Sažetak
In this paper an experimental research work is presented which deals with residual properties of high-strength self-compacting concrete (SCC) after high temperature exposure. Concrete stress-strain behavior was studied after concrete was cooled down from temperatures of 200°C, 400°C and 600°C. Tests were made 7 days and 1 year after high temperature exposure. 7 different mixes of self-compacting concrete was made with different amounts of metakaolin and fly ash. It was found that after 1 year modulus of elasticity of studied concrete had a higher rate of recovery compared to compressive strength.
