Dec 27 2018 · These aggregates are most commonly bonded with calcium aluminate cements. These cements are composed of either three primary oxides Al2O3-SiO2-CaO or two oxides Al2O3-CaO. Calcia (CaO) is the active phase in these cements and is basic. A silica slag will react with CaO in a refractory and form a corrosion layer of glass.
