Sažetak
This paper presents an experimental research on the performance of high-strength self-compacting concrete (SCC) with different mineral additives after exposure to high temperature of up to 600°C. For this purpose, four SCC mixtures were studied: one reference and three mixtures where the Portland cement was replaced with mineral additive (fly ash, metakaolin and limestone) in certain proportions. After natural cooling in the furnace, compressive strength and static modulus of elasticity were determined and compared to results obtained from other studies and those provided in EN 1992-1-2 and EN 1994-1-2 for normal-vibrated concrete. Additionally, in order to characterize the damage of the specimens caused by high temperatures, AE parameters during compression test of heated and unheated specimens were also obtained.
