摘要：

The chemical and physical properties of C3S, β‐C2S, a C3S/C2S blend, and portland cement pastes cured at 25°C were investigated. The H2O specific surface areas of the calcium silicate samples follow a common linear relation when plotted against a CIS ratio. The β‐C2S had higher capillary porosity and N2 surface area, resulting from increased mesopore volume at the expense of micropores. All calcium silicate pastes had similar polysilicate content vs time curves, indicating an aging process which is not sensitive to the starting composition of the hydrating calcium silicate. The polysilicate content of portland cement was much lower than that of the corresponding calcium silicate pastes. Strength‐capillary porosity relations for the various systems are discussed.
