Method of manufacturing glazed cement products

摘要

PURPOSE: To produce a glazed cement product without deteriorating the strength even by heating and forming pinholes or causing the scaling off in a glaze layer. ;CONSTITUTION: This method for producing a glazed cement product is to dry a high-strength cement-based hardened product comprising cement, amorphous inorganic powder, an aggregate, etc., then heat the dried cement-based hardened product, replace air in pores of the cement-based hardened product after the heat treatment with steam, etc., subsequently form a glaze layer on the surface thereof and bake the resultant product.;COPYRIGHT: (C)1995,JPO
