), White portland cement, alumina cement, a mixture of water reinforcement (powder) (A), an acrylic copolymer emulsion (Polyacry-late co-polymer emulsion), ionized water Reinforcing reinforcement composed of water, curing agent [Reactive surface Active Agent], antifoaming agent [Non-Silicone Deformen], preservative [In-cam Preservative], preservative [fungicide], fragrance [banana] and aqueous inorganic pigment [Inorganic pigment] The maintenance and reinforcement by mixing the admixture (emulsion) (product B) in the same ratio, so that the reinforcement part of the ground structure is firmly built, so that the life of the repair and the reinforcement structure can be maintained for long time, and the other purpose is the use of acrylic resin Corrosion problems, reinforcement problems, and concrete neutralization problems can be solved.

Recently, due to various deterioration phenomena such as exfoliation, peeling, abnormal crack of reinforced concrete, building structure, compressive strength of concrete and tensile strength of reinforcing steel are reduced, damage of reinforced concrete and furthermore, collapse of steel concrete and corrosion of steel structure The problem of safety accidents due to the destruction of steel structures has been reported in newspapers and on TV, which is becoming a big social problem.

The deterioration factor of concrete and the cause of deterioration are that concrete has strong alkalinity (PH = 12.5), so that corrosion of reinforcing bar does not proceed, but penetration of carbon dioxide gas, acidic substance, chloride (chlorine ion), alkali aggregate reaction , Due to swelling under the weather conditions, the concrete is neutralized, the reinforcing of the rebar proceeds, and the rust is rusted. The swelling of the rust causes the concrete to crack, peeled, fallen, and the local exposure of the corroded rebar. Is broken down and the structure collapses,

In addition, as the structural structures of cement concrete including various civil engineering and construction are neutralized by the penetration of carbon dioxide gas and acid rain, the phenomenon of weakening of the structural structure due to cracking of concrete and corrosion of reinforcing steel is not only infiltration of carbon dioxide gas. In the case of the volcanic pressure of gravel and sand mixed with cement concrete, it is known that the neutralization of cement concrete is accelerated.

In repairing and repairing damaged parts caused by deterioration and corrosion of civil construction structures such as mortar, concrete, and CRC (glass fiber reinforced concrete plate), when repairing and reinforcing generally to exposed concrete structures, general Repair and reinforcement work is carried out with mortar, concrete and epoxy resin, but even if repair and reinforcement of deteriorated concrete structure is not integrated with deterioration damage part and repair reinforcement member, after a certain period of time, the repair and reinforcement part is relaxed and reinforcement function There were a lot of problems that are lost,

In addition, as a concrete example of the conventional reinforcing reinforcement of deteriorated concrete, FRP reinforcing reinforcement composition is a laminated molded product of a low-pressure molding thermosetting resin made of glass fiber as the main reinforcing material. It is suitable for the protection of concrete to prevent the fall of concrete and the deterioration of concrete, but the concrete and the reinforcing reinforcement and physical properties are different, and there is a problem in that the adhesion strength is inferior to a wet surface. As a result of peeling and dropping of concrete due to insufficient coating or deterioration of concrete, it is the most widely used repairing method so far for rebar exposed walls. Can be repaired It does not meet the performance requirements. In particular, there is a problem that the adhesive strength, which is the most important component as compressive strength, flexural strength and repair reinforcement, cannot be maintained.

Recently, water repellent coatings, transparent gloss finishes, anti-slip repellents, sealing agents, crack repairs and waterproofing agents, caulking coatings, reinforcement and waterproofing properties are added to reinforce and strengthen concrete structures such as mortar and concrete such as above. Examples of products that improve the problems in conventional reinforcement construction with admixtures, flame retardants and waterproofing agents, coating and adhering agents, elastic / rustproof / anti-rust coatings, rust treatment agents, and the like are as follows. ,

Examples of transparent gloss finishes for concrete structures and metal structures include the examples of Japanese Patent Application Laid-Open No. 64-9273, which are composed of an aqueous urethane resin, a water medium, a humectant, and an antifoaming agent. Examples of the Japanese Patent Application Laid-Open No. 64-9275, which are composed of a powdery non-slip agent and an acrylic resin, are used as a finishing agent for cement, mortar, concrete, concrete blocks, and GRC plates (glass fiber reinforced concrete plates). Cement structure underlying plasticizer and cement structure underlying plasticizer which is composed of portant cement, titanium oxide and powder acrylic resin, and is coated prior to finishing of the cement, and is an example of Japanese Patent Application Laid-Open No. 1-153583. have.

In addition, examples of Japanese Patent Application Laid-Open No. H1-297485 made of acrylic resin, ammonia, zinc oxide, and plastic alumina are used as sealing agents for connection sealing, sealing of chassis, tile message, PC board message, mortar, and concrete repair. The crack repair and waterproofing agent and the coking agent of concrete, ALC plate, block, etc. are made of acrylic resin, ammonia, zinc oxide, calcium carbonate, ethylene glycol monobutyl ether, and the like. For example, cracks in concrete, iron plates, roofs, and coking coatings include acrylic resins, antifoaming agents, flow humidification components, water media, plasticizers, preservatives, pigment dispersants, and inorganic materials. The example of 2-29467 is mentioned.

In addition, examples of cement admixtures added to cement, concrete, and mortar to provide reinforcement and waterproofing properties include those of Japanese Patent Application Laid-Open No. 2-30648, which is composed of a resin emulsion, a water medium, an antifoaming agent, and a preservative. Examples of high repellents and waterproofing agents include Japanese Patent Application Laid-Open No. Hei 2-43270, which is composed of emulsion, antifoaming agent, ethylene glycol monobutyl ether, caracrylic, benzoisothiazoline, and pigments. Examples of ash, other coating materials, and adherends include those disclosed in Japanese Patent Application Laid-open No. Hei 7-764312 composed of composite resins such as garnet, cement, and acrylic aqueous emulsion.

Further, examples of the elastic coating material, the anti-rust elastic coating material, and the anti-rust coating agent include Japanese Patent Application Laid-Open No. 7-76325 (Korean Patent Publication No. 94-7562), which is composed of an acrylic resin aqueous emulsion, titanium oxide, iron oxide, and calcium carbonate.

It can be.

Such a composition for repairing and reinforcing facility structures, hardware structures, and metal structures of the mortar concrete including various types of civil engineering and construction, is a coating agent having a film coating property on the surface of the structure, or additives and structures added to the mortar. In the cement concrete facility structure, the film formed on the surface delays the penetration of carbonic acid gas into the atmosphere, thereby slowing down the neutralization rate of the highly alkaline cement, thereby maintaining the strength and reinforcing of the facility structure of the cement concrete. It is also known to prevent the corrosion of cement concrete to supplement the service life of cement structures, and to prevent damage by providing corrosion resistance by coatings formed on the surface of steel structures and metal structures.

Mixing with ie 30-35 solids

Solid content is 30-35 by using in (weight ratio)

In the case of exceeding the above, the waterproof performance of the mixed material is improved, but the compressive strength and the flexural strength are decreased, whereas the solid content is 30-35.

In the following cases, the compressive strength and flexural strength were lowered, and the adhesion between the repaired reinforcement and the structure was greatly reduced, which was a major problem of the repaired reinforcement. Used for dispersing resin and water, mixing ratio 0.2

If less, the dispersion effect of acrylic resin and water is lowered and the mixing ratio 0.3

In case of exceeding the above condition, the physical properties (compressive strength and bending strength) of the mixture were found to be inferior by long-term experimental results. When mixing the antifoaming agent [Non-Si licone Deformen] material, it was used as the bubble suppressing agent and the mixing purpose, and the mixing ratio 0.2 In the case of the following, a lot of bubbles are generated during mixing of the mixed materials, and thus the physical properties (compressive strength and flexural strength) decrease, and the mixing ratio 0.3

When the abnormality is exceeded, the physical properties (compressive strength and flexural strength) of the repair reinforcement part are lowered due to the effect of perfect bonding of acrylic resin, cement and aggregate, and the preservative (1) [In-cam Preservative] Used for prevention of alteration of mixed composition
