Abstract
Description
More particularly, the present invention relates to a liquid type concrete waterproofing agent capable of imparting water resistance to a concrete structure itself by mixing concrete into a concrete mixer, a method for manufacturing the same, and a construction method using the same.
Concrete is composed of aggregates such as water, cement, sand, and gravel, and is used to form building structures such as buildings, bridges, and tunnels by using a hydration reaction that hardens by reacting cement and water.
The concrete structure is divided into the underground layer buried in the ground and the surface layer exposed to the air. The underground layer is always in contact with water and the durability may be lowered due to repeated shrinkage and expansion due to the temperature change. The durability of concrete is especially affected by moisture, and water acts as a medium to deteriorate concrete. Dissolved sulfate, nitrate, carbonate, and acid rain can accelerate the damage of concrete structure.
It is inevitable that voids are formed inside the concrete in the hydration reaction, which is the process of curing the concrete, and this internal void becomes the path through which the water penetrates into the concrete structure. Water penetration through the internal pores can cause microcracks, which can deteriorate the waterproofing performance of the concrete, and can also significantly affect the life of the concrete structure while corroding the rebar.
As concrete methods for imparting waterproofness to concrete, there are a method of forming a waterproof film on a concrete surface, a method of penetrating a waterproofing agent to a certain depth, a method of preventing pores and cracks in a concrete, and the like, Is called concrete waterproofing. Spherical waterproofing is implemented by a method of reducing the amount of water to reduce the generation of internal voids, a method of filling the internal voids with fine particles, a method of preventing moisture penetration by mixing water repellent materials, and the like.
A prior art document relating to a concrete ballast waterproofing agent is Korean Patent Publication No. 2009-100885.

However, the sphere water repellent agent disclosed in the above literature is limited only by the water-repellent performance by the water-repellent component, and thus has a limitation in improving the waterproof performance. Therefore, there is a great need for the development of a new liquid spherical water repellent agent that exhibits waterproof performance by various mechanisms and is excellent in workability.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method for producing a water-repellent agent for liquid spheres, which is improved in workability while exhibiting waterproof performance by various mechanisms.

The method for producing a liquid-filled concrete waterproofing agent according to the present invention comprises 100 parts by weight of water, 15 to 20 parts by weight of stearic acid amide, 15 to 20 parts by weight of oleic acid, 40 to 50 parts by weight of sulfonated naphthalene formaldehyde condensate, 2 parts by weight of an aqueous ammonia solution, 5 to 10 parts by weight of an aqueous ammonia solution and 0.5 to 1 part by weight of a surfactant, and stirring the mixture at a temperature of 80 to 90 DEG C for 15 minutes to prepare a water- 2 to 3 parts by weight of silica fume, 20 to 30 parts by weight of active silica, 3 to 5 parts by weight of diatomaceous earth and 10 to 15 parts by weight of water-soluble latex were mixed and stirred at 70 to 90 ° C for 15 minutes to obtain inorganic particle- Mixing the water-repellency-imparting mixed solution and the inorganic particle-filled dispersion solution at a weight ratio of 1: 0.5 to 1: 0.8, stirring the mixture at a temperature of 70 to 80 DEG C for 10 minutes, A third step of preparing a base waterproof base solution, mixing 1 to 2 parts by weight of sodium lauryl sulfate and 1 to 2 parts by weight of sodium benzoate into 100 parts by weight of the base water-repellent base solution and heating at 70 to 80 캜 for 10 minutes And a fourth step of preparing a concrete waterproofing liquid by stirring.
Fig. 1 is a view showing a process for producing the liquid-phase-containing water repellent agent of the present invention in order. 1, the method for manufacturing a liquid-repellent water repellent agent of the present invention comprises the steps of preparing a water repellency-imparting mixed solution (S1), preparing an inorganic particle-filled dispersion solution (S2) A step S4 of producing a waterproofing liquid and a step S5 of mixing the hydrogel particles. It is preferable that the above-mentioned steps proceed sequentially, and each step functions to mix the components exhibiting waterproof performance into components of the concrete waterproofing agent by different mechanisms.
The first step is the preparation of the water repellent admixture solution. The water-repellent mixing solution contains a fatty acid salt as a basic water-repellent component, and contains a fluidizing agent and a surfactant. The water-repellent component may be produced by reacting stearic acid amide and oleic acid with an aqueous ammonia solution, and the stearic acid amide may specifically be N, N'-methylenebisstearic acid amide. Stearic acid amide and aqueous ammonia solution of oleic acid have the function of pushing the moisture penetrating into the concrete by including the hydrophobic group in the fatty acid salts such as stearate and olive phosphate. The stearic acid amide is preferably 15 to 20 parts by weight based on 100 parts by weight of water as a solvent and 15 to 20 parts by weight relative to 100 parts by weight of water. If the amounts of stearic acid amide and oleic acid are less than 15 parts by weight each, the water repellency is deteriorated excessively, and if it exceeds 20 parts by weight, the strength of the concrete may be lowered. The amount of the ammonia aqueous solution is preferably 5 to 10 parts by weight relative to 100 parts by weight of water as a solvent. If the amount of the aqueous ammonia solution is less than 5 parts by weight, unreacted stearic acid and oleic acid may be present. If the amount is more than 10 parts by weight, corrosion of aggregates and the like may occur due to ammonia.
The water repellent-imparting mixed solution may further contain a fluidizing agent and a surfactant. The fluidizing agent may be a sulphonated melamine formaldehyde condensate (SM), sodium naphthionate, or the like. The fluidizing agent is included in the concrete composition to lower the viscosity, and it is possible to reduce the mixing amount of the minimum amount of water for workability and thus to inhibit the formation of pores in the concrete. The sulfonated naphthalene formaldehyde condensate, which is a fluidizing agent, is preferably mixed at 40 to 50 parts by weight with respect to 100 parts by weight of water as a solvent. When the amount is less than 40 parts by weight, the effect of imparting fluidity is excessively small. Can be degraded. Another fluidizing agent, sodium naphthionate, has the function of functioning as a fluidizing agent and a function of forming a fatty acid salt by reacting a part of oleic acid with stearic acid amide. The addition of sodium naphthonate further improves water repellency. The amount of sodium naphthoate to be added is preferably 1 to 2 parts by weight relative to 100 parts by weight of water as a solvent. When the content of sodium naphthonate is less than 1 part by weight, the fatty acid salt forming effect is less likely to be produced, and when it exceeds 2 parts by weight, rebar corrosion due to the sodium component may occur. The surfactant is required for the dispersion of stearic acid amide and oleic acid. Specifically, the surfactant may be an alkyl benzene sulfonate. The amount thereof is preferably 0.5 to 1 part by weight based on 100 parts by weight of water as a solvent. The water-repellent mixing solution is preferably prepared at 80 to 90 ° C. for 10 to 20 minutes. This temperature condition is favorable for the dissolution of fatty acids such as stearic acid amide and oleic acid.
The second step is the step of preparing the inorganic particle-filled dispersion solution. The inorganic particle-filled dispersion solution contains fine particles such as silica fume, activated silica, diatomaceous earth. These inorganic particles are contained within the concrete structure to fill the internal voids created in the hydration reaction. It is preferable that silica fume, activated silica and diatomaceous earth have different particle sizes, and silica fume is preferably larger in particle size than active silica and diatomaceous earth. When inorganic particles of different particle sizes are mixed, it is more advantageous to fill voids of various sizes. The particle size of the silica fume is preferably in the range of 50 to 300 microns, and the particle size of the active silica and the diatomaceous earth is preferably in the range of 10 to 50 microns. The inorganic particle-filled dispersion solution further comprises a water-soluble latex. The water-soluble latex enhances the viscosity of the inorganic particle-filled dispersion solution, thereby helping the inorganic particles to be more uniformly dispersed in the inorganic particle-filled dispersion solution. As a polymer resin, the concrete forms a fine membrane So as to fundamentally prevent the movement path of the water. The amount of silica fume is preferably 2 to 3 parts by weight, more preferably 20 to 30 parts by weight, and the amount of diatomaceous earth is preferably 3 to 5 parts by weight relative to 100 parts by weight of water as a dispersion liquid. Silica, and diatomaceous earth in consideration of the desired particle size. The amount of the water-soluble latex is preferably 10 to 15 parts by weight. The inorganic particle-filled dispersion liquid is preferably prepared under stirring conditions at a temperature of 70 to 90 DEG C for 10 to 20 minutes.
In the third step, the water repellent-imparting mixed solution prepared in the first step and the inorganic particle-filled dispersing solution prepared in the second step are mixed to prepare a basic waterproof base solution. At this time, the mixing ratio of the water repellency-imparting mixed solution to the inorganic particle-filled dispersion solution is preferably 1: 0.5 to 1: 0.8 by weight. When the mixing ratio of the inorganic particle-filled dispersion solution is less than 1: 0.5, the void filling effect due to the inorganic particles is insufficient and large voids can be formed inside. When the mixing ratio is more than 1: 0.8, The waterproof effect may be insufficient due to the deterioration of the effect. The mixing of the water repellent-imparting mixed solution and the inorganic particle-filled dispersion solution is preferably performed at a temperature of 70 to 80 캜 for 5 to 15 minutes.
The fourth step is to mix the air-entraining agent and the corrosion inhibitor into the concrete waterproofing base solution prepared in the third step to prepare a concrete waterproofing solution. The air entraining agent functions to regulate the viscosity and the air distribution of the concrete mixture by generating fine bubbles. Specifically, sodium lauryl sulfate can be used. The corrosion inhibitor functions to prevent corrosion of reinforcing bars and the like inside the concrete, and sodium benzoate can be used specifically. The amount of the air entraining agent is preferably 1 to 2 parts by weight based on 100 parts by weight of the concrete waterproof base solution, and the amount of the corrosion inhibitor is preferably 1 to 2 parts by weight relative to 100 parts by weight of the specific waterproof base solution. The mixing of the air entraining agent and the anticorrosive agent is preferably carried out at a temperature of 70 to 80 캜 for 5 to 15 minutes.
The fifth step is to mix the hydrogel particles with the spherical water solution prepared in the fourth step. The hydrogel particles are preferably mixed at a ratio of 0.5 to 1 part by weight with respect to 100 parts by weight of the spherical waterproofing solution, and the mixing time of the hydrogel particles is preferably 5 to 15 minutes. When the mixing amount of the hydrogel particles is less than 0.5 part by weight, the waterproof effect by the hydrogel particles is excessively small, and if it exceeds 1 part by weight, the strength may be lowered. The hydrogel particle is a polymer resin particle having a property of absorbing water and expanding, and may be specifically poly-2-hydroxyethylmethacrylate (PHEMA). The hydrogel particles are dispersed in the concrete structure, and when moisture penetrates from the surface, the hydrogel particles expand while absorbing moisture. The hydrogel particles located in the pores of the concrete fill the voids while expanding and function to prevent moisture from penetrating into the interior. Hydrogel particles basically absorb water and expand. However, water absorbed in water is discharged to the outside depending on the concentration of the salt contained in the water. Since there are many kinds of salts in the liquid spherical water repellent agent, the hydrogel particles are present in a state in which the liquid gel precursor is present in the waterproofing agent or concrete composition in a relatively unexpanded state. The hydrogel, which was dispersed in the cured concrete spherical state, functions to prevent water from penetrating any more because it absorbs moisture while filling underground water or rainwater from the outside. The particle size of the hydrogel particles is preferably 5 to 20 microns. If the particle size of the hydrogel particles is less than 5 microns, the preparation is difficult, while if the particle size exceeds 20 microns, dispersion becomes difficult.
The liquid spherical water repellent prepared by the above method can be used to produce concrete or mortar having high waterproofness when mixed with a concrete or mortar composition, including a water repellency imparting material, an inorganic particle filling material, hydrogel particles and the like. These liquid-filled concrete waterproofing agents must be mixed into the concrete or mortar composition prior to casting, and may be mixed into the concrete or mortar composition by in-situ mixing or plant mixing. Field mixing is a method of mixing directly into a mix truck and mixing the liquid spheres with a water repellent agent into the mix truck and mixing them uniformly at high speed for 3 minutes or more. Factory mixing is a method of mixing liquid concrete waterproofing agent in a batcher plant which is a facility for manufacturing a large amount of concrete or mortar composition, and it is a method of mixing 3 to 3.5 kg May be added to the mixed water.
