<p>PURPOSE:To produce a ceramic building material having a higher material. CONSTITUTION:A mixture consists of the inorg. powder material, inorg. foaming aggregate and reinforcing fiber in the ratio necessary to produce a ceramic lightweight building material. PVA grains having 0.15-1.0mm diameter and >=95mol% degree of saponification are added by 0.1-5.0wt.%, based on the total amt. of the inorg. mixing material, to the mixture and uniformly mixed, water is added to the mixture, and the admixture is shaped, aged with high- temp. steam and cured. The strength of the ceramic building material is increased by controlling the degree of saponification, grain diameter and amt. of the PVA grain.</p> |
