Description

Eco-friendly soil hardening composition and construction method

The present invention relates to an environment-friendly soil hardening composition and its construction method, more specifically, can be paved road without cement, sprayed directly onto the soil or used in the form of mixing with the soil, the adhesion, strength and crosslinking with the soil particles It relates to an environmentally friendly soil curing composition having excellent properties and a construction method thereof.

In addition, the present invention does not generate secondary environmental pollution due to the original recovery after cement or asphalt pavement eco-friendly, do not generate toxic to soil and water quality by paving the road by spraying or blending in the soil, preservatives to prevent corruption The present invention relates to an environment-friendly soil hardening composition and a construction method thereof, which can suppress side effects of polluting soil by releasing environmental hormones.

In the case of general building materials, a lot of cement is mixed with soil, and a soil hardener is used to increase the strength of cement mixed soil and to speed up the curing speed.

In the case of the pavement using soil hardeners, the ground collapses, and the soil surface is damaged due to the repeated process of freezing and thawing under the condition of freezing and thawing of the soil and the fixed material of the construction as in winter in Korea. It causes the problem of cracking and the surface is cracked when thawing through the winter season, which causes additional disposal cost or the waste of industrial waste when the surface is too cracked to release the pavement.

Soil hardener is limited in use due to sticking sand, warm climate and rainfall and humidity, and it is restricted in construction in four distinct regions like four seasons and emulsion freezes in sub-zero weather. As the particles of the resin are destroyed, the function of the fixing agent is decreased, and the inconvenience of maintaining and maintaining the temperature of the image during storage and the loss of economical cost are exposed.

Therefore, in recent years, attempts to use water-soluble emulsions such as methyl methacrylate, polyvinyl alcohol, ethylene-vinylacetate copolymers, and the like have been increasing.

However, in the case of using such polyvinyl alcohol, due to the limitation of the vinyl material, surface strength, flexibility, and water resistance are not good, so that sufficient water resistance cannot be imparted to the soil surface, and when the moisture content is high, polyvinyl alcohol swells.

In addition, the ethylene-vinylacetate copolymer is emulsified using a protective colloid, and thus can be applied and controlled in terms of workability due to the change in viscosity and fluidity. It is pointed out that problems such as surface peeling due to poor surface strength, flexibility, and water resistance are caused, and soiling is caused.

For this purpose, road pavement methods using acrylic emulsions or vinyl emulsions have been introduced, but the use of a large amount of surfactants prevents freezing during the winter season and the use of preservatives to prevent the decay of the composition. It causes side effects that pollute.

In addition, the soil curing agent of the acrylic emulsion or vinyl emulsion, in the case of cement added to the solidifying agent to add a coloring agent including iron oxide containing heavy metal in order to give a yellow earth color, the harmful components of the human body is mixed, causing problems that are not environmentally friendly.

The ethyl vinyl acetate is an ethylene polymer that is a flexible material and is used to sinter porous materials such as rubber materials.

The isobutyl acrylate, 2-ethylhexyl acrylate, octyl acrylate, octyl acrylate will be used to improve adhesion with soil particles.

The mixture is composed of magnesium chloride, potassium chloride, sodium chloride, calcium chloride, sodium sulfate and sodium silicate. Looking at the characteristics of each component, the magnesium chloride is mixed with other compounds to promote the curing rate of the soil, and to provide adiabatic effect It is a colorless crystalline powder that has a strong hygroscopicity and is soluble in water and alcohol. It is also used as a raw material for the manufacture of metal magnesium, and magnesium oxide is mixed to form magnesium oxide.

The potassium chloride is mixed with other compounds to close the pores to increase the strength, and is a compound consisting of ionic bonds of potassium and chlorine, well dissolved in water and flows well. It is industrially used as a raw material for the preparation of potassium salts, and as a buffer solution and an electrode solution in the laboratory. The single crystal of potassium chloride is used for the preparation of windows of prisms and cells used for infrared absorption measurement, and other heat treatment agents, photographic reagents, Used as medicine.

In addition, sodium chloride plays a role of increasing the strength by closing the pores of the soil like potassium chloride, and is important as a raw material for the production of other sodium salts such as chlorine, hydrochloric acid, sodium, and sodium hydroxide, and is used as a storage and raw material of various foods.
