Waterproof structure of pavement of concrete floor system, the waterproofing pavement was administered with respect to operation methodological null floor system

摘要

PROBLEM TO BE SOLVED: To provide a structure suitable for a waterproof pavement of a concrete floor slab.;SOLUTION: A primer layer 1, a waterproof layer 2 and an adhesion layer 3 are provided on the concrete floor slab. The adhesion layer 3, which is a layer formed by using a methacryl resin as a base compound, is formed by coating a surface of the waterproof layer 2 with 0.7-1.1 kg of the methacryl resin per 1 m²; granular rigid aggregate is sprayed on the whole surface of the adhesion layer; and additionally, an asphalt emulsion is sprayed thereon. The rigid aggregate with a particle diameter of 0.5-2.0 mm occupies 80 wt.% or more of the whole aggregate. In a particle of the rigid aggregate, specific gravity is 2 or more; Mohs hardness is 7 or more; and an abrasion loss specified in JIS A 1121 is 20% or less. The particles of the rigid aggregate are sprayed on the surface of the adhesion layer in such a manner that an effective adhesion amount is in the range of 2.5-3.0 kg per 1 m².;COPYRIGHT: (C)2011,JPO&INPIT
