- Description
- The hydration of tricalcium silicate has been studied by small-angle X-ray scattering (SAXS) at different temperatures. The degree of hydration was determined by quantitative X-ray diffraction analysis (QXDA). The kinetics of setting of the pastes is well described by the Johnson-Mehl equation with n=2, suggesting that the scattering objects (hydrated regions) grow by a diffusion controlled mechanism and have a shape of plates of constant thickness. Features of the SAXS curves from samples, in saturated conditions, are consistent with the lamellar model for the structure of the C-S-H gel.
