For the purpose of effective use of fly-ash, which is a by-product thermal power generation, fly-ash is applied to the precasted concrete products which is substituted by a large amount of fly-ash in recent years.It is heated by the steam curing for the promotion of pozzolanic reaction of fly-ash in genaral.Since the chemical reactions "hydration of cement" and "pozzolanic reaction of fly-ash" occur simultaneously, the reaction analysis of fly-ash cement with steam curing is is extremely complicated.The authors have reported a study of changes in silicate anion structures of hydraulic binders, such as ordinary Portland cement and pulverized blastfurnace slags, during hydration using trimethylsililation (TMS) method.Then, we have tried a detailed reaction analysis of fly ash cement, which has been subjected to heat curing, by considering the chain length distribution of siloxane oligomers constituting the silicate phases of reaction products.
