Abstract
A process is described for the formation of shaped hydrated calcium silicate products. The process comprises reacting an aqueous slurry containing a source of calcium hydroxide, perlite as a source of silica, and a soluble calcium salt in the presence of high pressure saturated steam, then adding cooling water followed by subsequent venting of the reactor vessel to ambient pressure. Reinforcing fibers may then be added after which the desired shapes are molded and dried.
