【Abstract】 The reaction characteristics of CaO-MgO-SiO 2-H 2O system under hydrothermal condition were studied. The results show that, in the CaO-MgO-SiO 2-H 2O system, CaO firstly react with SiO 2 to form calcium silicate hydrates whilst, some of the MgO dissolve in the calcium silicate hydrates, some of the MgO form Mg(OH) 2, some of the MgO react with surplus SiO 2 to form magnesium silicate hydrates. The Presence of MgO can promote the change from tobermorite to xonotlite, without MgO, the temperature of the change increases.更多还原
