METHOD FOR CONSTRUCTING CONCRETE FLOOR STRUCTURE, AND CONCRETE FLOOR STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for constructing a concrete floor structure having accurate horizontal leveling and excellent strength characteristics even in the case of a concrete floor having relatively large irregularities or inclination, and the concrete floor structure produced by the method.;SOLUTION: A method for constructing a concrete floor structure having a layer of hardened self-leveling material slurry body on the top face of a concrete floor having inclination and/or irregularities. The concrete floor having inclination and/or irregularities has a height difference between the lowest part or the most recessed part and the highest part or the most projected part of 10 mm to 50 mm. The surface of the casted self-leveling material slurry has a height higher than the top surface of the highest part or the top surface of the most projected part of the concrete floor by 2 mm to 50 mm. The self-leveling material contains a hydraulic setting component composed of alumina cement, Portland cement, and gypsum.;COPYRIGHT: (C)2013,JPO&INPIT
