Abstract: Fire represents one of the most severe environmental conditions to which structures may be subjected. The increased use of SCC has raised concerns regarding the behavior of such concretes under elevated temperatures. The study is carried out mechanical characteristics of SCC containing steel slag as fine aggregate exposed to elevated temperature. The temperatures used in the study are 300°C, 600°C, 900°C with an exposure time of 2 hours. The steel slag percentage is varied and SCC is produced. The workability properties of SCC are studied such as Slump flow, T50 and J- ring. It can be said that till 50% steel slag replacement, SCC can be produced. The mechanical properties of SCC such as weight loss, water absorption, compressive strength and volume change. The average difference in weight loss between 300°C and 900°C is 4%.The water absorption increases as the steel slag percentage increases. The effect of temperature is reduced as the steel slag percentage is increased. The volume change at higher temperature is higher and increases as the percentage of steel slag increases.
