Embodiment 1

[0071] Mix and stir 4.5kg of concrete coarse aggregate, 3.0kg of concrete fine aggregate, 1.8kg of cement, 0.68kg of water, and 0.02kg of powdered polycarboxylate superplasticizer to obtain a uniformly stirred slurry.

[0072] Among them, the concrete coarse aggregate and concrete fine aggregate come from the mixture of waste mortar blocks and waste bricks. The waste mortar blocks and waste bricks are crushed and screened by a jaw crusher, and the concrete coarse aggregate and concrete fine aggregate are obtained by secondary screening respectively. Concrete fine aggregate, the particle size of concrete coarse aggregate is 5-15mm, the particle size of concrete fine aggregate is not more than 4.75mm,

[0073] Divide the obtained uniform slurry into two pours. After pouring the first layer, insert and tamp 25 times, then manually pressurize with a pressure head (15cm×15cm×15cm concrete test block), and insert and tamp 25 times after pouring the second layer. Then use the indente...

Abstract

The invention provides a water-permeable pavement structure and a water-permeable pavement process, and belongs to the technical field of water-permeable bricks. The water-permeable pavement structurecomprises a surface layer which is a water-permeable brick and comprises the following raw materials, based on the weight of the surface layer being 1, in percentage by weight: 38-45% of concrete coarse aggregate, 30-35% of concrete fine aggregate, 18-22% of cement, 6-7% of water and 0.15-0.22% of powdery polycarboxylate superplasticizer; wherein the concrete coarse aggregate is particles with the particle size larger than 4.75 mm and not larger than 31 mm, and the concrete fine aggregate is particles with the particle size not larger than 4.75 mm; the concrete coarse aggregate and the concrete fine aggregate are aggregate obtained by recycling construction waste. The water permeable brick is prepared from the concrete regenerated from the waste garbage, so that the reduction of the wasteconstruction garbage is realized, the environment is protected, the energy is saved, the porosity is high, the water absorbability is strong, the water permeability is high, the compressive strengthcan reach 30 MPa or above, and the compressive strength is high.

Description

technical field [0001] The invention relates to the technical field of permeable bricks, in particular to a permeable brick prepared from recycled construction waste aggregates and a preparation process thereof. Background technique [0002] Permeable bricks originated in the Netherlands and were quickly promoted. At present, my country's permeable bricks are divided into two categories, one is based on solid industrial waste, domestic garbage and construction waste, and is a building decoration material with water permeable performance and meeting the standards of permeable bricks through crushing, forming, and high-temperature refining. , called ceramic permeable bricks; the other type is a building decoration material with the performance of permeable bricks and meeting the standards of permeable bricks, which is made of inorganic metal materials as the main raw material and formed and solidified by organic or inorganic binders. It does not need to be fired, so it is calle...
