The effect of stabilizing agents on the hydration rate of β-C2S

Small quantities (<2%) of various metal oxides are incorporated into the lattice of β-C₂S during the high temperature preparation. The effect which these stabilizers have on the hydration rate is examined. A model involving the charge/radius ratio of the metal ion is developed to explain altered hydration rates. This charge/ radius ratio model also proves useful in describing the crystal-chemical stabilization of β-C₂S. In addition, the solubility of Cr₂O₃ in β-C₂S is determined by a novel differential thermal analysis technique.
