Embodiment 1

[0054] Preparation method of gel reinforcement:

[0055] Weighing: 100 kg of cement; 250 kg of silica; 50 kg of polyvinyl alcohol; 25 kg of redispersible latex powder (VAE); 10 kg of brightener; 10 kg of water reducing agent; 15 kg of lignin fiber. The gel reinforcing material of the present invention can be obtained by stirring and mixing the above raw materials evenly.

[0056] The water reducer is the model PC-1030 defoaming polycarboxylate water reducer produced by Suzhou Xingbang Chemical Building Materials Co., Ltd.

[0057] The brightener is bright powder produced by Suzhou Xingbang Chemical Building Materials Co., Ltd.

[0058] Preparation method of high service life permeable concrete:

[0059] Add 0.4 kg of emulsion (i.e. SD-818 emulsion for real stone paint) into 3.6 kg of water and stir to mix evenly to obtain an emulsified reactant;

[0060] Add 1600 kg of basalt crushed stones, 320 kg of 42.5 gray cement, 15 kg of the gel reinforcement prepared above, 4 kg of ...

Embodiment 2

[0064] Basically the same as Example 1, the difference is: the water reducer is composed of 2,7-dihydroxynaphthalene-3,6-sodium disulfonate and 2,6-di-tert-butylnaphthalene sodium sulfonate according to the mass ratio of 1: 1 blended.

[0065] The brightener is oleic acid diethanolamine salt.

Embodiment 3

[0067] It is basically the same as Example 1, the only difference is that the water reducer is mixed with sodium tris(1-methylethyl)naphthalenesulfonate and sodium 2,6-di-tert-butylnaphthalenesulfonate in a mass ratio of 1:1 made.

[0068] The brightener is oleic acid diethanolamine salt.

Abstract

The invention discloses long-life permeable concrete and a production method thereof; the long-life permeable concrete is produced from, by weight, 1000-2000 parts of gravel, 150-400 parts of cement, 10-30 parts of gel reinforcing material, 0.2-1 part of emulsion, 400-1000 parts of water, and 0-12 parts of a colorant. The long-life permeable concrete provided herein has good compressive strength and high permeation coefficient, can meet the need of various projects for concrete permeability, is helpful for maintaining ecological balance and implementing sustainable development, is good in decoration effect, easy to maintain, high in freeze-thaw resistance, high in radiating property and high in bearing capacity, enables urban ecological environment to be effectively improved, is highly ecologically friendly and has a long life up to 8 years and longer.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a high-service life permeable concrete and a preparation method thereof. Background technique [0002] With the continuous prosperity and development of the world economy, the earth has gradually changed its original appearance. Urban construction is changing with each passing day and developing rapidly, and at the same time, people are surrounded by the world of reinforced concrete. Public buildings, residences, and road construction harden the surface environment, almost completely changing the ecological environment of the construction site, and the atmospheric evaporation cycle is affected, resulting in a decrease in air humidity and an increase in temperature in the urban area, forming a "heat island effect", and greening such as urban green spaces This phenomenon is also exacerbated by the absence of This "heat island effect" makes the city hotter and hotter in summer, and the dus...
