Problems solved by technology

Due to the different geographical conditions and ages of natural stone, the weather resistance and color of the material are also different, and the processing and transportation costs are also high, and there are more wastes from cutting or chipping, especially processing special-shaped curbs. , and the cost is higher
Especially for curbs and gutters made of cement concrete, when it snows, it is usually necessary to sprinkle salt on the road surface to prevent the road from freezing, but salt will seriously corrode the calcareous curbstones, making them weathered and deteriorated and shortening their lifespan

Abstract

The invention is a method making curb stone and drainage tank. The technical project as follows: use magnesia as gelatinizing agent, magnesium-chloride water solvent as solidifying one, and sand, mine waste residue, stone scraps and fiber material as aggregate, fill reinforced denaturing agent, coloring agent and waterproof agent, stir in a certain proportion to make denatured magnesium-oxygen concrete, shape by mould press or extrusion and maintain to make the finished product which can be used to separate road, drainage and slope protection placed on two sides of road, railroad and street and used as decorative stone material.

Description

1. Technical field [0001] The invention provides a method for manufacturing artificial stone in the field of building materials, in particular a method for manufacturing curb stones and drains. 2. Background technology [0002] Curb stone is a stone set on both sides of highways, railways and urban roads to isolate the pavement. It is usually made of natural stone into a certain geometric shape by chiseling or mechanical cutting, generally a cuboid. According to the different materials selected, there are granite, basalt, volcanic rock, limestone and so on. Due to the different geographical conditions and ages of natural stone, its weathering resistance and color are also different, and the processing and transportation costs are also high, and there are more wastes cut or chiseled, especially the processing of special-shaped curbs is more difficult. , and the cost is higher. Especially for the curbs and gutter made of cement concrete, when it snows, it is usually necessa...
