Embodiment 1

[0019] The concrete steps of the transformation method of a kind of porous vegetation concrete pore alkalinity are as follows:

[0020] (1) Preparation of spray solution

[0021] According to the weight ratio configuration of epoxy resin: ethylenediamine curing agent: acetone diluent is 100:10:50, after fully mixing epoxy resin, ethylenediamine and acetone and stirring evenly, the epoxy resin is prepared Spray solution.

[0022] (2) Spray film formation

[0023] After step (1) is completed, the epoxy resin spray solution prepared in step (1) is injected into the spray equipment, and then the formed ordinary Portland cement porous vegetation concrete is sprayed, and the spraying is repeated once. Make the epoxy resin spray solution form a polymer film on the inner surface of the pores to isolate the seepage of alkaline substances on the inner wall of the pores, thereby reducing the alkalinity in the pores and ensuring the strength of the concrete.

Embodiment 2

[0027] The concrete steps of the transformation method of a kind of porous vegetation concrete pore alkalinity are as follows:

[0028] (1) Preparation of spray solution

[0029] According to the configuration of epoxy resin: phenolic modified ethylenediamine curing agent: the weight ratio of ethyl acetate diluent is 100: 25: 100, epoxy resin, phenolic modified ethylenediamine, ethyl acetate are fully mixed, After stirring evenly, the epoxy resin spray solution is prepared.

[0030] (2) Spray film formation

[0031] After step (1) is completed, the epoxy resin spray solution prepared in step (1) is injected into the spray equipment, and then the formed ordinary Portland cement porous vegetation concrete is sprayed, and the spraying is repeated 2 times. Make the epoxy resin spray solution form a polymer film on the inner surface of the pores to isolate the seepage of alkaline substances on the inner wall of the pores, thereby reducing the alkalinity in the pores and ensuring ...

Embodiment 3

[0035] The concrete steps of the transformation method of a kind of porous vegetation concrete pore alkalinity are as follows:

[0036] (1) Preparation of spray solution

[0037] According to the ratio configuration of epoxy resin: polyamide resin curing agent: xylene diluent weight ratio of 100:30:150, after fully mixing epoxy resin, polyamide resin, xylene and stirring evenly, just prepare ring Oxygen resin spray solution.

[0038] (2) Spray film formation

[0039] After step (1) is completed, the epoxy resin spray solution prepared in step (1) is injected into the spray equipment, and then the formed ordinary Portland cement porous vegetation concrete is sprayed, and the spraying is repeated 3 times. Make the epoxy resin spray solution form a polymer film on the inner surface of the pores to isolate the seepage of alkaline substances on the inner wall of the pores, thereby reducing the alkalinity in the pores and ensuring the strength of the concrete.

Abstract

This invention relates to a reform method for alkalinity of holes for porous vegetation concrete, which confects spraying solution, carries out filming by spraying and film solidification to form a densed macromolecular film layer on the surfaces of the holes, so that the filled soil in the holes is not basified and keeps neutral for a long time, which is suitable for the growing of vegetable roots and does not influence the strength of porous concrete.

Description

technical field [0001] The invention belongs to the technical field of porous vegetation concrete, in particular to a method for transforming the pore alkalinity of ordinary portland cement porous vegetation concrete. Background technique [0002] Porous vegetation concrete is a newly emerging ecological concrete. It is a functional concrete with large porosity and high strength. After filling the pores with soil, it can adapt to the growth of plant roots and has the functions of restoring and protecting the environment. , to improve the role of ecological conditions. Its main feature is its high strength, which is used as slope protection (structural protection) for rivers, roads, railways and other structures, and has a large porosity to facilitate the growth of plant roots (vegetation greening). The pore alkalinity of the porous vegetation concrete prepared by Portland cement is too high, and the pH value reaches above 12, which is not suitable for the growth of plant ro...
