The Use of Recycled Glass in Concrete Technical

Recycled Glass as an Aggregate . Recycled glass is a reactive aggregate that is very prone to the deleterious alkalisilica reaction (ASR). ASR remediation is best accomplished by the use of a pozzolan to replace 20-30% of the cement, or from lithium compounds that work by preferentially forming a nonexpansive gel in the concrete matrix.
