摘要 |
<p>A gypsum-bonded material contains porous spherical hydrated calcium silicate crystal aggregates having a loosely mixed crystal core with a densely mixed crystal external layer. In a material comprising a gypsum matrix incorporating 2-84 wt.% porous spherical aggregates of hydrated calcium silicate crystals, each aggregate has a core with loosely mixed crystals and an external layer with more densely mixed crystals. Independent claims are also included for the following: (i) processes for production of the above material, in which the aggregates are obtained by hydrothermal synthesis from an aqueous lime suspension and silica; and (ii) a fireproof construction element comprising the above material or a material produced by the above processes.</p> |
