Embodiment 1

[0030] A kind of permeable concrete is prepared by the following method:

[0031] (S1) Weigh by weight: 10 parts of acrylate water-based laminating adhesive, 1500 parts of gravel, 100 parts of superabsorbent resin microspheres, 300 parts of cement, 5 parts of polyol, 5 parts of triisopropanolamine, nano 10 parts of calcium carbonate, 1 part of nano silicon particles, 2 parts of sodium lignosulfonate, 4 parts of emulsifier, 130 parts of water;

[0032] (S2) Pour the weighed gravel, cement, nano-calcium carbonate, and nano-silicon particles into a planetary ball mill, use zircon as a ball, and grind at a revolution speed of 200 rpm for 60 minutes to make it fully mixed to obtain a mixture pink;

[0033] (S3) After mixing and stirring the weighed sodium lignosulfonate, emulsifier, polyol, triisopropanolamine and 1 / 2 water for 30 minutes, pour it into the mixed powder, stir it for 30 minutes, pour it into a weighing Take the acrylate water-based laminating adhesive, stir for 30 ...

Embodiment 2

[0035] A kind of permeable concrete, its preparation method is basically the same as embodiment 1, the difference is:

[0036] In step (S1), the proportions of raw materials used are different, and the parts of raw materials used are: 15 parts of acrylate water-based laminating adhesive, 1600 parts of gravel, 200 parts of superabsorbent resin microspheres, 400 parts of cement 7 parts of polyol, 10 parts of triisopropanolamine, 15 parts of nano-calcium carbonate, 5 parts of nano-silicon particles, 4 parts of sodium lignosulfonate, 6 parts of emulsifier, and 130 parts of water.

Embodiment 3

[0038] A kind of permeable concrete, its preparation method is basically the same as embodiment 1, the difference is:

[0039] In step (S1), the proportions of the raw materials used are different, and the parts of the raw materials used are: 12.5 parts of acrylate water-based laminating adhesive, 1550 parts of gravel, 150 parts of superabsorbent resin microspheres, 350 parts of cement 6 parts of polyol, 7.5 parts of triisopropanolamine, 12.5 parts of nano-calcium carbonate, 3 parts of nano-silicon particles, 3 parts of sodium lignosulfonate, 5 parts of emulsifier, and 145 parts of water.

Abstract

The invention discloses water-permeable concrete and a preparation method thereof. The concrete is prepared from the following components in parts by weight: 10-15 parts of acrylate water-based laminating adhesive, 1500-1600 parts of crushed stone, 100-200 parts of super absorbent resin microspheres, 300-400 parts of cement, 5-7 parts of polyol, 5-10 parts of triisopropanolamine, 10-15 parts of nano calcium carbonate, 1-5 parts of nano silicon particles, 2-4 parts of sodium lignin sulfonate, 4-6 parts of an emulsifier and 130-160 parts of water. The acrylate water-based laminating adhesive isprepared from an ethylene-acrylic emulsion, an acrylate emulsion and a cross-linking agent; the cross-linking agent comprises polyetherimide. The water-permeable concrete can improve the water permeability and the bearing capacity, is not prone to breakage and has high freezing and thawing resistance and durability.

Description

technical field [0001] The invention relates to concrete, in particular to a permeable concrete and a preparation method thereof. Background technique [0002] Permeable concrete is a kind of porous lightweight concrete made by mixing gel enhancer, aggregate, cement and water. It does not contain fine aggregate, and is bonded by a thin layer of cement slurry coated on the surface of coarse aggregate. It forms a honeycomb structure with evenly distributed pores, so it has the characteristics of air permeability, water permeability and light weight. As an environmental load-reducing concrete, the research and development of water-permeable concrete has attracted more and more attention. [0003] The existing permeable concrete has low water permeability, low overall structural strength, easy to break, poor frost resistance, and easy to break under low temperature conditions. Contents of the invention [0004] The purpose of the present invention is to provide a kind of perm...
