Sažetak
The manufacture of portland cement (PC) consumes huge amount of energy and has a significant CO2 emission. Calcium sulfoaluminate cement (CSAC) is a promising alternative binder to PC due to: a) lower limestone requirement in CSAC ; b) about 200 K lower sintering temperature for CSAC than for PC ; and c) much easier grinding of the fired CSAC. Each of these arguments considerably reduces energy consumption and CO2 emission from cement manufacture. In this paper, the potential benefits offered by CSAC production from industrial wastes or byproducts already present in Republic of Croatia had 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 CSAC. Mass fraction of Klein’s compound (the principal hydraulic mineral) in the prepared CSAC was determined by quantitative X-ray powder diffraction. In conclusion, CSAC production offers an alternative and feasible way of industrial waste minimization.
