In this study, the influence of elevated temperature on the physical and mechanical properties of concrete produced by expanded clay aggregate and calcium aluminate cement (CAC) was investigated. For this purpose three different mixture were prepared. First mixture was produced by using ordinary Portland Cement (OPC) and natural aggregate. Second mixture was prepared by OPC and expanded clay aggregate. Third mixture was produced by using CAC and expanded clay aggregate. The water-cement (w/c) ratio used in the mixtures was determined as 0.50. The concrete specimens were heated in an electric furnace up to 200, 400, 600, 800 and 1000 °C and kept at these temperatures for one hour. Two cooling regimes (slow and fast) were used. The residual compressive strength, weight loss, water absorption and porosity ratio and ultrasonic wave velocity values of the specimens were measured. The test results show that exposing to elevated temperatures adversely affected the mechanical and physical properties of the specimens containing OPC and natural aggregate. However, the lightweight concretes produced by expanded clay aggregate demonstrated better performance. Fast cooling (FC) method caused significant strength losses than slow cooling (SC) method.
