Description

Building Powder Mixture

The present invention relates to a building soil powder mixture, and more particularly to a soil powder mixture for the soil wall or ground for improving the residential environment due to the beneficial components to the human body in the soil.

In general, a variety of buildings that are being constructed in recent years is mainly composed of a concrete structure cured by mixing cement, gravel, sand, water.

Such a building has excellent durability, but since the material itself is an artificial material, there are no factors that are beneficial to the human body. Moreover, concrete has many harmful factors in terms of environment, such as by-products causing environmental pollution, and the smell of cement in buildings until it condenses.

In general, concrete structures cannot control the humidity and air purification in the room without additional control, and the insulation effect is remarkably lower than that of the soil, which increases heating and cooling costs. In particular, concrete construction may be the main reason for poor construction, but in the winter season, due to the temperature difference between the outside and the room, moisture is generated in the wallpaper, causing mold, which may cause odor.

In contrast, loess soil contains various minerals and nutrients that are beneficial to plants and animals. These minerals and nutrients are very useful not only for animals and plants but also for the human body.

The application of soil can be seen in traditional medical fields. In the herbal medicine books, Herb Herb and Mokje, the soil contains detoxification, various purifying ability, for example, poisoning. , Detoxification, thirst, earth and sand frenzy has been described as excellent efficacy.

Even if this field is not medical field, the research on soil is more actively conducted. According to the results of the research, first, ocher soil contains a large amount of ceramic components that generate far-infrared rays effective to the human body. In this case, it has finer particles than ordinary soil, so it has high oxygen content and ability to capture foreign substances. Third, there is a large amount of dissolved oxygen, which purifies the air, deodorizing ability to remove odor, and degreasing ability to remove oil. Turned out to be).

In addition, Jijangsu, which has filtered ocher soil, may be used to balance the body's biological rhythm or to heal various diseases.

Therefore, in the past, various buildings or daily necessities made of ashes have been widely applied in real life, and earthen walls, hanok, ondol rooms, urns, etc. are good examples. In particular, the jars can be stored for a long time without deterioration even if they contain various kinds of miso, red pepper paste, soy sauce, etc., and in the case of the traditional hanok, the walls and floors are built of soil so that no cold air or moisture is generated from the walls. .

However, it has been pointed out that the earth walls, earth walls and the like have weak durability such as being weak to moisture and easily broken. In particular, in the past, due to the undeveloped construction materials, mud walls or mud-blocks were made by using mud, which was mainly used for exterior walls and walls of buildings. The reason why such soil is mainly used for exterior walls is that when the soil is dried, dirt or debris falls from the soil wall, and is easily broken even in minor impacts.

The present invention can be constructed more beautifully by developing a lot of natural ocher soil as a building material, and was devised to provide a living environment that is beneficial to the human body.

It is an object of the present invention to finely powder ocher soil containing components beneficial to the human body to provide a building soil powder mixture that can be used as a construction material or surface finishing material on the wall or floor when dried and mixed with water anytime and anywhere It is.

Another object of the present invention is to be used as a surface finishing material of various buildings to purify the air in the room, to adjust the humidity to an appropriate level naturally, and early to various diseases that may occur in the human body It is intended to provide a building soil mixture that can be prevented.

Still another object of the present invention is to make a soil wall, a soil floor using natural materials to prevent the environmental pollution by the by-products, at the same time, the recyclable building soil powder mixture to reduce the construction cost To provide.

In order to achieve the above object, the present invention is 50 to 70% by weight of the powdered ocher soil dried by filtering to about 10 to 100 mesh, 3 to 15% by weight of the water-absorbing material of the dried form having a particle size of the predetermined size, and powdery It has the characteristics mix | blended in the ratio of 1-5 weight% of caking agents, 1-5 weight% of powdery surface hardening agents, and 1-5 weight% of fragrance | flavor.

Hereinafter, embodiments of the present invention will be described in more detail.

First, the water absorbing material defined in the present specification is meant to encompass rice straw, dried steamed rice, chaff, sawdust, various herbs, straw, etc., to give toughness to the dried earth wall, the moisture contained in the wood base and the air In this case, it means a material having the ability to absorb moisture and to release the absorbed moisture into the atmosphere when the moisture contained in the atmosphere is low.

A caking agent means that viscosity occurs when combined with water, and more specifically, powdered starch, etc., which are combined with water to form a scavenger.

The surface hardening agent is a substance for preventing the surface of the dried soil wall from being broken or falling off of the soil. More specifically, the surface hardening agent is added for the purpose of hardening the soil surface, for example, salt.

The fragrance is added to the soil so that a unique fragrance is emitted from the soil, and the fragrance includes herbal medicines such as pine needle powder, Angelica, Cheongung, peppermint, licorice, dermis or juniper.

As the above-mentioned water absorbing material, it is preferable to use rice straw having excellent water absorbing ability to absorb and release moisture in the air compared to other materials of the same group.

When the rice straw is used as a water absorbing material, the size is cut to about 1 to 3 cm, and the reason is that it is evenly distributed in the case of being mixed with the powdery loess soil and makes the surface of the soil wall relatively beautiful. This is to strengthen the binding force of the soil and to make the natural humidity control function.

Rice straw has a function of improving the moisture resistance, breathability and impact resistance of the molded earth wall in addition to the above functions.

In other words, the soil wall has a problem of low impact resistance when the air permeability is excellent, and the air permeability decreases when the impact resistance is strong. The relationship yielded the most desirable results.

It is preferable to use starch as caking agent. Starch improves the cohesiveness of soil with viscosity when mixing soil powder mixture with water and constructing soil wall by plastering method. Agglomeration function to prevent falling.

It is preferable to use salt as the surface hardener, and salt functions to harden the surface of the soil wall when the soil powder is mixed with water by the plastering method. This is because the salt crystals dissolve in the soil when kneading the soil powder with water, so that when the constructed soil wall is dried, the crystal grains of the evaporated moisture are generated to combine with the water in the soil. This will harden further.

EXAMPLE

In order to confirm the most preferable mixing ratio of the soil powder mixture according to the present invention, after mixing in the ratio of 55% by weight ocher soil, 20% by weight straw, 10% by weight starch, 10% by weight salt, 5% by weight pine needle powder and It mixed suitably and produced Sample 1 which is 30 cm in length and 2 cm in thickness, respectively.

70% by weight of ocher soil, 15% by weight of straw, 5% by weight of starch, 7% by weight of salt, and 3% by weight of pine needle powder, and then mixed with water as appropriate. Sample 2, which is cm, was made.

In addition, 85% by weight of yellow soil, 7% by weight of straw, 3% by weight of starch, 5% by weight of salt were mixed, and then mixed with water as appropriate. Sample 3 having a width of 30 cm and a thickness of 2 cm, respectively, was prepared. made.

The samples 1, 2, and 3 thus prepared were completely dried at room temperature, and then tested for surface strength, impact resistance, breathability, and water absorption for each sample as follows.

In order to test the surface strength of samples 1, 2, and 3 of the same size, each sample was placed on a flat bottom, and a pushpin having a load of 30 kg was dropped freely from vertically above 30 cm. The depth of the sample was measured.

As a result, the embedding depths of the pushpins for the samples 1, 2 and 3 were approximately 4.3 mm, 3.7 mm and 3.5 mm, respectively.

In order to test the impact resistance against Sample 1, Sample 2 and Sample 3 of the same size, each sample is placed on a flat bottom, and a weight with a load of 80 kg is dropped freely at a vertical position of 30 cm above each sample. The degree of breakage of the sample was measured.

As a result, Sample 1 was completely broken, Sample 2 was sometimes broken or not broken, and Sample 3 was hardly broken.

In order to test the air permeability of Sample 1, Sample 2 and Sample 3 of the same size, each sample was pressurized for 1 minute with a piston having a load of 50 kg, with each sample fixed to one end of a cylindrical cylinder 30 cm long and wide. The moving distance of the piston relative to the sample was measured.

As a result, the piston moved about 3 cm for Sample 1, the piston moved about 1.2 cm for Sample 2, and the piston moved about 0.4 cm for Sample 3.

In order to test the absorbency of Sample 1, Sample 2 and Sample 3 of the same size, each sample was placed in three vessels containing 1 liter of water and allowed to use at a temperature of 50 ° C. for 30 minutes. The amount of water remaining in the was measured.

As a result, 0.85 liters of water remained in the container containing Sample 1, 0.88 liters of water remained in the container containing Sample 2, and 0.95 liters of water remained in the container containing Sample 3.

The results of these experiments are shown in the table below.

As can be seen from the above experimental results, it can be seen that as the amount of water absorbent increases, the surface strength and impact resistance decrease, but the air permeability and absorption improve. However, air permeability and water absorption are slightly reduced.

As the amount of the surface hardener increased, the surface strength and the impact resistance were improved, but the air permeability and the water absorption were slightly lowered. The fragrance was found to have little effect on the physical properties.

According to the above experimental results, the soil powder mixture according to the present invention is 70% by weight of powdery loess soil, 15% by weight of water absorbent, 5% by weight of fragrance, 5% by weight of binder, 5% by weight of surface hardener. It turned out that being the most desirable effect would be.

Of course, the above-described experimental value is a result of selecting any one of the covering materials, but the other materials belonging to the group generally show similar results.

According to the test results, it was confirmed that rice straw has the most active function among the materials of the moisture absorbent. As the moisture absorbent other than rice straw, dried sawdust and dried chaff are used.

According to the present invention, since it does not emit harmful substances by using natural materials, almost no environmental pollution is generated, and when the soil wall is made of the dust powder by mixing spices or herbal medicines with the soil powder, it is always soft The fragrance emanates, which has the effect of creating a fresher living environment.

In particular, when there is a disease in the bronchial system, when the herbal medicine prescribed by a specialist is added as a flavor and mixed in the earth powder, the perfume emitted into the atmosphere may indirectly affect the human body through the respiratory tract may generate a therapeutic effect.

As described above, the soil powder mixture according to the present invention can not only naturally control the humidity of the room through the beneficial components and moisture absorbents that the soil has when used as an interior finishing material (wall, flooring, and ceiling material) of the building. It can be expected to purify indoor air.

In addition, when the construction using the soil mixture mixture for construction according to the present invention, the cold air is not generated in the wall, it is possible to fundamentally prevent the mold from blooming due to moisture.
