Embodiment 1

[0023] This embodiment provides a colored permeable concrete, which is made of the following components by weight: granite stone: 600 parts; admixture: 8 parts; cement: 200 parts; toner: 10 parts; water: 50 parts; Among them, the ingredients of the admixture are: 5% of fiber, 7.5% of rubber powder, 12% of silicon powder, 2% of water reducing agent, 35% of corundum, and 38.5% of quartz powder.

[0024] The preparation method of described colored permeable concrete comprises the following steps:

[0025] A. Mix the above-mentioned granite stone rice and the toner in the above parts by weight, add 40% of the above-mentioned water by weight after mixing evenly, and continue to stir evenly to obtain a mixture;

[0026] B, the cement of 40% by weight and the admixture of 40% by weight and the water of 30% by weight are stirred for 30s, obtain the first cement slurry;

[0027] C, adding the first cement slurry obtained in step B into the mixture obtained in step A, stirring for 1 mi...

Embodiment 2

[0033] This embodiment provides a colored permeable concrete, which is made of the following components by weight: granite stone: 600 parts; admixture: 8 parts; cement: 200 parts; toner: 10 parts; water: 50 parts; Among them, the ingredients of the admixture are: 5.5% of fiber, 7% of rubber powder, 10% of silicon powder, 4% of water reducing agent, 37.5% of corundum, and 36% of quartz powder.

[0034] Others are the same as embodiment 1

Abstract

The invention provides colored concrete and a preparation method thereof. The colored concrete is prepared from 500-650 parts of granite stone grains, 7-10 parts of an admixture; 180 to 250 parts of cement; 9 to 12 parts of toner; and 40 to 70 parts of water. The admixture comprises the following components in percentage by mass: 5%-7% of fibers, 6.2%-6.7% of rubber powder, 10%-12% of silicon powder, 2.9%-3.2% of a water reducing agent, 36.1%-36.7% of carborundum and 35%-40% of quartz powder; according to the preparation method of the colored pervious concrete, the cement paste formed by the cement and the admixture is mixed with the aggregate in three times, so that the water permeability and the strength of the colored pervious concrete are improved. The colored pervious concrete is goodin water permeability, strength, frost resistance and other properties, long in service life and suitable for being applied to actual engineering.

Description

technical field [0001] The invention relates to the preparation technology of permeable concrete, in particular to a colored permeable concrete and a preparation method thereof. Background technique [0002] As a construction material, concrete is widely used in infrastructure and various buildings due to its many advantages such as ease of material supply, freedom of forming, and durability, and has made a great contribution to social development. But because of this, the original natural vegetation and bare soil are gradually hardened and covered by water-blocking materials such as buildings and concrete. Due to the lack of breathability of dense ordinary concrete, the ability to penetrate rainwater is poor, so that rainwater cannot penetrate into the ground. Puts a lot of pressure on the drainage system of the road surface. Colored permeable concrete, also known as porous concrete, can also be called drainage concrete. It has a certain degree of water permeability, which...
