Description

Natural soil block and the manufacturing process

The present invention relates to a natural earth block for civil engineering and construction using earth and sand collected from nature, in particular, the use of environmentally friendly materials to comply with the natural environment, harmful substances do not occur, recyclable civil revetment block or grass block, And it relates to a natural soil block including a building brick and a method of manufacturing the same.

In the case of materials such as concrete revetment blocks and cement bricks that are used for civil engineering and construction, a large amount of cement is basically used to generate harmful substances in the natural environment and cause cancer or atopy, such as serious harm to people and nature. Is interfering. In the civil engineering materials, various revetment blocks are used in the river maintenance business. In the 1970s, industrialization and urbanization began to focus on uniform and artificial river maintenance considering only simple dimensioning and economic feasibility. As a result, the vast majority of tributary streams managed by 4,000 km of national and local rivers and municipalities are covered with cement concrete.

The use of such cement concrete has caused problems such as disrupting the river ecosystem, deteriorating soil corrosion and water purification ability, lack of benthic biodiversity. In addition, cement, the main material of concrete blocks, requires a lot of natural resources and energy to be consumed in manufacturing. Despite this situation, cement-based materials are used continuously in most natural rivers.

Efforts to curb the use of cement materials and development of eco-friendly products can create a river where the eco-environment is alive and reduce the burden on environmental pollution.

Building materials have also become more environmentally friendly, with the improvement of living standards and the emphasis on a pleasant living environment. As a representative example of building materials using ocher, ocher bricks are manufactured by various methods and used in buildings. However, the ocher brick is produced by heating and baking at high temperature of 1,100 ℃ or higher to increase durability. In addition, the ocher brick consumes a lot of energy and generates harmful substances to the environment. It is lost and at the same time ceramicized. The ceramic clay loess bricks cannot be recycled and thus remain a waste. In addition, there is an ocher brick which is reinforced with durability by adding cement to the ocher, which is a main raw material, instead of firing by other methods of producing ocher brick. However, the manufactured ocher brick has a disadvantage in that harmful substances are generated from the cement component contained in the ocher main component.

Therefore, the use of cement and the depletion of natural resources are prevented, and there is no need for the firing process that is a source of energy consumption and environmental pollution, and the development of new technology that can be easily used in various places with the same or better product quality as cement concrete. It is required.

An object of the present invention relates to a natural soil block using soil collected from nature, in particular, there is no calcining process that causes enormous energy consumption and environmental pollution, and conforms to the natural environment by using environmentally friendly materials and harmful substances are generated. The present invention provides a natural earthen block including a civil engineering revetment block, a grass block, and a building brick that can be recycled.

The present invention for achieving the above object, in the natural soil block, 60 to 90% natural soil, 5 to 12% moisture, 100 to 160 mesh particle size, zeolite 1 to 12%, 100 to 200 mesh High pressure molding was performed by adding water, mixing and stirring to a material mixture of 10 to 30% of Masato having a particle size of 8 to 20% of inorganic powder and ₂ to 8% of solidifying agent including SiO ₂ , CaO and Al ₂ O ₃ components. Characterized in that it is configured to be a natural earth block for civil engineering and construction.

Natural soil block of the present invention has the following effects.

First, the natural soil block of the present invention has the advantage of realizing an eco-friendly material having the same or more durability than the general concrete block without the addition of heating firing and cement, and produced by stirring and pressure molding by mixing the eco-friendly material Reducing pollutants and returning to nature through the weathering process can reduce waste disposal costs and recycle.

Secondly, the natural earth block of the present invention is free of heavy metals to create an optimal ecological environment to favor aquatic organisms and vegetation of the herbaceous earth, when using soil mixed with ocher emits far-infrared rays beneficial to the human body and generates anions, With antibacterial properties, it can promote eco-friendly functions.

Third, the natural soil block according to the present invention can be used as the main material of all soil, such as sandy soil, clay clay, waste soil discarded in the mine, and produced by high-pressure molding without firing process, it is possible to reduce the pollution source such as CO ₂ . . In addition, it exhibits the same or superior strength compared to the existing cement block, the flexural strength, the flexural toughness is more excellent.

Fourth, the natural soil block of the present invention is relatively reduced in the freezing and thawing phenomenon in winter, the durability of the block is longer, and unlike cement concrete in the summer, the heat absorption or heat conductivity is relatively low, so that radiant heat and ultraviolet rays are reduced, thereby reducing the heat island in the city. Preventive and pleasant ecological environment is provided.
