Failure of Concrete at High Temperatures - The Influence of the Type of Cement

Experimental work verifies behavior of concrete with various types of cement and aggregate when exposed to high temperatures. Concrete samples differed in the aggregate used (two modes - basalt aggregates, lightweight aggregates), combined with four types of cement (CEM I 42.5 R – Mokrá Czech Republic, CEM II/B-M (S-LL) 32.5 R – Mokrá Czech Republic, CEM II/B-S 32.5 R – Cemex Czech Republic, CEM III/B 32.5 N-SV – Cemex Czech Republic). Properties were determined before and after thermal loading. The aim of the presented experiments was to verify behavior of different types of cement in concrete at high temperatures and the effect of various types of cement for subsequent damage concrete samples after exposure to high temperatures.
