Embodiment 1

[0032] Nano-reinforced permeable concrete raw materials (parts by weight): 100 parts of P.O 42.5 cement, 500 parts of basalt crushed stone, 8 parts of styrene-butadiene latex, 5.4 parts of water reducing agent, 18 parts of nanocomposite filler, and 33 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 nano-reinforced permeable concrete: Add water reducer and styrene-butadiene latex into water and mix well to obtain a mixed solution; add P.O 42.5 cement, basalt gravel, and nanocomposite fillers to a concrete mixer and mix evenly, then add the mixed solution Continue to stir until the mixture is unif...

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 nano-reinforced permeable concrete of Example 2 was 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 nano-reinforced permeable concrete of Example 3 was obtained.

Abstract

The invention discloses nano-reinforcement water-permeable concrete. The concrete is prepared from, by weight, 95-105 parts of cement, 440-540 parts of broken basalt, 1-10 parts of styrene-butadiene latex, 1-10 parts of water reducer, 10-30 parts of nano composite filler and 28-38 parts of water. According to the nano-reinforcement water-permeable concrete, the variety and the amount of water reducer and nano composite filler suitable for the nano-reinforcement water-permeable concrete are selected according to a reasonable ratio. The water-permeable concrete is good in compressive strength and permeability coefficient, can meet the demand of various projects with the requirement for water permeability of concrete, ecological balance is easily maintained, and sustainable development is achieved.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a nano-reinforced 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 lower ...
