Embodiment 1

[0032] Environmentally friendly permeable concrete raw materials (parts by weight): 100 parts of P.O 42.5 cement, 500 parts of granite gravel, 14 parts of poly(vinyl acetate) emulsion, 5.4 parts of water reducing agent, 18 parts of nanocomposite filler, and 31 parts of water.

[0033] The water reducer is composed of three (1-methylethyl) sodium naphthalenesulfonate, sodium 6-hydroxy-2-naphthalenesulfonate, and sodium 2,6-di-tert-butylnaphthalenesulfonate in a mass ratio of 1: 1:1 Stir and mix to get even.

[0034] The nanocomposite filler is obtained by uniformly stirring and mixing titanium phosphate, copper tungstate and copper oxalate in a mass ratio of 1:1:1.

[0035] Preparation of environmentally friendly permeable concrete: Add water reducer and poly(vinyl acetate) emulsion into water and mix well to obtain a mixed solution; add P.O 42.5 cement, granite gravel, and nanocomposite fillers into a concrete mixer and mix well, then Add the mixture and continue to stir unti...

Embodiment 2

[0037] It is basically the same as Example 1, except that the water reducer is mixed with 6-hydroxy-2-naphthalene sodium sulfonate and 2,6-di-tert-butylnaphthalene sodium sulfonate in a mass ratio of 1:1 Get even. The environmental protection permeable concrete of embodiment 2 is obtained.

Embodiment 3

[0039] Basically the same as Example 1, the only difference is that the water reducer is composed of three (1-methylethyl) sodium naphthalene sulfonate and 2,6-di-tert-butylnaphthalene sodium sulfonate in a mass ratio of 1: 1 Stir to mix evenly to obtain. The environmental protection permeable concrete of embodiment 3 is obtained.

Abstract

The invention discloses environmental-friendly water permeability concrete. The environmental-friendly water permeability concrete is prepared from the following raw materials in parts by weight: 95-105 parts of cement, 440-540 parts of granite macadam, 12-22 parts of a polyvinyl acetate emulsion, 1-10 parts of a water reducing agent, 10-30 parts of a nanometer composite filler, and 28-38 parts of water. According to the environmental-friendly water permeability concrete provided by the invention, through a reasonable compounding ratio, the kinds and the consumption of the water reducing agent, and the kinds and the consumption of the nanometer composite filler, which are suitable for the environmental-friendly water permeability concrete are preferably selected. The water permeability concrete has favourable compressive strength and favorable permeability coefficients, can meet various engineering requirements for permeability of the concrete, facilitates maintenance of ecological balance and realizes sustainable development.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to an environment-friendly 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 groundwater, has led to lower and ...
