preparation example Construction

[0057] The preparation method of the mortar material is as follows: weighing each raw material according to the mass fraction of each raw material of the mortar surface layer; 2 Add water reducing agent and water reducing agent into the water, and stir evenly; then add the pre-mixed mixture of sand and cement, and stir to obtain the mortar material. The sand and cement are mixed in advance to facilitate their uniform mixing in the mortar material to form a mortar material with high uniformity.

[0058] The preparation method of concrete materials is as follows: weigh each raw material according to the mass fraction of each raw material at the bottom of the concrete; pour sand, recycled aggregate, natural aggregate and 70% water into a mixer, and stir evenly; then pour in cement and pulverized coal ash, and stir evenly; then add the remaining water for gelatinization and stirring; finally add a water reducing agent and stir evenly to obtain concrete materials.

Abstract

The invention discloses a nano-composite environment-friendly water permeable brick and a production method thereof. The nano-composite environment-friendly water permeable brick comprises a concrete bottom layer and a mortar surface layer arranged on the concrete bottom layer, wherein the concrete bottom layer and the mortar surface layer are compounded to form an integrated structure; the concrete bottom layer is prepared from the following raw materials in parts by weight: 20-40 parts of cement, 10-20 parts of water, 5-15 parts of fly ash, 50-65 parts of recycled aggregate, 50-65 parts of natural coarse aggregate, 65-85 parts of sand and 0.05-0.2 part of water-reducing agent; and the mortar surface layer is prepared from the following raw materials in parts by weight: 70-100 parts of cement, 5-20 parts of nano-TiO2, 30-60 parts of water, 200-400 parts of sand and 0.1-1.0 part of water-reducing agent. The nano-composite environment-friendly water permeable brick disclosed by the invention is integrally formed and has the advantages of high compressive strength, high flexural strength, good water permeability and good water retention, and a ground surface laid by the nano-composite environment-friendly water permeable bricks can timely dredge and drain rainwater, is conductive to growth of surrounding vegetation and can effectively supplement groundwater, reduce the pressure of a municipal drainage system and reduce the influence of surface gathered water on the traffic; and the nano-composite environment-friendly water permeable brick has a photocatalytic self-cleaning function and can decompose and remove organic stains on the surface of the brick and beautify the urban environment.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a nano-composite environment-friendly permeable brick and a production method thereof. Background technique [0002] Most of the raw materials used in traditional concrete pavement bricks are natural aggregates, and natural aggregates are not inexhaustible. Large-scale mining of natural aggregates will lead to a lack of rock resources and damage to the environment. At present, the ground of city squares, commercial streets, sidewalks, community activity places and other occasions are mainly paved with materials with low water permeability such as granite, marble ceramic tiles, etc. The ground made of these materials with low water permeability is impermeable to water , it will increase the burden of urban drainage facilities and affect the health of urban vegetation; and when it rains, rainwater cannot directly penetrate into the ground, resulting in ground water and m...
