Permeable concrete is also known as porous concrete, sandless concrete or permeable floor. It is a lightweight porous concrete mixed with aggregates, cement, reinforcements and water and does not contain fine aggregates. Its unique feature is its honeycomb structure, which is formed by covering the surface of coarse aggregate with a thin layer of cement slurry, making the interior of the concrete filled with uniform pores. Therefore, permeable concrete is not only breathable and water-permeable, but also very lightweight. Mixing of concrete materials
First, mix the special cement for permeable concrete, gravel, water and other materials. Note that water should be added in 2 to 3 times to ensure the quality of the concrete. Ground moisture treatment
The second step is to ensure that the ground is moist, which is the key to laying permeable concrete. If the ground is too dry, sprinkle some water. Breathable and water-permeable treatment
Use a low-frequency vibrator to treat the concrete surface while leaving certain gaps, which can make the concrete more breathable and water-permeable. Use of rollers
Use a light roller to roll the concrete floor to make it stronger and more durable. Characteristics of permeable concrete
Permeable concrete is not only air-permeable and water-permeable, but also very lightweight. While meeting strength requirements, permeable concrete also needs to maintain certain through-holes to meet water permeability. Application of environmentally friendly materials
Permeable concrete is an environmentally friendly material that can make cities more environmentally friendly, breathable and water-permeable, and provide better conditions for green travel.
