Abstract

Dicalcium silicate (Ca2SiO4) isan importantcomponent of cement. The compound ofCa2-xSrxSiO4 can be formed if the Sr containing precursorsare used to synthesize the cement. The presence of Sr may alter the hydrationof the product. The hydration chemistry ofCa2-xSrxSiO4 compounds is reported. The hydration of Ca2-xSrxSiO4was conducted uder nitrogen atmosphere for about 6 months. The dry samples were characterized usingXRD, FTIR, TGA-DSC, andSEM-EDXmethods. It is confirmed that the hydration ofCa2-xSrxSiO4produces mainlyCa3Si2O7.3H2O and Ca(OH)2. However, the Sr doped Ca3Si2O7.3H2O andCa(OH)2 are possibly formed.The compound of CaCO3,as the result ofinteractions between Ca(OH)2 and atmospheric CO2gas during the sample handling,is also observed.
