Description

Korean Hypocaust and Mortar With Increased Strength Made From Korean Loess, and The Preparation Method Thereof}

Recently, the function of ocher is gradually revealed, and there are increasing attempts to use ocher as various building materials. Loess has been used as a building material since ancient times, and especially when living in a loess-built house, it has been known to be very beneficial to health due to the far infrared rays emitted from the loess. However, in modern times, due to the high and large scale buildings, ocher has been discarded as a building material, and concrete is used instead of the ocher, which is enough to support high-rise and large buildings in its strength. Because it did not show the strength. On the other hand, concrete buildings and houses are not only poorly breathable, they are also good for molds and pests, and nano gases emitted from concrete are accumulating in the environment, which adversely affects the human body. One of them is an attempt to use loess as a building material. However, as mentioned above, in order to use ocher as a building material, bricks made of ocher must have a certain strength and durability, and there are no known ocher bricks that satisfy the strength required in industrial sites.

For example, Korean Patent Application No. 10-2001-0038634 (published on September 3, 2001) discloses ocher bricks, ocher tiles, and ocher mortars, but here, the ocher clay contains various herbal medicines. The ocher brick and the ocher mortar are manufactured using the above, and no means of increasing the strength of the ocher brick is disclosed.

The present invention relates to an ocher brick having an increased strength, an ocher mortar and a method for producing the same, and have problems of conventional ocher bricks, that is, they do not have satisfactory strength and lack of robustness against east sea or moisture. It is a technical problem to solve the problem, which is achieved by using a solidifying agent which is a characteristic component of the present invention, and also by mixing a loess, mica and hardening agent in a specific ratio. In particular, the ocher brick of the present invention has an increased strength, unlike the conventional ocher brick, it is possible to apply it to large, high-rise buildings, the effect of the loess as a building material, that is, the humidity control function, insulation insulation It can build houses and buildings with functions, antibacterial insect repellent effect, air purifying function and water vein blocking function.

The composition of the ocher brick of the present invention is composed of 25-40% of ocher, 10-25% of mica, 15-25% of hardener, optionally 10-40% of martha (soil), or sand 10-40%. The solidifying agent consists of 50-60% of the three crude steel portland cement, 30-50% of blast furnace slag, 5-15% of natural gypsum and 0.02-0.05% of AE reducing agent.

In addition, the constitution of the loess mortar of the present invention is composed of 25-40% ocher, 20% solidifying agent, 10-40% martha (dirt), or sand 10-40%, the solidifying agent is three kinds of crude steel portland cement 50-60%, blast furnace slag 30-50%, natural gypsum 5-15% and AE water reducing agent 0.02-0.05%.

And a step of curing the molded brick (F).

In addition, the method for producing ocher mortar of the present invention is the same as the method for producing ocher brick, but there is a slight difference in the amount of water added in the step D, and the molding, solidifying step and curing step The difference is that this is omitted. Hereinafter, individual components used in the present invention will be described.

ocher

Ocher is mainly made of fine sand and has a large amount of calcium carbonate. This calcium carbonate has a viscosity that is not easily broken, and when water is added, it turns into clay. In addition, ocher contains quartz, feldspar, mica, calcite, and the like, and these materials are oxidized with iron to show colors of yellow, purple, red, gray, and pale green. Since ancient times, ocher has been used as a building material in itself, and in particular, it promotes health by activating the physiology of the human body by far-infrared rays emitted from ocher, and in addition to the humidity control, antibacterial and Insect repellent, air purifying, deodorizing, and warming effect make ocher the best building material. However, until now, although the advantages of such loess are well recognized, when the brick, mortar, and spheres are made of loess, they do not exhibit sufficient strength, so the construction using the loess brick has not been widely practiced. It should be noted that the present invention solves this problem. The ocher used in the present invention is fine and clean, and located below 80-100 cm from the surface, which is collected and dried, and then used for crushing. It is important to note that ocher is a sediment composed mainly of silt-sized particles with a diameter of 0.002-0.005mm, mainly mixed with sand and clay, and has a very high porosity, so it is very weak to moisture or the East Sea, and hardens. The technology is very difficult. However, the ocher brick according to the present invention can solidify while maintaining the advantages of the mica and ocher when mixed with the mica that can withstand the East Sea by removing the moisture of the ocher and making the porosity small and the solidifying agent peculiar to the present invention. Note that there is.

mica

Mica consists of germanium and is known to have the following benefits:

▣ oxygen supply

In order to continuously metabolize human cells, nutrients and oxygen are absolutely needed, and oxygen deficiency causes diseases such as chronic carbon monoxide poisoning, anemia, vascular disorders, heart disorders, hypotension, cell aging, and mental disorders.

In recent years, medical experiments have shown that germanium acts as an oxygen catalyst to help the efficient use of oxygen. In other words, when organic germanium is supplied to the human body, extra oxygen provides vitality to the blood, thereby freeing the body from chronic oxygen deficiency.

▣ semiconductor action (current flow regulation action in the body cells): anion effect

The greatest feature of germanium is the semiconductor, which is an electrical property, which has the intermediate property between metal and nonmetal, and is called a miracle element because this property of germanium is the principle that heals all kinds of diseases of the human body.

In other words, germanium has four electrons in its atomic structure, and ions are easily coupled at human body temperature to actively move between electron currents. If a foreign substance is created in the body, the outer electrons of the four electrons become negative and pop out, and the other three are positively charged to harmonize with the body. This role of germanium is the principle that heals diseases of the body, and the acupuncture, moxibustion, and acupressure of the meridians and acupuncture points in the oriental medicine is the same principle of treating diseases by smoothing the semiconductor flow of cells.

▣ immune system

The human body has two main immune systems. First, it is caused by white blood cells, and it is a system that eats pathogens by phagocytosis, and second, it is caused by antibodies. B-lymphocytes are formed by T-lymphocytes. It combines with pathogens and kills the germs.

Therefore, having cancer means that the number of T-lymphocytes is reduced, and germanium proliferates T-lymphocytes to protect the body from cancer cells, toxic substances, and viruses.

In addition, Dr. Sato of the Tokyo Institute of Antibacterial and Bacterial Research at the University of Tokyo, Japan, said that organic germanium is one of B.R.M (bioprotective device activating substances) and has an excellent effect on immunomodulation.

▣ Interferon Generation

Interferon is a sugar-bearing protein and one of the cell-producing B.R.Ms, an anticancer and antiviral substance found by Dr. Isaacs and Linde Mann of England in 1957. Discovered nearly 30 years ago, interferon plays an important role in the immune system and is recognized as a potent anticancer factor.

Germanium enhances the production of gamma interferon without side effects or toxicity in both humans and animals.

▣ Endorphin production promoting action

Organic germanium acts as an oxygen catalyst to help the human body use oxygen effectively. Therefore, supplying germanium to the human body reduces the oxygen demand of the cells, thus promoting the production of endorphine, a natural therapeutic agent for the human body, as oxygen remains in the body. .

Therefore, the fatigue recovery is faster, it can be released from the chronic oxygen deficiency phenomenon, and it gives a clear mind and refreshing feeling.

▣ pain relief

When pain sensation occurs in any part of the human body, an enzyme called enkepurarines is produced in the brain to dissolve and eliminate the pain suppressing substance, enkepurin, so the brain recognizes pain. Therefore, most analgesics are agents that inhibit the Enkepourein enzyme and have a temporary effect. When the analgesic drugs are lowered, the pain recurs again, and side effects and poisoning symptoms are observed. Appears and has no side effects.

▣ Alkaline acid constitution

It inhibits and prevents the aging of amaroids, and neutralizes acidified body fluids and converts them into alkaline substances, which are excreted outside the body by binding to heavy metals, which are pollutants in the human body.

Germanium has the atomic number 32 and the atomic weight of 72.5P, which is classified as two types of inorganic germanium and organic germanium.

Organic germanium is a research drug that is formally approved by Japan's Ministry of Health and Welfare. It is administered to various cancer patients and adult patients in more than 50 medical university affiliated hospitals all over Japan. It is an anti-cancer agent with no side effects and is used in the US, UK, Germany, France, Canada and Russia. It is an element of natural substance obtained international patent and officially recognized by WHO (World Health Organization).

▣ Clinical Trial Result

In 13 separate studies, Ge-132 clearly inhibited tumor proliferation and apparently prolonged survival. In 1985, a Japanese scholar published a hypothesis that the anticancer action of organic germanium appears to be associated with its interferon-inducing action.

Several human cancer studies have been conducted with organic germanium. The results of the first and second human clinical trials show that oral Ge-132 enhances the action of inteferon and NK cells, restores the immune response and ultimately has low toxicity.

Based on the above results, Japanese cancer researchers have doubled the impact on responsiveness and clinical symptoms to determine the effectiveness of Ge-132 in patients with lung cancer who have not undergone chemotherapy or radiation therapy. A blind test was performed. In combination with other treatments, patients treated with Ge-132 prolonged high responsiveness and survival, especially for small cell carcinoma.

These results indicate that the use of Ge-132 during chemotherapy or radiation therapy has obvious benefits to the patient's immune system and general health.

The authors also reported no major side effects associated with the use of Ge-132. Expected effects when Ge-132 is used in combination with other immunochemotherapy include inhibition of tumor growth, reduction of metastasis, and prolongation of survival.

Ge-132 is also said to have recovered the weight loss caused by chemotherapy.

On the other hand, the inclusion of mica in the ocher brick of the present invention is based on the fact that the detoxification power is also enhanced when the highly detoxifying mica is contained in the loess. In case of construction in detached house, apartment, inn, hotel, sauna, hospital, garden, and elderly welfare facilities, especially, in case of jjimjilbang, the emission of far-infrared ray is the highest level. Will be obtained. Mica used in the present invention is ground and mixed with loess. In particular, by using mica, there is also an effect of further increasing the strength of the ocher brick of the present invention.

Solidifying agent

The most characteristic component of the present invention is a solidifying agent. The solidifying agent of the present invention was named by the present inventors as a "green solidifying agent", and such green solidifying agent has a novel composition component and a novel content ratio which are not known in the past. The solidifying agent of the present invention is composed of three kinds of crude steel portland cement 50-60%, blast furnace slag 30-50% and natural gypsum 5-15%, when using the appropriate amount (0.02 to 0.05%) of AE water reducing material in water Use it.

A feature of the green hardener of the present invention is firstly that the triad steel portland cement is used as the hardener. According to Korean Industrial Standard KS L 5201, although there are five kinds of Portland cements from the first general portland cement, the fifth type of sulfate resistant portland cement, the third type crude steel portland cement is used in the present invention. Since the present invention aims to provide an increased ocher brick, the third type of crude steel cement is selected as the type of cement which can increase the strength when mixed with the yellow soil. Attempts to construct bricks by mixing them have not been reported.

A second feature of the green hardener of the present invention is the use of blast furnace slag at 30-50%. Slag is a rock component remaining after iron is separated from iron ore, which is a raw material of iron, in the manufacturing process of steel, and is an environmentally friendly material with unlimited application fields such as cement raw materials and construction civil engineering materials. For example, POSCO produces 26 million tons of steel annually, and a total of 12 million tons of slag is generated in the production process, including 8 million tons of blast furnace slag and 4 million tons of steel slag. Such slag is divided into various kinds, but in the present invention, blast furnace slag is used. Blast furnace slag, when the iron ore, coke, limestone and the like is melted in the blast furnace (blast furnace), the molten slag in which the mineral component is dissolved together with the water of about 1,500 ℃, it is cooled. It looks like a normal rock and its composition is similar to cement.

It should be noted that the use of blast furnace slag in the green solidifying agent of the present invention is intended to slow curing time. That is, in the present invention, since the three kinds of Portland cement are used as the main component of the hardener, the solidification time becomes very short, and thus cracks are easily generated in the curing process of the brick. However, by using 30-50% of the blast furnace slag, the solidification time becomes longer, and thus cracking of the finished ocher brick can be prevented. In addition, in the case of the ocher brick using the solidifying agent of the present invention containing the blast furnace slag, since the generation of nano gas and carbon dioxide harmful to the human body is significantly reduced, it also has the effect of minimizing the effect due to gas emissions.

In particular, in the prior art, the same solidifying agent as the solidifying agent of the present invention did not exist, and it should be noted that the solidifying agent of the present invention is for imparting sufficient strength to the ocher brick. That is, the components of the solidifying agent of the present invention and the content ratio between each component are designed to give sufficient strength to the ocher brick to be produced in producing the ocher brick. A conventional general solidifying agent, for example, a solidifying agent containing a first type ordinary portland cement or the like and a solidifying agent of the present invention shows a very large difference in the strength of the manufactured ocher brick. To prove that it gives increased strength to ocher bricks.

Soil and Sand

In the ocher brick of the present invention, as an optional component, soil (massage) and / or sand may be added. These are all common ones that have been used conventionally, and their content is 10-40% each.

Hereinafter, the manufacturing method of the loess brick and loess mortar of the present invention will be described.

First, the ocher existing below the indicator 90cm is collected, and then it is naturally dried in the shade for one week to one month. The dried ocher crushes it evenly and stores it. Apart from the process of extracting, drying and crushing ocher, the solidifying agent of the present invention is prepared. First, 50-60% of three crude steel portland cement, 30-50% of blast furnace slag and 5-15% of natural gypsum are put into a blender and mixed uniformly, which is used as the solidifying agent of the present invention. Next, uniformly mix 25-40% ocher and 15-25% hardener. At this time, water should be added, and the amount is 7-20%. More specifically, it is preferable to add 7 to 13% of water when producing ocher brick and 10-20% of water when producing ocher mortar. In this case, water should be mixed with 0.02-0.05% of AE water reducing material. In addition, it is also desirable to provide uniformity of the color of the brick produced by adding water and optionally adding a pigment. As mentioned above, the manufacturing process of the ocher mortar is finished, and if it is to be made into brick, it is enough to put it in a molding machine and to dry it in the shade. There are two methods to cure in the water and one to cure in the shade. In terms of intensity, curing in the water has an effect of increasing strength by 30% than curing in the shade. Hereinafter, examples of manufacturing the ocher bricks of the present invention are listed, but the technical idea of the present invention is not limited to the following embodiments, and various modifications are naturally included in the technical idea of the present invention.
