica reaction (ASR) performance and thus is safe to use as a filler in concrete.
