Abstract

The effects of different particle size distributions on the real-time hydration of tricalcium silicate cement paste have beenstudied in situ by quasi-elastic neutron scattering. The changing state of water in the cement system is followed as a functionboth of cement hydration time and of temperature for different initial particle size distributions. It is found that the length of theinitial, dormant, induction period, together with the kinetics of hydration product nucleation and growth, depend on thehydration temperature but not on the particle size distribution. However, initial particle size does affect the total amount ofcement hydrated, with finer particle size producing more hydrated cement. Furthermore, the diffusion-limited rate of hydrationat later hydration time is largely determined by the tricalcium silicate initial particle size distribution
