Abstract

Some types of industrial waste can be used in concrete as a partial replacement of a cement binder. One such material is fine-ground ceramics, which is a waste produced during brick cutting. The ground ceramic can be used as a pozzolana active material which can improve final properties of concrete. This fine powder was used in this study as a partial replacement of the cement binder up to 60 mass% and its thermal and mechanical properties were studied using the differential scanning calorimetry, thermogravimetry, and thermodilatometry. It was shown that the differential scanning calorimetry is a suitable method for observing thermal changes in concrete samples containing such additives at the microstructural level. In particular, it allows one to investigate the hydration and pozzolanic reaction in the studied concrete. The investigation was performed in the temperature range from 25 °C to 1000 °C.
