Hong Kong Tests Recycled Glass in Concrete
Engineers in Hong Kong have used recycled waste glass in concrete pavers for over 15 years. Their long-term field checks found no internal cracking caused by the reaction between glass and concrete. The findings respond to earlier worries about that reaction.
Context
