Stone-emulating roads plate fabrication process

Abstract

The invention relates to a process for preparing a stone-like road slab, belonging to the cement and cement compositions field. The process is characterized in that the preparation process is as follows: river sands, cements, organic dyes and the cement solution or dye additives are mixed; or colorful sand grains in different colors, which are made in advance, cements and the cement solution are mixed to prepare groups of colorful sand pulps similar to the imitating stone in pattern and color, and the groups of colorful sand pulps are orderly ejected on bottom plates of molds respectively by a throwing jet, and after the multiple ejections or shakes, stone-like patterns are made to form a pattern surface layer, and a concrete reinforcing bottom layer is cast on the pattern surface layer and undergoes tamping, natural maintenance and demoulding; use levels of materials of the groups of colorful sand pulps, the pattern surface layer and the concrete reinforcing bottom layer are prepared according to marked quality requirements of concretes needed. The process of the invention has the advantages of wide material source, low manufacturing cost, simple and convenient process and environmental protection and no radioactivity, and can overcome defects in color and texture of cement colorful ground tiles and show the texture and the effect of natural stones.

Description

technical field

[0001] The invention relates to a manufacturing process of stone-like road slabs, belonging to the field of cement and its composition. Background technique

[0002] Whether it is an urban sidewalk or a country road, the sidewalk slabs are mainly made of cement prefabricated slabs and natural stone. Because the cement prefabricated slabs are economical and affordable, they are widely used. A block of cement prefabricated slabs is mosaiced to form a colorful pattern. A further technology is to use cement to prefabricate stone-like road slabs. The pattern color and texture are very similar to natural stone. However, because some chemical adhesives are used on the surface, so The stability is relatively poor, and it is difficult to be widely used. There is also a prior art with a publication number: CN101100837 invention name "imitation stone surface lime sand floor tile and its manufacturing process", and its main body is also mixed with natural silica sand and...

[0030] Embodiment 3: method of imitating mushroom stone, grinding stone, polishing stone slab

[0031] The river sand is pre-colored, and the imitation stone colored sand is processed. The pre-processed colored sand of various colors and cement and cement solution are mixed and proportioned according to the color of the imitation stone, and the retarder is applied to the bottom of the mold. , use a vibrator to shake and press once, and after demoulding, rinse with water to remove the surface grout. The specific method is:

[0032] (1) Use natural clean quartz stone river sand with a particle size of 1.5-3.5mm, and mix it with cement and river sand with a mortar mixer according to the pigment of similar color to imitate the stone, according to 100 parts of cement and 400-400 parts of coarse river sand. 500 parts, mixed with the patterned surface layer modified water solution, the amount of the patterned surface layer modified water solution is required to make the cement and c...
