Reaction of Portland cement clinker with gaseous SO2 to form alite-ye'elimite clinker
https://orcid.org/0000-0001-8632-2112
Abstract In this paper, an innovative method was proposed to synthesize an alite-ye'elimite clinker by adopting a secondary heat treatment step in a different sintering atmosphere after a traditional Portland cement (PC) clinker has been heated up at 1450 °C. It was found that a pure gaseous SO2 or mixed gas containing the gaseous SO2 used facilitated the decomposition of C3S and the consumption of C3A in the PC clinker. Simultaneously, anhydrite (CaSO4), ye'elimite (3CaO·3Al2O3·CaSO4, C4A3$) and ternesite (4CaO·2SiO2·CaSO4, C5S2$) coexisted in the alite-ye'elimite clinker, resulting from gas-solid reactions during sintering. The experimental results also showed that the compressive strength of the synthesized alite-ye'elimite cement was higher than that of PC. Moreover, its setting times were shorter than that of PC.
