摘要：
The hydration characteristics of solid solutions of composition 3CaO.xGeO2.(1 - x)SiO2 were investigated at 25-degrees-C by isothermal calorimetry. The compositions hydrated were for x = 0, 0.2, 0.4, 0.6, 0.8, and 1.0. Full hydration was achieved for compositions in which x > 0.2. Both the rate of hydration and the total heat evolved for complete hydration vary with composition. Hydrate compositions were determined, and these also show a compositional dependence. The hydration product for tricalcium germanate has a Ca/Ge ratio near 1.5. Although the hydration products of the solid solution are far more fibrous, their morphologies are reminiscent of that of calcium silicate hydrate.
