Abstract

PURPOSE: To effectively prevent check to the hardening of cement by woody materials, by treating the woody materials with at least one side of bivalent and trivalent metallic salts with vitriolic radicals and monovalent metallic salts with vitriolic radicals.
CONSTITUTION: Woody materials are treated by immersing the materials in at least one side of the water solutions of bivalent and trivalent metallic salts with vitriolic radicals and by immersing the materials in a water solution of monovalent metallic salts with vitriolic radicals. Said order of immersion may be reversed. The woody materials are treated in this manner, cement, water and additives, such as, reinforcing materials, etc. as necessary are added and mixed, and the materials are molded by means of known methods and cured, thus forming woody cement boards. The strength of the woody cement boards obtained in this way is extremely large because the hardening of cement is not checked.
