FAST-CURING FLOOR MATERIAL AND HARD FLOOR

摘要

PROBLEM TO BE SOLVED: To provide a cement-system thin-coating-type of a fast-curing floor material capable of achieving a desired fluidity with a simple work at a construction site regardless of a temperature during the construction.;SOLUTION: A floor material is made according to a specification which specifies three materials including a fast-curing cement for a powder part, acrylic emulsion for a liquid part, and a retardant to be mixed. For manufacturing of the floor material, an addition amount of the retardant is controlled at the construction site, and determined to suit a construction temperature based on a correlation data between temperatures during a construction time to mix the materials and corresponding addition amounts obtained from a blending design to suitably control a fluidity of the floor material, an amount of the retardant suitable to the construction temperature is determined, and the materials are mixed at the construction site.;COPYRIGHT: (C)2015,JPO&INPIT
