Embodiment 1

[0023] The embodiment of the present invention discloses an environment-friendly permeable concrete, which is prepared from the following raw materials with the following optimal weight ratio: 245 parts of waste concrete aggregate, gypsum powder 168 parts, 132 parts of cement, 46 parts of ferrochrome slag powder, 42 parts of silica fume, 23 parts of nano filler and 5 parts of polycarboxylate superplasticizer;

[0024] Among them, the waste concrete aggregate is crushed from the waste concrete, and manually sieved to remove large particles and gravel impurities, washed with water to remove the clay, dust and gravel and other impurities adhered to the aggregate itself, dried, and then further sieved into granules The diameter range is 3.23mm recycled fine aggregate and 5.68mm recycled coarse aggregate; the weight ratio of recycled fine aggregate to the recycled coarse aggregate is 1:4; the nano filler is titanium phosphate and copper tungstate, the mass ratio It is 1:1.

Embodiment 2

[0026] The embodiment of the present invention discloses an environment-friendly permeable concrete, which is prepared from the following raw materials with the following optimal weight ratio: 210 parts of waste concrete aggregate, gypsum powder 152 parts, 108 parts of cement, 40 parts of ferrochrome slag powder, 30 parts of silica fume, 10 parts of nano filler and 2 parts of polycarboxylate superplasticizer;

[0027] Among them, the waste concrete aggregate is crushed from the waste concrete, and manually sieved to remove large particles and gravel impurities, washed with water to remove the clay, dust and gravel and other impurities adhered to the aggregate itself, dried, and then further sieved into granules The diameter range is 2.36mm recycled fine aggregate and 4.75mm recycled coarse aggregate; the weight ratio of recycled fine aggregate and the recycled coarse aggregate is 1:4; the nano filler is titanium phosphate and copper oxalate, and the mass ratio is 1:3.

Embodiment 3

[0029] The embodiment of the present invention discloses an environment-friendly permeable concrete, which is prepared from the following raw materials with the optimal weight ratio: 305 parts of waste concrete aggregate, 183 parts of gypsum powder, 155 parts of cement, and 50 parts of ferrochrome slag powder , 50 parts of silica fume, 32 parts of nano filler and 10 parts of polycarboxylate superplasticizer;

[0030] Among them, the waste concrete aggregate is crushed from the waste concrete and manually sieved to remove large particles and gravel impurities, washed with water to remove the clay, dust and gravel and other impurities adhered to the aggregate itself, dried, and then further sieved into granules The diameter range is 4.75mm recycled fine aggregate and 9.5mm recycled coarse aggregate; the weight ratio of recycled fine aggregate to the recycled coarse aggregate is 1:4; the nanometer filler is copper oxalate and copper tungstate, the mass ratio It is 2:3.

Abstract

The invention discloses a pervious concrete, which is prepared from the following raw materials by weight: 210-305 parts of waste concrete aggregate, 152-183 parts of gypsum powder, 108-155 parts of cement, 40-50 parts of ferrochrome slag powder, 30-50 parts of silica fume, 10-32 parts of nano-filler and 2-10 parts of a water reducing agent. The environment-friendly pervious concrete provided by the invention is prepared with industrial waste as the main raw material, avoids the pollution of industrial waste to the environment, and at the same time saves grit stone, land and other natural resources.

Description

technical field [0001] The invention relates to the technical field of concrete, and more specifically relates to a kind of permeable concrete. Background technique [0002] In the process of urbanization, the surface of modern cities is gradually hardened and covered by water-blocking materials such as buildings and concrete, forming an ecological "artificial desert". At the same time of great convenience, these impermeable pavements also have a great negative impact on the ecological environment of the city. First of all, the traditional ground pavement emphasizes the durability and usability of the ground, but this kind of pavement is impermeable, completely blocking the natural precipitation from the underlying soil and groundwater, and most of the precipitation is discharged into rivers and lakes through the urban drainage system pipe network In surface water sources such as the sea, coupled with the excessive extraction of urban groundwater, the urban groundwater leve...
