ANTI-SALTDAMAGE COATING FILM COMPOSITION OF WATERPROOF MATERIALS USING FLY ASH, THE COATING METHOD THEREOF, AND THE MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A composition for salt damage resistant waterproofing agents has excellent waterproof properties anti-corrosion performance by including one-component waterproofing agents, fly ash and bipolar inorganic salt, thereby being applicable to the concrete structure located in an area damaged by salt water or a corrosive environment. CONSTITUTION: A composition for salt damage resistant waterproofing agents comprises 12-22 parts by weight of water, 45-55 parts by weight of fly ash, 0.1-1.5 parts by weight of dispersing agents, 0.08-3.0 parts by weight of antifoaming agents, 0.5-3.0 parts by weight of titanium pigment, 1-5 parts by weight of tannin as antioxidants, 0.2-3.0 parts by weight of fumed silica, 0.01-0.13 parts by weight of viscosity increasing agents, 2-7 parts by weight of calcium nitrite as bipolar inorganic salt and 0.5-1.8 parts by weight of sodium nitrite based on 35-45 parts by weight of one-component waterproofing agents. A manufacturing method of the composition for salt damage resistant waterproofing agents comprises the following steps. One-component waterproofing agent is manufactured (S1). A first composition is manufactured by adding water, fly ash, dispersing agents, antifoaming agents, titanium pigment, tannin as antioxidants, fumed silica and viscosity increasing agents in the one-component waterproofing agents (S2). A second composition is manufactured by adding sodium nitrite and calcium nitrite as bipolar inorganic salt in the first composition.
