Problems solved by technology

[0004] However, when this kind of concrete is used, especially in rainy weather, it does not directly contact the soil on the surface, resulting in poor air permeability and water permeability, and cannot replenish groundwater, alleviate some urban environmental problems such as the sharp decline of groundwater in the city, and also lead to underground subsidence

Abstract

The invention provides pervious concrete and a preparation method thereof. The content of each component in raw materials is as follows: 21-34 parts of ore coarse aggregates, 23-27 parts of fine sand,17-24 parts of Portland cement, 16-23 parts of diatomite, 13-17 parts of a polymer cementing material, 2-4 parts of phosphorus slag fine powder, 1-3 parts of iron powder, 8-13 parts of phenolic fibers and 6-15 parts of polypropylene fibers. Through the preparation by using the preparation method, the adhesion degree of all the components in the raw materials can be enhanced; gaps are generated between the phenolic fibers and the polypropylene fibers, and facilitate water permeation; and the pervious concrete can be further promoted in the actual building industry.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a permeable concrete and a preparation method thereof. Background technique [0002] With the continuous development of the current social economy, people's living standards are also constantly improving, and the pursuit of quality of life is also getting higher and higher. [0003] Especially for the construction industry, due to the gradual expansion and improvement of urban modernization, the use of concrete is becoming more and more extensive. The surface and ground buildings of modern cities are gradually covered by reinforced concrete, which can keep the ground clean. [0004] However, when this kind of concrete is used, especially in rainy weather, it does not directly contact the soil on the surface, resulting in poor air permeability and water permeability, and cannot replenish groundwater, alleviate some urban environmental problems such as the sharp decline of groundw...
