Abstract
The theoretical basis of the synthesis of calcium hydrocarboaluminates 4CaO×Al2O3×mCO2×11H2O based on the CaCO3 in the aluminate-base system. We construct the isotherm of metastable equilibria in the system CaCO3 – 4CaO×Al2O3×mCO2×11H2O – 3CaO×Al2O3×6H2O – NaAl(OH)4 – NaOH – H2O at 50, 70 and 90°C.
