Strength development of concrete made with recycled glass aggregates subjected to frost curing conditions

An experimental investigation was undertaken to study whether the strength behavior of concrete made with glass aggregate differed significantly from that made with natural aggregates when concretes cured in low temperatures. The aim of the research work presented is to examine the strength behavior of glass concrete when cured under freezing conditions at -15°C and -10°C. The results showed that when glass concrete is cured at low curing temperature, the 28 day compressive strength is higher than control concrete. Glass concrete that had been cured at low temperatures and subsequently allowed normal curing recovered 100% of its strength while the recovery for control concrete was of about 50%. These findings suggest that concrete made with recycled glass could have an important application, on cold temperature concreting
