摘要：

A model is described for predicting the solid and solution chemistry of blended cements for use in equilibrium modelling. A computer program, CEMCHEM, has been written to predict the stable phase assemblage from the composition of the initial cement blend. Solubility models developed for the cement hydrate phases are then used to predict the aqueous solution composition at equilibrium with the cement. Example calculations for mature cement pastes are presented and compared with real pore fluids extracted from aged cements.
