MANUFACTURE OF INORGANIC PLATE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an inorganic plate for obtaining the plate having high mechanical strength, a deep protrusion and recess pattern and high frost damage resistance. SOLUTION: Cement slurry containing cement, water and fiber is formed to form a water-containing base 1. A surface layer material 2 having a water content of 7 to 15 wt.% is prepared by mixing the cement with the water. After a surface of the base 1 is roughed, the material 2 is supplied to the surface of the base 1. The base 1 and the material 2 are cured to be hardened. A strength can be developed with the cured material of the base 1. A protrusion and recess pattern can be clearly, effectively formed on the material 2 by using the material 2 having a water content of 7 to 15 wt.%.
