Problems solved by technology

It is a kind of porous lightweight concrete made by mixing aggregate, cement and water. It does not contain fine aggregate, and the surface of coarse aggregate is covered with a thin layer of cement slurry to bond with each other to form a honeycomb shape with uniform distribution of pores. structure, so it has the characte

Embodiment 1

[0039] see figure 1 , an internal high-strength permeable concrete, including the following raw materials in parts by weight: 15 parts of ordinary portland cement, 0.2 parts of reinforcing fiber, 10 parts of granite crushed stone, 5 parts of water seepage filler, 4 parts of pebbles, porous fine 60 parts of aggregate, 2 parts of hydrophilic white carbon black, 3 parts of water, 0.5 parts of water reducer and 5 parts of internal dynamic microspheres.

[0040] One or more of carbon nanofibers, steel fibers, nylon fibers, polypropylene fibers, polyethylene fibers.

[0041] The seepage filler is made by washing and drying river sand, crushing it to 60-80 mesh, and mixing it with bentonite.

[0042] The porous fine aggregate is 40-80 mesh fine aggregate obtained by screening industrial waste slag after high-temperature smelting and calcination. The calcination temperature for high-temperature calcination is 1250-1350°C, and the calcination time is 25-35min.

[0043] The water redu...

Embodiment 2

[0050] An internal high-strength permeable concrete, comprising the following raw materials in parts by weight: 18 parts of ordinary Portland cement, 0.3 parts of reinforcing fiber, 12 parts of granite crushed stone, 6 parts of permeable filler, 6 parts of pebbles, porous fine bone 65 parts of raw material, 3 parts of hydrophilic white carbon black, 4 parts of water, 1.2 parts of water reducing agent and 6 parts of internal dynamic microspheres.

[0051] The rest are consistent with Example 1.

Embodiment 3

[0053] An internal high-strength permeable concrete, comprising the following raw materials in parts by weight: 20 parts of ordinary Portland cement, 0.4 parts of reinforcing fiber, 15 parts of granite gravel, 8 parts of water seepage filler, 8 parts of pebbles, porous fine bone 70 parts of raw material, 4 parts of hydrophilic white carbon black, 6 parts of water, 2 parts of water reducer and 8 parts of internal dynamic microspheres.

[0054] The rest are consistent with Example 1.

[0055] The invention can significantly improve the water permeability and strength of the permeable concrete by improving the raw materials of the permeable concrete, introducing reinforcing fibers, water-permeable fillers, porous fine aggregates and hydrophilic silica, and innovatively introducing internal moving microspheres Pre-embedded in pervious concrete, on the one hand, it can act as part of the coarse aggregate, which can not only increase the porosity of pervious concrete, but also assis...

Abstract

The invention discloses internal-moving type high-strength pervious concrete, belongs to the technical field of building materials, and aims at remarkably improving the water permeability and strength of the pervious concrete by improving the raw materials of the pervious concrete and introducing reinforcing fibers, a water seepage filler, porous fine aggregate and hydrophilic white carbon black. Meanwhile, the internal moving microspheres are innovatively introduced and pre-buried into the pervious concrete; on the one hand, the internal moving microspheres can serve as part of coarse aggregate, the porosity of the pervious concrete can be improved, and the strength of the pervious concrete can be improved in an auxiliary mode; on the other hand, dynamic change can be achieved by controlling the water permeation speed; by means of migration of the vibration guiding balls in the inner moving microspheres, static permeation in existing pervious concrete is converted into a dynamic form of internal vibration, overall acceleration is conducted on water permeation in the pervious concrete, the drainage efficiency can be greatly improved, and the good service life is kept.

Description

technical field [0001] The invention relates to the technical field of building materials, more specifically, to an internal-moving high-strength 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 pavement emphasizes the durability and usability of the ground, but the impermeability of this pavement completely blocks the precious natural precipitation from the underlying soil and groundwater, and most of the precipitation passes through the urban drainage system The discharge of the pipe network into surface water sources such as rivers, lakes and seas, coupled with the excessive extraction of urban groundwate...
