Method for Constructing Concrete Using Penetrating Concrete Water-Repellent Material And Surface Waterproof Admixture

摘要

The present invention is a concrete specification method comprising the step of applying a penetration preventing member and the surface absorption type concrete waterproofing agent relates to . ; specifically, the anti- penetration type concrete surface using a hydrophobic absorbent material is a hydrophobic silane silane , water glass , and a solvent as a concrete surface absorption type penetration preventing member comprises a penetration depth of at least 2mm , in absorbing capacity (water absorption coefficient ratio, the standard state ) 0.5 below, the water permeability ( permeability ratio) of 0.1 or less, chloride ion penetration resistance performance of 2mm or more, prevent the absorption of water contact angle of 130 degree to have more than the material.
