Abstract

The cement industries worldwide are currently trying to find alternative cementitious materials for reducing the environmental impact and promoting sustainability. Among them, one is waste glass utilization. A major effort has been made to develop waste glass as aggregates in the concrete industry without complicated procedure. Applications of waste glass to the concrete aggregates are partly limited and often not successful due to the problem of alkali-silica reaction (ASR) between a larger amount of alkali and reactive silica in the waste glass resulted in severely aggravating durability of concrete. Possible method of reusing waste glass has been also developed on the utilization as supplementary cementitious material (SCM) including the economic and environmental concerns of waste glass utilization, if it is ground small enough, with suppressing the ASR expansion by pozzolanic activity of amorphous silica in waste glass powder. Many results of previous researchers as SCM of grounded waste glass are evaluated in this review.
