The approach to equilibrium of mixtures of CaO, A1₂O₃, and SiO₂ heated to various temperatures
… anorthite-mullite-cristobalite and the anorthite-gehlenite-corundum compatibility triangles were fired to 1400° C. The effect on equilibrium of different raw materials used to form the compositions was also studied. Based on the results of the present investigation the following conclusions seem …

Examination of hydrated and accelerated carbonated cement-heavy metal mixtures
… in the pastes of C3A, C4AF, Ci2A? and CA were gehlenite hydrate, calcium carboaluminate, C4AH X and hydrogarnet. Heavy metals, especially Zn 2+ , inhibited the formation of hydrogarnet and promoted the conversion of C-A-H to calcium carboaluminate and calcium carbonate. In the presence of …
