Abstract	In this paper, thermal expansion properties of hydraulic cement paste are studied. Two kinds of heat systems are included in the research: one is heating from 20°C to 600°C directly, another is heating from 20°C to 600°C after several thermal cycles which range from 20°C to 180°C. The results show that thermal expansion curve increases at the initial stage and then decreases with the temperature increasing in the both two heat systems. But the temperature of the former heat system at which the thermal expansion ratio reaches maximum is 70°C lower than that of the latter. That means that the thermal cycle decreases the temperature to reach the maximum thermal expansion. The mechanism of thermal expansion of hydraulic cement paste is also researched with DSC/TG and XRD methods.
