Cement-based flexible permeable brick

Abstract

The invention discloses a cement-based flexible permeable brick, which is prepared from the following raw materials in parts by weight: 30-50 parts of rubber particles, 25-45 parts of steel slag, 15-30 parts of cement, 1.5-4 parts of bicyclopentadiene dioxide epoxy resin, 1-2 parts of a modifier, 0.3-0.8 part of a water reducing agent and 3-8 parts of water. The cement-based flexible permeable brick is relatively low in elasticity modulus, relatively good in damping and noise-reducing effects and good in frost-resistance on the premise of meeting the compressive strength and the permeability coefficient, can meet the requirements of people on the comfort level, also has good noise-reducing capacity and anti-frost property and can be applied to gardens, sidewalks and squares in large areas.

Description

technical field [0001] The invention relates to a permeable building material, in particular to a cement-based flexible permeable brick. Background technique [0002] At present, the lack of energy and water resources in the world, the expansion of desertification area and the frequent occurrence of sandstorms have made the living environment of human beings worse and worse. At present, the places where urban residents live are mainly surrounded by urban squares, commercial streets, sidewalks, community activity places, parking lots, etc., which are paved with impermeable materials such as granite, marble, glazed tiles, cement and asphalt. The urban environment is very dangerous. When it rains, the hardened ground completely prevents the rainwater from penetrating directly into the ground, and the accumulated water on the ground makes people's travel very inconvenient; the precious water resources finally flow away with the drainage pipes, which increases the burden on the ...

Problems solved by technology

When it rains, the hardened ground completely prevents the rainwater from penetrating directly into the ground, and the accumulated water on the ground makes people's travel very inconvenient; the precious water resources finally flow away with the drainage pipes, which increases the burden on the urban drainage facilities; the rainwater The large loss of rainwater makes it difficult for the groundwater level to rise, which directly affects the health of urban vegetation, makes it difficult for the surface plants in the city to grow normally, and increases the burden of municipal greening; the large loss of rainwater further aggravates the city's drought and water shortage problems, and the development of new environmental protection Building materials, it is imperative to improve and beautify the human living environment

[0003] At present, the main raw materials of some permeable bricks and permeable pavements in the field of building materials in the market are ceramics or concrete. Ceramic permeable bricks need to use a large amount of mineral resources. The mining of raw materials causes damage to the environment. The production process of ceramic permeable bricks Complex, and ceramic-based bricks consume a lot of energy when forming and sintering, high cost, low production efficiency, large investment in environmental protection, and large one-time investment scale; although the production process of concrete permeable bricks is simple, the cost is low, and no sintering is required, but The existing concrete permeable bricks have high elastic modulus, high hardness, poor comfort, poor shock absorption and noise reduction effect, and poor frost resistance
