Description

TECHNICAL FIELD [0001] The present invention relates to an ocher pavement construction method using an ocher pavement composition having high heat resistance,

The present invention relates to a method of paving loess using a loess pavement composition having high heat resistance and, more particularly, to a method of paving loess pavement using a pavement The present invention relates to a method of packaging a loess pouch using a loess pouch composition having high heat resistance.

Generally, road pavement is a road surface structure that is treated to enhance the road surface and enhance the flatness of the road to facilitate the passage of people and the running of the vehicle, and is a layer structure composed of several layers, and each layer shares each role .

Road pavement is largely classified into reverse osmosis (asphalt) pavement, loess pavement pavement pavement and block pavement depending on the material of the surface layer. In the reverse pavement pavement, the surface layer is made of aggregate such as crushed stone, which is consolidated by asphalt or tar. Packaging, and tar packaging. Currently, it occupies most of the world's roads, and there are many kinds.

Hwangto pavement type pavement is made up of loess pavement in the surface layer. In addition to the ordinary loess pavement pavement in which the loess pavement is inserted or the wire mesh is inserted into the loess pavement, there are reinforcing loess pavement pavement and pristress ocher pavement pavement. Stone blocks, bricks, cement, wood, asphalt, etc. Are laid out on the surface layer.

Meanwhile, in recent years, a packaging method using soil that is environmentally friendly and harmful to human body is being applied to bicycle roads and sidewalks.

However, most of the clay pavement construction methods use pozzolanic materials such as calcium hydroxide, gypsum, limestone, blast furnace slag, fly ash, meta kaolin and silica fume as additives for improving the function of cement or polymer as a main binder have.

Conventional cement and asphalt-based packaging methods require coal or petroleum to produce cement, although they are installed in many fields with very easy operation and low cost. The coal and petroleum resources consumed are consumed in the combustion process Since limestone used as a raw material of cement generates a huge amount of CO ₂ and is composed of CaCO ₃ and is a main raw material for generating CO ₂ gas in the production of cement, there is a problem that the use of cement itself causes environmental pollution.

In other words, CO ₂ gas generated from cement production is one of the main causes of environmental pollution and air pollution.

In addition, the packaging layer of cement or asphalt pavement disrupts the underground ecosystem and the surrounding ecosystem, and it causes artificial blockage of the beneficial elements from the soil to induce rare diseases.

Recently, the awareness of the reduction of cement usage has been spreading internationally based on many environmental problems generated from such cement. For example, the concept of using materials that do not burn is introduced, and various kinds of materials Cement-based materials are emerging. For example, there is a newly developed inorganic binder called a geopolymer or mineral polymer or an inorganic polymer.

However, there are no packaging materials developed by the geopolymer technique yet.

Cement-abatement products and technologies are being developed that take this environmental and industrial awareness into consideration.

For example, Japanese Patent No. 10-438138 discloses a technique of limiting the range of natural soil, cement and solidifying agent composition and inducing excellent physical properties through controlling the particle size, and Japanese Patent Application No. 10-625172 It is stated that soil mixture, cement and aggregate are added to coarse clay or sandy soil with loess component and paper soil sludge, water sludge, composition of stony soil, admixture, swelling agent and repairing agent, have.

However, the above techniques are still techniques that depend on the adhesive strength of the cement, and have little effect on environmental problems.

In addition, Japanese Patent Registration No. 10-504987 discloses a soil strengthening improver composed of an admixture such as fly ash or paper sludge, cement and pigment, slaked lime, and silica fume in soil pavement construction, and Japanese Patent Application No. 10-789877, 10-570958, 10-581227, 10-775360, and the like, are packaging technologies in which the functions are improved through additives and the like in the cement as described above.

It is desirable to use natural soil or eco-friendly material because the soil packing is a wrapping material used in a public walkway, a park, a playground, or an indoors.

In addition, natural damage or destruction for the construction of this packaging material is undesirable because it causes secondary environmental pollution.

In addition, the packaging materials using only soil are often damaged by rainwater, and alternatives to alternative materials for cement are still insufficient.

Physical Properties of Solidified Fine Particles

The admixture is suitable for KSF 2560, and one of naphthalene series, lignin series and polycarboxylic acid series is selected and used.

The admixture may use an appropriate amount of calcium hydroxide (CaO) as an admixture in accordance with the work environment and quality requirements. The mixing ratio of the admixture is 0.1 to 1 part by weight based on 100 parts by weight of the main material.

It is noted that 10 parts by weight of any one of cellulose, eco-friendly resin, geosynthetic fiber, wire mesh and fiber may be added to 100 parts by weight of the main material.

Here, the environmentally friendly resin uses either urethane acrylate resin, UM resin, or environmentally friendly MMA resin.

The ratio of the eco-friendly resin is appropriately adjusted according to the specification of the manufacturer and the pre-use test.

In addition, the water used does not contain substances that affect the ocher pavement such as oil, acid, salts, and organic matter.

If necessary, the reinforcing material may be cellulose, eco-friendly resin, geosynthetic fiber, wire mesh, fiber, or the like.

In addition, when a joint material is required, a sheet material, a compressed styrofoam, or a cut can be used in parallel.

Here, the thickness of the joint material may be replaced with a 6 to 12 mm plywood sheet or compressed styrofoam or by a joint cutting using a cutting machine at the time of curing.

The spacing of the joints is 3 to 5 m depending on the width of the loess pavement.

Based on 100 parts by weight of the main material, 25 to 30% by weight of methyl methacrylate; 25 to 30% by weight of polypropylene glycol acrylate; 5 to 10% by weight of butyl acrylate; 4 to 5% by weight of polyoxypropylene glycerol triether; 0.1 to 1% by weight of lithium silicate; 1 to 2% by weight of a surfactant; 1 to 2% by weight of a polycarboxylic acid-based fluidizing agent; And 10 parts by weight of a main resin composition composed of 30 to 38% by weight of water.

That is, the main resin composition contains 25 to 30% by weight of methyl methacrylate; 25 to 30% by weight of polypropylene glycol acrylate; 5 to 10% by weight of butyl acrylate; 4 to 5% by weight of polyoxypropylene glycerol triether; 0.1 to 1% by weight of lithium silicate; 1 to 2% by weight of a surfactant; 1 to 2% by weight of a polycarboxylic acid-based fluidizing agent; And 30 to 38% by weight of water.

Here, the methyl methacrylate is used for improving ductility and viscoelasticity.

The content of the methyl methacrylate is preferably 25 to 30% by weight.

If the content of methyl methacrylate is more than 30% by weight, the softness and viscoelasticity are improved but the viscosity is lowered, resulting in poor workability and price competitiveness. If the methyl methacrylate content is less than 25% by weight, The effect may be weak.

The polypropylene glycol acrylate is a kind of organic solvent and is preferably used in an amount of 25 to 30% by weight in order to sufficiently improve the polymerizability of the monomer part and lower the content of the solvent.

The reason for limiting the content of butyl acrylate to 5 to 10 wt% is to secure a stable tensile strength of the loess pavement. When 28 days elapses, the strength is 18 MPa, The paleoil pavement was 46.08 MPa at 1 day, 52.14 MPa at 2 days, and 57.88 MPa at 3 days.

In addition, the polyoxypropylene glycerol triether has a strong dispersing and emulsifying power and is excellent in interfacial adsorption, so that it is possible to easily mix the polyurethane raw material.

The amount of the polyoxypropylene glycerol triether is preferably 4 to 5% by weight, and when the polyoxypropylene glycerol triether is less than 4% by weight, the viscosity of the polyoxypropylene glycol ether may be low, If the amount of oxypropylene glycerol triether is larger than 5%, a large amount of bubbles may be generated in the water-soluble resin.

The lithium silicate may penetrate the loess pavement structure and react with calcium hydroxide to form an insoluble calcium silicate hydrate. Lithium silicate makes the structure of the loess pavement more robust and has the effect of improving the durability performance of the loess pavement structure.

The amount of the lithium silicate is preferably 0.1 to 1% by weight.

On the other hand, the reason for limiting the content of the surfactant to 1 to 2% by weight is to promote curing of the loess pavement.

Here, the above surfactant is ethoxylated nonylphenyl.

In addition, the polycarboxylic acid-based fluidizing agent is used for securing fluidity for 120 minutes or more, applying to high strength, high-purity loess pavement, solving slump flow loss, keeping slurry of viscous slurry in loess pouch, freely adjustable, And excellent watertightness, finishability, stable compressive strength, excellent workability and bleeding suppression effect in the case of using a clean cloth with a relatively good mouth shape, mesh and bottom angles, improvement of workability and freezing and thawing resistance by stable airflow, By weight to 2% by weight.

Particularly, it is preferable to use polyethylene glycol sulfonic acid ether or polyethylene glycol methacrylic acid as the polycarboxylic acid-based fluidizing agent.

Particularly, the polycarboxylic acid-based fluidizing agent is used for high-density roughened loess pavement, self-filled loess pavement, large high-rise structure, and 60 n / mm 2 high strength high purity loess pavement.

In addition, the water is preferably purified water, and it is preferably 40 to 45% by weight.

On the other hand, to 100 parts by weight of the main resin composition, 10% by weight of urethane acrylate; 10% by weight of butyl acrylate; 3% by weight of lithium silicate (SiO2); 60% by weight of polymethyl methacrylate; 15% by weight of hydroxyl ethyl methacrylate; And 5 parts by weight of an auxiliary resin composition composed of 2% by weight of sodium silicate (Na2SiO2 .nH2O).

That is, the auxiliary resin composition is composed of urethane acrylate, butyl acrylate, lithium silicate, polymethyl methacrylate, hydroxyethyl methacrylate, and sodium silicate.

Here, the urethane acrylate is a hybride resin having both urethane and acrylate characteristics.

These urethane acrylates are generally prepared by polymerization of a urethane prepolymer with a hydroxyalkyl acrylate.

Urethane prepolymers are formed by the polymerization reaction of polyol and isocyanate, and they are various.

Examples of the hydroxyalkyl acrylate include methyl methacrylate, 2-hydroxyethylmethacrylate, n-butyl acrylate, and the like.

The urethane acrylate was prepared by thermally polymerizing about 20 parts by weight of adipic acid and about 25 parts by weight of isocyanate in a reactor to prepare a urethane prepolymer. About 30 parts by weight of methyl methacrylate, about 25 parts by weight of 2-hydroxyl ethyl methacrylate and about 0.3 part by weight of an alcohol were added and heat-polymerized to prepare urethane acrylate .

In addition, the lithium silicate (SiO ₂ ) is used as a surface strengthening agent for a structure made of a cement material such as cement, mortar, concrete, calcium silicate.

Lithium silicate (SiO ₂ ) penetrates into the concrete surface and chemically reacts with the free alkaline components of the concrete to reinforce the concrete.

The polymethyl methacrylate may be mixed with urethane acrylate to improve the strength of the structure made of resin.

In addition, the 2-hydroxyl ethyl methacrylate is used in the present invention in addition to the urethane acrylate and the polymethyl methacrylate resin. In order to reinforce the strength of the block, hydroxyethyl methacrylate (hydroxyl ethyl methacrylateA) can be additionally used.

On the other hand, the sodium silicate (Na ₂ SiO ₂ .nH ₂ O) is referred to as a sodium salt of silicic acid.

Depending on the composition (composition), sodium metasilicate NaSiO, its hydrate sodium orthosilicate NaSiO, sodium diacetate NaSiO, but usually refers to sodium metasilicate.

A hydrate is made by solidifying a mixture of quartz and sodium carbonate by heating and melting at 1,000 ° C.

Sodium metasilicate dissolves well in water and the aqueous solution becomes alkaline by hydrolysis.

Therefore, in a dilute aqueous solution, it can be quantified using an acid.

Hereinafter, the production of the main resin composition of the loess pouch composition according to the present invention having the above-described structure will be described.

The method for preparing the main resin composition of the loess pavement composition according to the present invention comprises: 25 to 30% by weight of methyl methacrylate; 25 to 30% by weight of polypropylene glycol acrylate; 5 to 10% by weight of butyl acrylate; 4 to 5% by weight of polyoxypropylene glycerol triether; 0.1 to 1% by weight of lithium silicate; 1 to 2% by weight of a surfactant; 1 to 2% by weight of a polycarboxylic acid-based fluidizing agent; And 30 to 38% by weight of water.

The main resin composition of the loess pavement composition according to the present invention having the above-described constitution and production can obtain the test results as shown in Figs. 1 to 10.
