Description
The influence of heat curing was considered which it has on the hydration and silicate structure of cement paste and silica fume paste. The influences were discussed from the perspectives of cement hydration required by the Rietveld method using powder X-ray diffraction（XRD）, silica fume hydration by the selective dissolution method and silicate-chain polymerization of hydrate calcium silicate（C-S-H）by the trimethylsilyl（TMS）derivatization method. The influence of the hydration reaction and silicate structure on a heat curing history was not concerned with the heat curing pattern, but the reaction of cement and silica fume promoted it. In the case of 90℃ highest temperature, the silicate structure more than the trimer of C-S-H increased with cement paste. It checked that more than 90mass％ consisted of polymers more than a dimer with silica fume paste.
