    ROAD BOUNDARY STONE AND MANUFACTURING PROCESS OF THE SAME
    The present invention relates to a road boundary stone and a method for manufacturing the same. Particularly, two types of white granite crushed stone, black granite crushed stone, cement and pigment having a different average particle size on the outer surface of the concrete composition pressed by a press have a certain ratio. It is related with the road boundary stone and a method of manufacturing the same, the coating composition overlaid and then press-molded again with a press and cured to form a hard film showing the texture of natural granite.
    In general, the road boundary stone has been used as the road boundary stone of concrete material, which is properly mixed with cement, sand, gravel and water at a ratio, and then poured the mixture into the boundary stone mold.
    However, road boundary stones manufactured using concrete materials with relatively low cost and high hardness are inevitable in water curing, so they are manufactured by natural drying. However, aging occurs in the process of repeatedly absorbing and evaporating water due to flooding during the rainy season. This occurs and the hardness is lowered, so that even a slight impact is easily broken or cracked.
    In particular, when the outside temperature falls below 0 ° C., such as winter, there is a problem in that the water freezes before the evaporation due to the moisture contained in the concrete and freezes as the volume expands.
    As a result, road boundary stones are often replaced, resulting in pedestrian walking, traffic jams, and costly replacement work, while polishing the surface of demolded concrete curing bodies. Excess waste material and waste water generated in the process has a problem that seriously damage the natural environment.
    Therefore, in order to solve the above-mentioned problems, in the roots, airy sand is mixed with cohesive clay or kaolin, and semi-dry press molding is maintained at a water content of 5 to 8%. In some cases, it may be produced.
    However, in this case, in order to prevent cracking and warping of the product, the moisture content before hot firing should be lowered to 3%, which is the minimum moisture content of the road boundary stone. Thus, it is very difficult to minimize the moisture content to the minimum moisture content of the road boundary stone. There is a problem of being non-productive as it must have a separate drying chamber.
    In addition, the clay or kaolin is mixed with any one of the sand, martha, pottery and wire in a certain ratio, the water content is 4 to 8%, and then semi-dry pressurized by extrusion or press to dry naturally, and to the surface of the product Although the glaze is applied, heated, and dried again, it is difficult to control the mixing ratio even when mixing sand or sand, and in particular, external impact may be applied due to bubble generation due to the particle size difference of the pottery. When the hardness corresponding to the external force is poor.
    On the other hand, although the road boundary stone using pure natural granite is used in addition to the road boundary stone of concrete as described above, it is a serious problem that not only damages the natural environment during quarrying, but also pollutes the environment by waste generated during processing. There is.
    The present invention is to solve all the problems of the prior art, the purpose of which is to prevent cracks and breakage caused by freezing and aging due to the function, and high hardness to be able to represent the texture of natural granite as it is To provide a new road boundary stone with a film of
    Another object of the present invention is to provide a method for producing the road boundary stone.
