Description

A inorganic material for ac climation use of male chemosterilant mineral}

The present invention relates to an inorganic material for environmental restoration using hydrochemical minerals for greening and soil stabilization, and more specifically, a predetermined thickness on a target slope on which a wire mesh is installed by mixing with greening soil, seeds, fertilizer, admixture, water, and the like. The present invention relates to inorganic materials for environmental restoration using hydrochemical minerals used for greening.

Conventionally, a vegetation spraying method of vegetation-based materials using inorganic materials has been implemented in order to green the slopes generated by various construction works according to the development of national land development and industrialization.

However, the conventional vegetation-based inorganic material used in the above-described method has the following problems.

That is, (1) The inorganic materials for environmental restoration used in the conventional construction methods are generally dry curing reaction type, and the drying curing stabilization time is long, so there is a variation depending on the thickness of the construction, but it takes about 2 to 3 days after the construction. If there was rainfall within the curing period after construction, there was concern that the newly established vegetation base would be lost.

(2) The conventional inorganic material for environmental restoration should use a separate granulating agent to form granules, but the variation is large depending on the mixing ratio, resulting in uneven granules, and the surface hardness paper (measured by acid stiffness meter) is 30. There was a long period of time for greening because seeds were germinated due to softening due to water absorption of the construction surface when there was sufficient rainfall.

(3) The conventional inorganic material for environmental restoration is stabilized when various construction materials are used. Therefore, it is formed when using a thin layer (THK 1-3 cm) vegetation spraying method with high cost and uncertainty. Due to the unstable coating, defects, cracks on the surface, and many fines were generated due to rainwater, resulting in unsatisfactory results.

Therefore, the present invention has been made to solve the conventional problems as described above, since the inorganic material administered within 2 to 3 hours after construction is hydrated with water and water-resistant granulation proceeds, there is no fear of loss in normal rainfall, The stable water-resistant single grain is porous and has excellent water retention and soil breathability, so even if a thick or thin film is formed at a time, the germination rate of plant seeds is formed high on the entire stable film surface, and excellent growth conditions can be achieved and early greening can be achieved. It is to provide inorganic materials for environmental restoration using hydrochemical minerals, which have not occurred any anti-corrosion phenomenon.

The present invention for achieving the above object is made by mixing 50% to 80% of pulley ash, 5% to 20% anhydrous gypsum, 5% to 20% cement, 1% to 10% aluminum sulfate, 1% to 5% potassium carbonate. There is this.

Hereinafter, the present invention will be described in detail.

The inorganic material for environmental restoration of the present invention is composed of Sio₂50-60%, Al₂O₃25-35%, and other components of about 15%, and is a fine powder having a particle diameter of 0.3 to 1 mm and dispersed in water in a colloidal form. It reacts and hardens to mineral hydration reactants such as edringeite and calcium silicate hydrate, and it controls the pojoran activity, which greatly influences the fluidity, neutralizes the acidic soil with alkaline substance, and helps to improve soil disadvantage. 50-80% Flyash with;

The main constituents are Sio₂22%, Al₂O₃ + FeO₃9%, CaO + MgO 65%, and other 4%. 5-20% of conventional cement which is produced and has strength function;

5-20% of anhydrous gypsum (CaSO4), which reacts with water to form monoedgringite and helps maintain strength with cement;

1-10% of aluminum sulfate (Al2O₃), in which a polyhedron ion of aluminum is formed as a polymer itself between the components dissolved in water and dissolved into water as an electrolyte, and dispersed in a colloidal phase by water;

Potassium carbonate (1-5%), which is a silicate fertilizer without acidifying the soil by validating the poorly soluble silicic acid (SiO₂) contained in the fly ash, is mixed to prepare an inorganic material.

The inorganic material of the present invention prepared as described above is the same as a friendly member of silicic acid (SiO₂) and aluminum sulfate (Al₂O₃), which are the main constituents of the silty soil, which is the weathered granite, which occupies the whole area of Korea. By mixing with the hydration reaction, water-resistant granulation, and the proper strength is maintained.

In addition, the inorganic material of the present invention forms a net phase crystal that binds the silt soil particles of a vegetation-based material while hydrating with water to form porous pores, thereby covering the surface of the particles rather than the single grains where each particle is adhesively cured. Formation is a complex porous monolith in which filling is formed in the voids between a plurality of particles of a hydrated compound, thereby maintaining its hardness and strength.

Therefore, the finished granule is a porous material that maintains strength and constant hardness (within 24 hardness value) and absorbs moisture in the soil, which is excellent in breathability and water retention, and is a form of fertilizer containing long-lasting fertilizer. The reactive component itself also has the toxin of being calibrated.

Example 1

(1) Mixing 75 kg of fly ash (for Seocheon thermal power), 15 kg of cement (manufactured by Hyundai Cement Co., Ltd.), 5 kg of anhydrous gypsum, 3 kg of aluminum sulfate, and 2 kg of potassium carbonate. After manufacturing and packing 300 kg of material 100 kg

(2) Masato 3㎥ (1,700㎏ / ㎥ * 3 = 5,100㎏), 1,000kg fly ash, 100kg anhydrous gypsum, 200kg peat (PEAT), 100kg organic fertilizer (20kg packing 5 bags), compound fertilizer 20 Masato vegetation base material mixed with kg was prepared and packaged three times in the same manner.

Using the above materials, it was applied to the surface of 50m2 of the rigging arm slope of the same site 1: 0.7, and 200m2 of the total surface of the sloped Masato slope with a slope of 1: 1.

The construction was done by using a wet attacher (tank capacity 4,000 l) and mixing and mixing the raw and wood-based seeds in (1) (2) material to 1,500 liters of water in the tank. It was adhered by spraying and sticking, and the thickness was once (one tank capacity) 120cm in 2cm, 3cm in 2nd, 50㎡, 3cm in 5cm, but all adhered well. After 3 hours, it was confirmed that the internal hardening was sufficiently progressed, and the seed spraying machine was mistaken on the whole surface the next morning, but there was no loss of the material sprayed at all. Five days after surface hardening, the hardness value was 24mm, and after 3 weeks of construction, seed germination was found in the whole surface.

Example 2

In the actual construction example (1), 12 kg of cement and 8 kg of anhydrous gypsum were prepared by adjusting the ratio, and the plant seeds were mixed in the Masato vegetation base material. During the 240㎡, rainfall occurred over 2 hours after the end of the construction, but there was no scour or dripping after the rainfall.The hardness value was 22㎜ after 3 days and the seed germination started after 10 days. It was confirmed that it germinated around 20 days.

Example 3

As a result of mixing and mixing the inorganic material of Example 1 to the soil with a high moisture content, as shown in the following "Table", while the water was rapidly absorbed by the hydration reaction, the granulation proceeded to solidify and stabilize.

Example 4

The slope of the slope of the weathered rock is 5m, 8m, 7m in length, and 2.5m in depth. The inorganic material of Example 1 was sufficiently mixed, and a small amount of water was added to the pressure-diffusing mixture using an Ariva machine to spray it at high pressure to complete filling soil (120㎥), but no dropout or loss occurred. The sediment sprayed on was adhered and filled in a stable state with the surrounding ground stably by hydration reaction, water-resistant monolithic formation and hardening reaction, and the rainy season started after 3 days, but no drooping or loss phenomenon appeared. There was no sign of frostbite and no change of surface at all. It said that after the spring has been confirmed by the kind of growth sprouting seeds flowing around the construction side. As a result of this, the conventional method has been performing the shotcrete method by hitting the wire mesh on the circumferential surface cavitation by dropout, but the joint bend is intact. It can be seen in a groundbreaking way as it can achieve stable recovery and plant growth without any additional damage to the surroundings.

As can be seen in the previous embodiment, the inorganic material of the present invention is composed of a mixture of hydration-reactive materials so that hydration reactants such as edrinite and monoedrinite are rapidly formed by rapid hydration of each component. This results in the formation of water-resistant granules in the state of enveloping soil particles, and the formed granules are complex porous granules made of Net phase crystals to maintain their hardness and strength. The long lasting effect and the hydration reaction component itself are calibrated to achieve eco-friendliness and economic feasibility. The soil and part of the slope of the gneiss-like weathered Masato soil construction damage, which occupies the land of our country Improvement of soil acidified by greening using large amount of fly ash It can be performed longitude friendly perfect record ball without heterogeneity.
