摘要
PURPOSE: A method for constructing concrete is provided to improve surface strength of the concrete by filling porous concrete pores using a concrete-penetrating surface water-repellent material and to block deterioration factors such as carbon dioxide and salts. ;CONSTITUTION: A method for constructing concrete comprises a step of applying a penetrating concrete water-repellent material and a surface waterproof admixture. The penetrating concrete water-repellent material includes hydrophobic silane, solvent and water glass. The hydrophobic silane has a structure of chemical formula 1. In chemical formula 1, R1, R2, and R3 are C1~C12 alkyl or R1 and R2 are Cl or EtO. The silane is selected from the group consisting of methyltrichlorosilane, methyltrimethoxysilane, phenyltriethoxysilane, and n-octyltriethoxysilane.;COPYRIGHT KIPO 2011
