A COMPOSITE OF CEMENT MORTAR WITH WATER PROOFING PROPERTIES USING COPOLYMERS AND ACTIVATED SILICA MINERALS

摘要

The present invention relates to a functional waterproof cement mortar for finishing with excellent waterproofing and blocking of harmful ions, 30-50 parts by weight of cement, 20-40 parts by weight of silica sand (60-100 mesh), 10-20 parts by weight of slaked lime ( Diatomaceous earth with calcium oxide content of not less than 85% by weight and particle size of 325 mesh or less), and activated once at 550 to 650 degrees Celsius (silica content of 85% or more by weight and particle size of 325 mesh or less) 15-25 parts by weight, 7-12 parts by weight of a silofluoride compound, 1-2 parts by weight of stearic acid salt, which is a waterproofing material, and an additive such as a conventional antifoaming agent, a thickener, and a dispersant within 3 parts by weight. The ratio of acryl vinyl acetate copolymerized emulsion, anionic acrylic styrene copolymerized emulsion, and vinyl acetate copolymerized emulsion, which is an elastomeric polymer resin having parts by weight and elastic properties, is in a weight ratio of 2-5: 1-3. It is characterized in that it is mixed with 20 to 40 parts by weight of the liquid resin composition mixed in a ratio of: 3-5, and the functional cement mortar for finishing of the present invention exhibits the same or more waterproof than the conventional waterproof mortar By preventing the penetration of sulfurous acid, nitrous acid, carbon dioxide and the like has an excellent effect of preventing the deterioration of the concrete structure of the cement material.;Elastomer, Activated Silicate, Hazardous Ions, Calcium Silicate, Waterproof
