Embodiment Construction

[0015] A sintered permeable floor tile with high porosity and strength, prepared from the following raw materials in parts by weight (kg): sewage plant sludge 40, rice husk 6, potassium feldspar powder 4, fly ash 10, water glass 10, basalt crushed Stone 29, sawdust 5, mesoporous silica 9, silane coupling agent kh5600.8, polyvinyl alcohol fiber 3, blast furnace slag 7, chemical waste gypsum powder 2.

[0016] The sintered permeable floor tile with high porosity strength is made by the following specific steps:

[0017] (1) Naturally dry the sludge from the sewage plant, pulverize and pass through a 200-mesh sieve to obtain sludge powder for use; mix half of the sludge powder, rice husk, and potassium feldspar powder, add an appropriate amount of water, and put it into a mixer Stir at a speed of 120 rpm to form sludge, control the water content to 20%, and then send it to a granulator for extrusion and granulation to obtain sludge granules, and control the particle size to 10 me...

Abstract

The invention discloses a multi-pore high-strength sintering permeable floor brick. The multi-pore high-strength sintering permeable floor brick is prepared from, by weight, 40-43 parts of sewage plant sludge, 6-7 parts of rice hulls, 4-5 parts of potassium feldspar powder, 10-12 parts of fly ash, 10-12 parts of water glass, 29-31 parts of basalt rubble, 5-6 parts of sawdust, 9-11 parts of mesoporous silica, 0.8-1 part of a silane coupling agent kh560, 3-4 parts of polyvinyl alcohol fibers, 7-9 parts of blast furnace slag and 2-3 parts of chemical waste gypsum powder. According to the multi-pore high-strength sintering permeable floor brick, the mesoporous silica, the sawdust and the polyvinyl alcohol fibers are added in preparation of the brick, and a composite through hole structure can be formed through sintering molding after technological modification; in addition, multiple pores distributed densely are obtained by reasonably regulating the particle size of mixed aggregates; meanwhile, the product is high in compressive strength, firm, durable and high in permeable coefficient.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sintered permeable floor tile with high porous strength. 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 can ...
