摘要
The present invention is a top surface of a cement concrete block formed by mixing coarse aggregate finely crushed bottom ash from coal-fired power plant with cement, and the loess layer formed by mixing an appropriate amount of fine particles of loess powder, coagulant, and clay. Lay it up to a thickness of 3, and form at least 3-4 permeable holes that can be filled with coarse sand to the same depth as the thickness of the yellow soil layer. As a permeable block with an ocher layer bonded to the upper surface to be widely applied not only for the paving of roads and roads, but also for paving such as plazas and parking lots, the hard image felt from cement concrete by the ocher layer laminated to the upper surface of the cement concrete block body. It can remove the feelings of rejection and is also friendly to the surrounding natural environment. The purpose of the present invention is to provide a high permeability block having a high strength and durability in which the permeation action is quickly made to the lower block body through the coarse sand filled with the perforated hole formed by the ocher layer so that the perforation is formed.;Block body, top surface, ocher layer, perforator, coarse sand
