Example Embodiment

[0053] Example 1

[0054] Preparation method of gel reinforcement:

[0055] Weigh: 100 kg of cement; 250 kg of silicon dioxide; 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. Stir and mix the above-mentioned raw materials uniformly to obtain the gel reinforcing material of the present invention.

[0056] The water reducing agent is a model PC-1030 defoaming polycarboxylic acid water reducing agent produced by Suzhou Xingbang Chemical Building Materials Co., Ltd.

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

[0058] Preparation method of permeable concrete with long service life:

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

[0060] Add 1,600 kilograms of basalt gravel, 320 kilograms of 42.5 gray cement, 15 kilograms ...

Example Embodiment

[0063] Example 2

[0064] It is basically the same as Example 1, except that the water reducing agent consists of 2,7-dihydroxynaphthalene-3,6-disulfonate sodium and 2,6-di-tert-butylnaphthalenesulfonate in a mass ratio of 1: 1 mixed.

[0065] The brightener is oleic acid diethanolamine salt.

Example Embodiment

[0066] Example 3

[0067] It is basically the same as Example 1, except that the water reducing agent is mixed with sodium tris (1-methylethyl) naphthalene sulfonate and sodium 2,6-di-tert-butyl naphthalene sulfonate in a mass ratio of 1:1 Become.

[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...
