The Use of Supersulfated Cement(SSC)in Mass Concrete

摘要

This paper isfocused on the use of Supersulfated Cement (SSC) in mass concrete. The physicalproperties and mechanicalproperty was tested. Contrast with the common cement, this paper studied the temperature rise of hydration and the heat of hydration to obtain the advantage of SSC, which will provide the basis for the use of SSC in mass concrete.The micro properties were tested through Scanning Electron Microscope (SEM). The test shows that the SSC shows better workingperformance than ordinary cement. The compressive strength of SSC under standard curing condition is higher than that under room curing condition. The compressive strength of SSC is increasing with time and the rate of increasing is decreasing. The temperature rise of hydration of SSC are lower than that of ordinary cement. Different with the ordinary cement, the main hydrated products of SSC areettringite and scalycalcium silicate hydrate.
