Sažetak
In this paper, the potential benefits offered by calcium sulfoaluminate cement (CSA) production from industrial wastes or by-products already present in Republic of Croatia have been addressed. A variety of industrial wastes, namely phosphogypsum (PG), coal bottom ash (BA) and electric arc furnace slag (EAFS) were used as raw materials to provide additional environmental advantages in production of CSA. Mass fraction of Ye’elimite, the principal hydraulic mineral in the prepared CSA was determined by quantitative X-ray powder diffraction. Calculated phase composition based on 18 sub-systems of five-component assemblages, each containing five clinker phases, showed promising results. The hydration behavior of CSA clinkers was investigated by calorimetric and Vickers hardness tests. In conclusion, CSA production offers an alternative and feasible method of industrial waste minimization.
