A complex of physical and chemical methods of analysis has been employed to investigate the effect of fine-grain silica, obtained from copper-nickel smelter slag, on hardening and phase composition of magnesia oxychloride binder. In the composition of the magnesia cement, modified by the addition of silica, along with the main products of hardening binder found oxyhydrochloride compound of magnesium and silicon, which contributes to the improvement of water resistance of cement stone. The average composition of the magnesia binder, modified by the addition of silica, is reported.
