The hydraulic property constituent and the hydraulic property mortar and the concrete floor construction

摘要

PROBLEM TO BE SOLVED: To provide a hydraulic composition which has excellent fast hardening properties in order to easily and surely execute the shaping/repair of the surface of a hardened mortar body, which is formed by executing hydraulic mortar and which enables a person to walk softly, and which composition is hardened slowly after the hardening is started and allows the surface of the hardened mortar body to keep moderate water retentivity during that time and to provide the hydraulic mortar, and a concrete floor structure formed by using the hydraulic composition and the hydraulic mortar.;SOLUTION: The hydraulic composition comprises: a hydraulic component composed of alumina cement, portland cement and gypsum; potassium hydroxide fine powder; and fly ash fine powder.;COPYRIGHT: (C)2010,JPO&INPIT
