| titleOfInvention | Water inseparable polymer cement mortar and its mixer and concrete structure repair and reinforcement method using the same |
| abstract | The present invention is a mortar material in repairing and reinforcing concrete structures, while maintaining the required characteristics of fast hardness, material inseparability and high fluidity, while improving physical properties such as compressive strength to improve long-term durability and strengthen adhesion strength Water inseparable polymer cement mortar and repair of concrete structures using the same to maintain the effect for a long time, and to have advantages such as material segregation resistance even in water due to excellent material inseparability, excellent fillability, workability and eco-friendliness, etc. The purpose is to provide a reinforcement method. In addition, the present invention can promote the mixing of the inseparable polymer cement mortar in the water inseparable before/after loading even with the staggered input of the underwater inseparable polymer cement mortar to pursue the homogenization of the physical properties, It is another object to provide a mixer for an in-water inseparable polymer cement mortar which can be continued without interruption. The water inseparable polymer cement mortar according to the present invention for achieving the above object is 100 parts by weight of cement, 12.5 to 50 parts by weight of fine aggregate, 0.375 to 3.75 parts by weight of calcium armino ferritic expanding agent, alkylarylsulfonate and alkylammonium salt 0.0375 to 0.125 parts by weight of a powdery thickener containing, 0.0125 to 0.075 parts by weight of a polycarboxylic acid water reducing agent, 0.0025 to 0.025 parts by weight of a silicone antifoaming agent, 0.0005 to 0.025 parts by weight of a polyester antifoaming agent, aluminum powder, nitrogen gas foaming material, peroxide material 0.00025 to 0.0015 parts by weight of a gas foaming material consisting of any one of Ti[OCH(Cl 3 ) 2 ] 4 and (CH 3 ) 2 CHOH 90 parts by weight of an ultra-fine particle titanium dioxide sol prepared by a weight ratio of 1:1; 70 parts by weight of a silica sol prepared by using C 8 H 20 O 4 Si, (CH 3 )CHOH in a 1:1 weight ratio; Zn(C 2 H 3 O 2 ) 2 15 parts by weight of zinc oxide sol; 100 parts by weight of a cement mixture comprising 2 parts by weight of at least one metal ion selected from Ag, Zn, and Cu; Based on 100 parts by weight of the cement mixture, 40 to 64% by weight of methyl methacrylate resin, 20 to 24% by weight of butyl acrylate resin, 1 to 3% by weight of nony phenol, 10 parts by weight of a waterproofing agent composition comprising 1 to 3% by weight of a high fluidizer and 14 to 30% by weight of an additive; Based on 100 parts by weight of the cement mixture, 25 to 30% by weight of a methyl methacrylate (Methyl Methacrylate) resin; 25-30 wt% of polypropylene glycol acrylate resin; 5-10 wt% of Butyl Acrylate resin; 4-5 wt% of polyoxypropylene glycerol triether; lithium silicate 0.1 to 1% by weight; 1-2% by weight of surfactant; 1 to 2 wt% of a polycarboxylic acid-based fluidizing agent; 5 parts by weight of a finishing material composed of 30 to 38% by weight of water; With respect to 100 parts by weight of the cement mixture, 5 parts by weight of a coating film is added and mixed, and the coating film is a polyethylene terephthalate (PET) film having a constant length and width; It consists of an emulsion that is silkscreen printed on the film, the PET film has a thickness of 125 μm, and the emulsion is 100 parts by weight of UM resin, 40 parts by weight of zinc oxide (ZnO), 30 parts by weight of a white solidifying agent parts, 2 parts by weight of a water reducing agent, 1 part by weight of an antifoaming agent, and 1 part by weight of a dispersing agent. In addition, in the underwater inseparable polymer cement mortar mixer according to the present invention for achieving the above object, an input hopper is installed on one side of the cover, a discharge chute is installed under the main wall of the mixing barrel, and the bottom center of the mixing barrel is provided with a mixing vane, and a mixing machine for inseparable polymer cement mortar provided with a driving means for the mixing vane at the bottom of the mixing cylinder; An upper driving means is installed in the center of the cover, and an upper stirring vane is installed on the output shaft of the drive means passing through the center of the plane of the cover. And, the concrete structure repair and reinforcement method using an underwater inseparable polymer cement mortar according to the present invention for achieving the above object comprises the steps of chipping the deterioration part of the target structure (S 1); removing the rust of the reinforcing bar in the deteriorated area (S 2); High-pressure washing the rust removal portion of the reinforcing bar with high-pressure water (S 3); applying a primer to the surface of the deteriorated area of the high-pressure washed structure (S 4); applying a base material to a predetermined thickness and a predetermined shape by mixing an underwater inseparable polymer cement mortar on the primer (S5); It characterized in that it consists of a step (S6) of applying a finishing material on the base material. |
