Japanese Patent JP4432283
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an inorganic cement panel capable of being easily provided with a deep and sharp uneven pattern, generating no filtered water at the time of production and having excellent mechanical strength, and a method for manufacturing the same. SOLUTION: In the inorganic cement panel having a laminated structure consisting of an upper layer and a lower layer, the upper layer comprises a layer formed from inorganic kneaded matter with a water content of 25-50 mass % (with respect to a solid) containing 4-15 mass % of pulp with respect to the solid and the lower layer comprises a layer formed from inorganic kneaded matter with a water content of 150-250 mass % (with respect to the solid).
