Sintered water permeable brick with smooth and mildew-proofing surface

Abstract

The invention discloses a sintered water permeable brick with a smooth and mildew-proofing surface. The water permeable brick is prepared from the following raw materials in parts by weight: 40-43 parts of sludge of a sewage plant, 6-7 parts of rice husks, 4-5 parts of potassium feldspar powder, 5-6 parts of pulverized fuel ash, 3-4 parts of bamboo powder, 8-10 parts of activated pozzolana, 19-21 parts of fluorite tailings, 4-5 parts of noan-silicon carbide, 2-3 parts of sodium carboxymethyl cellulose and 3-4 parts of light magnesium oxide. According to the sintered water permeable brick, the fluorite tailings, palm fibers, nano-silicon carbide and other ingredients are added to serve as aggregate ingredients of a brick blank, so that the tensile strength and crack resistance of a brick body can be enhanced, and the porosity of the brick body is further improved; the bamboo powder added into the brick is turned into a bamboo charcoal ingredient by means of sintering, so that the water permeable brick has excellent antibacterial and mildew-proofing effect. The manufactured water permeable brick has an attractive appearance and smooth surface, and integrates strength, water permeability and corrosion resistance into a whole.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sintered permeable brick with a smooth surface and no mildew. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. use. In the process of sponge city construction, the systematic nature of natural precipitation, surface water and groundwater should be coordinated, water supply, drainage and other water recycling links should be coordinated, and its complexity and long-term nature should be considered. As we all know, most of the existing urban street pavements are paved with impermeable materials such as cement concrete, asphalt, stone, and ceramic tiles. This hardened pavement is no longer suitable for the trend of building sponge city pavements. [0003] Permeable bricks have good water permeability and moisturizing properties, which...

Problems solved by technology

Sludge landfill cannot fundamentally solve the problem of sludge pollution to the environment, and the cost of sludge regeneration and recycling is very high, so the resource utilization of sludge is considered to be the most economical and reasonable disposal method
