摘要: A method for producing hydrous calcium silicates such as xonotlite, tobermorite and the like, which comprises interacting a siliceous material and a calcareous material or a siliceous material, a calcareous material and a small amount of a magnesia material in aqueous slurry to make above 50% by weight of gelation materials at 50*-100*C, rapidly raising the temperature of the gelation slurry to above 160*C continuously with pressurized water of high temperature allowing to stand the slurry at the temperature for a definite time and then continuously discharging the reaction product.
