Method and apparatus for producing calcium silicate hydrate

摘要

A method of producing calcium silicate hydrate is disclosed, which comprises: contacting calcareous material with crystalline siliceous material in an aqueous environment under elevated temperature and pressure and for a sufficient time to permit the calcareous material and crystalline siliceous material to react and form calcium silicate hydrate, wherein prior to said reaction, a predetermined quantity of a suspension agent is added to permit said reaction to take place with little or no agitation. The resultant calcium silicate hydrate has a high post reaction solids content of around 35% or higher.
