RC FLOOR SLAB STRUCTURE AND REPAIR METHOD FOR INCREASING THICKNESS OF RC FLOOR SLAB

摘要

PROBLEM TO BE SOLVED: To provide a RC floor slab structure in which defective construction of joint is less since the adhesiveness of a RC floor slab to an existing concrete is high, the resistance of the RC floor slab against salt damage is high, the flowability of a rubber latex mortar pavement liquid are high, and the filling property thereof is excellent, and a repair method for increasing the thickness of an RC floor slab which can repair the RC floor slab easily when repairing the RC floor slab.;SOLUTION: In this repair method for an RC floor slab in which a rubber latex mortar layer or a rubber latex concrete layer 12 is formed on the surface of the RC floor slab 10, all the unsound portions of the RC floor slab 10 are chipped off, a rubber plastic layer or a rubber latex concrete layer 12 is laid down at the chipped portions, a drain pavement layer 20 is laid down, and a cement milk in which rubber latex is mixed is filled into the drain pavement layer 20 to form an adhesive layer 18.;COPYRIGHT: (C)2010,JPO&INPIT
