Porous high-water-seepage permeable floor tile doped with waste ash

Abstract

The invention discloses a porous high-water-seepage permeable floor tile doped with waste ash. The floor tile is prepared from, by weight, 40-43 parts of sludge of a sewage plant, 6-7 parts of rice hull, 4-5 parts of potassium feldspar powder, 10-12 parts of flyash, 10-12 parts of sodium silicate, 12-14 parts of the waste ash, 18-20 parts of abandoned ceramics, 5-7 parts of quartz sand, 2-3 parts of methyl methacrylate, 2-3 parts of redispersible rubber powder, 1.5-2 parts of ammonium carbonate and 4-5.5 parts of papermaking black liquid. The abandoned ceramics, the waste ash, the quartz sand and the like are added as aggregate and matched with binding agents such as the redispersible rubber powder and methyl methacrylate to prepare tile adobe with good plasticity, as continuous through holes are formed in a tile body through sintering, the floor tile has high permeability, and meanwhile high bending strength and high compressive strength are reserved. The raw materials of the prepared product are wide in source, low in cost and beneficial for protecting mineral resources and ecological resources.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a porous and highly permeable floor tile mixed with garbage and ash. 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, ...

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
