It is a new type of road environmental protection material, pervious concrete has the characteristics of water permeability and light transmission, which can effectively solve the problem of urban waterlogging and water accumulation, and reduce the blockage of natural circulation by road hardening ！
The construction method of pervious colored concrete mainly includes the following steps:
Design and preparation
Before construction can begin, requires careful design and preparation. This includes determining the required color and drainage performance according to the project requirements and environmental conditions, simultaneously planning the timing and human resources for construction, and checking the ground condition and infrastructure of the construction area.
Ground preparation
After the construction area is cleared, needs to be properly prepared for the ground. Make sure the ground is level and remove any debris and obstructions. if necessary, fill in and repair any uneven or damaged areas on the ground.
Concrete preparation
Prepare pervious concrete according to design requirements and suggestions. The color of the concrete can be adjusted by adding pigments. Ensure that the cement, stone, and mortar are mixed in the correct ratio.
Construction
After the preparation of the concrete is completed, begins construction. Use the appropriate tools and equipment to pour the concrete into the construction area, and use the leveling tool to level it. Ensure that the concrete is of uniform thickness and density.
Color treatment
In order to achieve the effect of colored pervious concrete, needs to be color treatment in the construction process. Sprinkle the colored paint over the surface of the concrete, distribute evenly with a brush or roller. Ensure that the color permeates evenly into the concrete.
Maintenance
after the completion of concrete construction, for its proper maintenance is very important. According to the concrete type and environmental conditions, take appropriate maintenance measures, to ensure the stability and durability of concrete.
Coating transparent sealer
about 3 days after the surface concrete molding and drying, brush transparent sealer, to enhance durability and aesthetics.
Prevent permeable concrete pores from fouling and plugging.
