A method of manufacturing concrete pavement bricks with a surface layer

Abstract

The invention relates to a manufacturing method of a concrete pavement brick with a surface course. The manufacturing method of the concrete pavement brick with the surface course is characterized in that a surface course brick body and a base course brick body are included, and concretely comprises the following steps that 1, the base course brick body is made from concrete and gravel, wherein the component ratio between the concrete and the gravel is 1-1.5:1 and the concrete and the gravel are made through vibration compression; 2, the base course brick body is warmed and preheated and the temperature is maintained for 2-5 minutes; 3, primer is evenly sprayed on the surface of the base course brick body; 4, the surface course brick body is manufactured above the primer, wherein the surface course brick body is made of cement, coarse sand, silica fume and emulsion; meanwhile, a curing agent is added in the manufacturing process of the surface course brick body; 5, the surface course brick body is warmed and the temperature is maintained for 3-5 minutes. By applying the manufacturing method of the concrete pavement brick with the surface course, the color and lustre of the pavement brick is improved, the pavement brick can have long service life in the complicated external environment and is resistant to water erosion and wind decay, thus the high temperature resistance and anti-friction properties of the pavement brick are improved, the pavement brick can maintain the original color for a long time, and the pavement brick is prevented from being frosted.

Description

technical field [0001] The invention relates to the technical field of concrete pavement bricks, in particular to a method for manufacturing a concrete pavement brick with a surface layer. Background technique [0002] Concrete pavement bricks in the prior art use cement and stones as the main raw materials, and are processed, pressurized or other molding processes to make concrete pavement bricks of various shapes. Concrete pavement bricks are mainly used for laying urban roads, sidewalks, and city squares. Blocks, slabs, etc. for concrete pavement and ground engineering. Due to long-term exposure of pavement bricks to complex external environments, water erosion, wind corrosion, temperature changes, friction and other reasons, it is easy to make them lose their original color and aesthetics, and the construction quality cannot be guaranteed, and the use of pavement bricks number of years. Contents of the invention [0003] An object of the present invention is to overc...
