Embodiment 1

[0022] In this embodiment, the corrosion-resistant permeable brick is composed of 20wt% P.O42.5 cement, 1.2wt% anhydrite powder, 18.0wt% slag pellets, 12.0wt% hollow microspheres, 1.5 wt% admixture, and the balance of quartz sand. Wherein, the admixture contains: 20wt% water glass (modulus 2.2~2.5), 12.0wt% alkylphenol ether sulfosuccinate, 15.0wt% lignosulfonate, 3.0wt% γ-acryloxypropyltrimethoxysilane, 2.0wt% triglycidyl isocyanurate, 1.5wt% sodium dihydrogen phosphate, and the balance diethanolamine.

Embodiment 2

[0024] In this embodiment, the corrosion-resistant permeable brick is composed of 25wt% P.O42.5 cement, 1.0wt% anhydrite powder, 15.0wt% slag pellets, 10wt% hollow microspheres, 2.1wt% % of admixture, and the balance of quartz sand. Wherein, the admixture contains: 25wt% water glass (modulus 2.2~2.5), 15.0wt% alkylphenol ether sulfosuccinate, 12.0wt% lignosulfonate, 5.0wt% γ-methacryloxypropyltrimethoxysilane, 1.5wt% triglycidyl isocyanurate, 1.0wt% sodium dihydrogen phosphate, and the balance diethanolamine.

Embodiment 3

[0026] In this example, the corrosion-resistant permeable brick is composed of 22wt% P.O42.5 cement, 1.2wt% anhydrite powder, 18.0wt% slag pellets, 12wt% hollow microspheres, 1.8wt% % of admixture, and the balance of quartz sand. Wherein, the admixture contains: 22wt% water glass (modulus 2.2~2.5), 13.5wt% alkylphenol ether sulfosuccinate, 13.2wt% lignosulfonate, 4.0wt% γ-methacryloxypropyltrimethoxysilane, 1.8wt% triglycidyl isocyanurate, 1.2wt% sodium dihydrogen phosphate, and the balance diethanolamine.

Abstract

The present invention relates to a corrosion resistant water permeable brick, and belongs to the technical field of building materials. The corrosion corrosion resistant water permeable brick comprises 20-25wt% of Portland cement, 1.0-1.2wt% of anhydrite powder, 15.0-20.0wt% of slag pellets, 10-12wt % of cenospheres, 1.5-2.1wt% of admixtures, and the balance of quartz sand. Under the premise that the porosity and water permeability coefficient of the corrosion resistant water permeable brick are significantly higher than that of a water permeable brick, the compressive strength of the corrosion resistant water permeable brick is still higher than that of the conventional water permeable brick, the corrosion resistant water permeable brick has good corrosion resistance, and service life is significantly increased.

Description

technical field [0001] The invention belongs to the technical field of building materials, and more specifically, the invention relates to a corrosion-resistant permeable brick. Background technique [0002] Most of the urban sidewalks are paved with bricks to maintain the appearance and smoothness. Most of the bricks laid on the existing sidewalks are pressed with clay and then directly sintered into shape. Their water permeability is poor. On the one hand, it blocks the replenishment of groundwater by rainwater On the other hand, due to poor drainage of rainwater, it is also easy to cause urban waterlogging. [0003] In order to solve the above problems, permeable brick products have been introduced in the prior art. At present, the permeable bricks on the market can be roughly divided into three basic types: ceramic permeable bricks, cement-based permeable bricks and resin-bonded permeable bricks. Although ceramic permeable bricks have the advantages of high hardness, h...
