Abstract

Concrete normally suffers from low stiffness and poor strain capacity after exposure to high temperatures. This study focused on evaluating the effect of recycled glass (RG) on the residual mechanical properties of self-compacting glass concrete (SCGC) after exposure to elevated temperatures. RG was used to replace fine aggregate at ratios of 0%, 25%, 50%, 75% and 100% by weight. The residual properties were evaluated according to compressive strength, elastic modulus, stress-strain behaviour and strain at pre-load and peak stress. A comparative assessment of different curing conditions on the SCGC was also conducted. The results showed that there were significant decreases in compressive strength, elastic modulus and concrete stiffness of the concrete with increasing temperature. The use of RG had little influence on the elastic modulus at ambient temperature; however, after exposure to 800°C, the mechanical properties of the concrete were greatly enhanced by incorporating RG.
