Abstract :In this study, lightweight concrete was investigated by using perlite (Pe), pumice (Pu), and waste rubber aggregates (R). The changes in compressive strength of lightweight concrete were investigated, while ultrasonic pulse velocity and density properties were compared after high-temperature exposure (300, 500 ℃). In this context, 11 different types of mixtures were produced. Combinations were formed by keeping the w/c ratio constant. As a result of the experiments, increases in compressive strength were determined at 300 ℃ in general. The compressive strengths of concretes produced using waste rubber aggregates were lower than concretes using pumice and perlite aggregates. It was determined that concrete made using waste rubber exhibited more ductile fracture during compression loading.
