Due to the fact that steel slags are made at the temperatures up to 1600°C, utilization in concretes with improved properties after the exposure to high temperatures is considered in this paper. An experimental program was designed and carried out to study properties of four steel slag based concrete mixtures with different types of cement pastes prior and after heating up to 800°C. Dolomite based concrete mixture was studied as a reference mixture. The results obtained have shown that residual mechanical properties of concrete made with steel slag aggregate are comparable to the reference dolomite concrete up to the tempera- ture of ca. 550°C, while at higher temperatures, steel slag exhibits mineral transformation followed by unstable volumetric expansion which reflected negatively on the residual properties of slag based concrete mixtures. This expansion become stable if the slag was previously heated up to 1000°C. |
