摘要

The stability of sulphoaluminate cement pastes at high temperature was investigated. The results show that the stable hydration products are monosulfoaluminates at 120°C, and they transforms quickly into ettringite during a continuous curing at room temperature. This process leads to quick failure of the structure of the cement pastes. However, the delayed ettringite formation (DEF) does not occur and the structure of the pastes seems to be stable if the heat treatment is carried out at 80°C.
