"Function" The method for forming the surface finishing layer of porous concrete material of the present invention described above involves placing the porous concrete material directly on "cement paste mixed with synthetic resin emulsion" that has been poured into a mold in advance. The main part of this process is to solidify the cement paste while applying pressure to form a strong binding waterproof layer at the joint between the cement paste and the porous concrete material, and to use the cement paste as a surface finishing layer. Between the small pores and particles of concrete material,
Since the fluid cement paste is press-fitted and solidified as one, the joint area between the porous concrete material and the cement paste has a so-called "well-known anchoring effect" (also known as fastener), where countless small irregularities intertwine and solidify. At the same time, the synthetic resin emulsion mixed in the cement paste acts as an adhesive, creating a mechanically strengthened and strongly bonded waterproof layer. In other words, the combined waterproof layer at the joint site has better mechanical strength than the porous concrete of the main body, and has a dense structure due to its anchoring effect, so it functions as a waterproof layer.
Even if there is water ingress due to cracks in the surface finish layer, etc.
Waterproofing is provided to effectively prevent water from reaching the porous concrete. Therefore, peeling between the surface finishing layer and the porous concrete of the main body cannot occur under normal usage conditions.Porous concrete with a high quality surface finishing layer has excellent peeling resistance, impact resistance, and high waterproofing properties. Materials can be molded.

Furthermore, the above-mentioned molding method of the present invention directly molds a surface finishing layer made of cement paste poured into a mold onto the porous concrete material of the main body, so the molding method is simple and efficient. By selecting the shape of the mold and using colorants and pigments in the cement paste, it is possible to freely form various patterns on the surface finish layer.
