Influence of time and temperature on ageing and phases synthesis in the MgO-SiO2-H2O system

► Temperature has a great influence on phases evolution in the MgO-SiO2-H2O system. ► DTA-TGA-EGA is an essential method for evaluating reactions in the MgO-SiO2-H2O system. ► Compounds from MgO-SiO2-H2O system may constitute a bonding phase in basic castables.
