Quasi-elastic neutron scattering experiments were carried out to evaluate the hydration rate of tricalcium silicate (Ca3SiO5). Furthermore, in the early hydration period, a variation in surface roughness of Ca3SiO5 was observed in nano-scale by the small-angle neutron scattering. From these results, it was found that the hydration rate of Ca3SiO5 is suppressed when the surface of Ca3SiO5 becomes rough through the creation of hydration products C-S-H gel and Ca(OH)2, and this roughness is associated with changes in the Ca3SiO5 hydration rate.
