The hydration of β‐dicalcium silicate was followed at a fixed w/c ratio of 0.45 and at 10° to 40°C by analyzing the liquid phase in the paste, by determining free lime and combined water, and by electron microscopy. The reaction proceeded from the induction period through a propagative surface nucleation‐growth of the CSH stage and an Overall penetration reaction Sw; the kinetics of these stages are discussed.
