Abrasion-resistant and anti-fracturing sintered water-permeable floor tile

Abstract

The invention discloses an abrasion-resistant and anti-fracturing sintered water-permeable floor tile. The abrasion-resistant and anti-fracturing sintered water-permeable floor tile is prepared from, by weight, 40-43 parts of sludge from a wastewater treatment plant, 6-7 parts of rice hulls, 4-5 parts of potassium feldspar powder, 10-12 parts of coal ash, 10-12 parts of water glass, 12-14 parts of josephinite slag, 3-4 parts of quick lime, 1-1.5 parts of rosin soda soap, 10-12 parts of rubing grain clinker, 3-4 parts of chromic oxide, 3-4 parts of EVA emulsion, 8-10 parts of kaolin and 4-5 parts of plant ash. Josephinite slag, rubing grain clinker, chromic oxide and other ingredients are used and added to preparation of a green brick through a certain process, the anti-fracturing and anti-pressing strength, abrasion resistance and comprehensive performance of the prepared green brick are guaranteed through sintering, meanwhile, waste resources are adopted, production cost is reduced, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a wear-resistant and anti-bending sintered permeable floor tile. 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, whic...

Problems solved by technology

[0005] In recent years, with the increase of nickel production, the discharge and storage of ferronickel slag have also increased. According to statistics, the annual discharge of ferronickel slag in the country has reached tens of millions of tons, and the comprehensive utilization rate of resources is less than 8%.

Most smelters in the non-ferrous metal industry at home and abroad use ferronickel slag to open-air stockpiles or solidify backfill mines. Open-air stockpiling not only occupies arable land and pollutes the environment, but also harmful substances in ferronickel slag will penetrate into the soil with rainwater washing, causing Pollution of surface water and groundwater sources, destroying the ecological environment

It also causes waste of enterprise resources and increases production costs.
