Concrete blocks are paved facing each other by continuously arranging sidewalks, driveways, housing complexes, plazas, parks, parking lots, etc., in consideration of urban aesthetics and convenience of walking or driving. These concrete blocks are used for various purposes such as various shapes such as cubes, cuboids, and polyhedrons, braille blocks, induction blocks, sidewalk blocks, driveway blocks, parking blocks, square blocks, and park blocks. In particular, in the case of bochado blocks, cement, sand, gravel, and water are appropriately mixed in a certain ratio, and then the mixture is molded and cured using a vibration press molding machine.

These concrete blocks are used only as paving blocks, but recently, problems caused by fine dust consisting of fine particles floating in the air have become increasingly serious, and nitrogen oxides (NOx) are known as substances that cause fine dust. In particular, since a significant amount is emitted in the process of driving a car on the road, pollutants such as fine dust and nitrogen oxides (NOx) are repeatedly accumulated and contaminated in concrete blocks. In recent years, a technology for removing air pollutants, especially nitrogen oxides (NOx) contained in automobile exhaust gas, has been developed using a block containing a photocatalyst, and a member using a photocatalyst material is embedded in a concrete block. Methods for producing built-in blocks to be inserted or integral blocks in which photocatalyst particles are added to cement mortar during molding are known.

In this concrete block, since the photocatalyst is buried inside the concrete block, unnecessary waste of the photocatalyst is caused, which greatly increases the manufacturing cost, and the photocatalyst particles added to the cement mortar before molding are not evenly distributed in the cement mortar. Therefore, there was a problem such that the cleaning effect by photolysis after construction did not appear uniformly on the surface of the concrete block.

Korean Patent Registration No. 10-2149282 (registered on August 24, 2020) discloses a concrete block for roads using photocatalyst-impregnated shells as an aggregate to reduce fine dust and surface pollution and to purify the air.

After immersing a shell having a particle size in the range of 1 to 8 mm in a silver photocatalyst emulsion, pressurized to impregnate the multilayer structure of the shell with the photocatalyst emulsion, coat the surface with the photocatalyst emulsion, and dry it. It is characterized in that the coated photocatalyst is exposed in a sustained release, so that fine dust and surface pollution reduction and air purification functions by the photocatalyst are continued. According to the disclosed technology, a base layer portion molded from a base layer mortar composition including cement, coarse aggregate, fine aggregate, and water; Cement, fine aggregate, and photocatalyst are impregnated into the multi-layered structure of waste shells, and waste shells containing oyster shells or clam shells coated on the surface and surface layer molded with a surface mortar composition composed of an appropriate amount of water are composed of oyster shells or shells The photocatalyst impregnated into the multi-layered structure of the waste shell containing and coated on the surface is exposed in a sustained release, allowing the photocatalyst to continue reducing fine dust and surface pollution and purifying the atmosphere.

Korean Patent Registration No. 10-0875458 (registered on December 16, 2008) is a technology that can continuously remove nitrogen oxides and organic compounds in the air by using titanium oxide powder recovered from a coagulant injected into wastewater to remove organic compounds. A method for manufacturing a sidewalk block using a photocatalyst recovered from wastewater is disclosed. According to the disclosed technology, a recovery step of recovering sintered titanium oxide powder by sintering the agglomerates generated by the coagulant introduced to remove organic compounds in wastewater; A body molding step of molding a body by mixing aggregate, cement, and water; A surface layer forming step of forming a surface layer on the top of the main body by mixing cement, sand, and water with sintered powder; It is characterized by including a curing step of curing the main body and the surface layer, so that a photocatalyst capable of effectively removing air pollutants such as nitrogen oxides (NOx) by sunlight is used, but from by-products generated in the process of treating wastewater By recovering and using titanium oxide, it is possible to reduce recycling of resources and manufacturing costs.

In the conventional technology as described above, in the case of existing photocatalysts, there is still difficulty in application to functional materials due to low photoactivity, and the photocatalyst-related market is expanding globally to various fields such as interior and exterior materials and environmental purification systems. However, the fact that the existing photocatalyst is expensive in terms of cost acts as a disadvantage in terms of economy. Therefore, when such an expensive and low photocatalyst is used in a block, its reactivity is low and economically inefficient, so it is difficult to achieve a competitive advantage in the related market. It is difficult to expand, the manufacturing process is complicated, mass production is not easy, and it is difficult to apply easily.

A power terminal forming step of connecting a positive terminal to one side of the photocatalyst impregnated in the impregnation step and forming a power terminal by connecting a minus terminal to the other side of the photocatalyst impregnated in the impregnation step; a shielding plate forming step of forming a shielding plate on the upper surface of the photocatalyst impregnated in the impregnation step; and a heating line forming step of forming a heating line formed on the upper surface of the shield plate formed in the shield plate forming step and connected to each of the power terminals formed in the power terminal forming step. A photocatalyst applied block manufactured by the applied block manufacturing method.
