PROCESS FOR PREPARING CALCIUM SILICATE SHAPED PRODUCT
摘要
<p>A calcium silicate shaped product is produced by forming an aqueous slurry of calcium silicate hydrate obtained by reacting a calcareous source with a siliceous source dispersed in water under heating; molding said aqueous slurry and heat-treating said molded product under the condition providing the equations (I) and (II); 100</= theta xT (I) 50</= theta </=300 (II) wherein theta represents a temperature of the inner part of the molded product ( DEG C.) and T represents a time (hour) and providing a percent water loss of the treated molded product of less than 25 wt. %, before drying or steam-curing and drying the molded product.</p>
