Quasi-elastic neutron scattering study of the hydration of tricalcium silicate
Quasi-elastic neutron scattering provides a direct measure of the amount of water bound during the hydration of tricalcium silicate, the principal component of Portland cement. This can be used to follow the progress of the reaction as a function of time. To examine the effect of temperature on the process measurements were made on samples held at fixed temperatures ranging from 5 to 40 degrees C. The results show at least three different stages of the hydration reaction. The early stage appears to be controlled by surface reactivity, the late stage by diffusion through the calcium silicate hydrate gel.
