Embodiment 1

[0035] Special admixture for slope protection planting concrete and preparation method thereof, the preparation steps are as follows:

[0036] (1) Mix industrial acetic acid and water at a ratio of 1:1 to obtain an acetic acid solution, add cigarette ash and water at a ratio of 1:8, shake evenly for 1 hour, and take the supernatant to obtain incense Tobacco ash solution, after mixing the acetic acid solution and the cigarette ash solution respectively to obtain the insecticidal alkali-reducing agent, take 5 parts;

[0037] (2) Mix the washed and crushed okra with water at a ratio of 1:10, stir the mixture well for 30 minutes, let it stand for 2 hours, and then filter and collect the colorless viscous extract with a 150 μm sieve. The obtained okra extract is fully stirred to obtain the okra extract; 40 parts of the okra extract, 3 parts of polyacrylamide (molecular weight is 8 million), 30 parts of disodium dihydrogen pyrophosphate, and 27 parts of water are mixed Get the wate...

Embodiment 2

[0041](1) Mix industrial acetic acid and water at a ratio of 1:1.5 to obtain an acetic acid solution, add cigarette ash and water at a ratio of 1:8, shake evenly for 2 hours, and take the supernatant to obtain incense Tobacco ash solution, after mixing the acetic acid solution and the cigarette ash solution respectively to obtain the insecticide and alkali-reducing agent, take 7 parts;

[0042] (2) Mix the washed and crushed okra with water at a ratio of 1:20, stir the mixture well for 30 minutes, let it stand for 2 hours, and then filter and collect the colorless viscous extract with a 150 μm sieve. The obtained okra extract is fully stirred to obtain okra extract; 45 parts of okra extract, 5 parts of polyacrylamide (molecular weight is 6 million), 25 parts of disodium dihydrogen pyrophosphate, and 25 parts of water are mixed. Get the water retaining agent evenly, take 20 parts;

[0043] (3) Wash the straw with water and cut it into small pieces, dry it in an oven at 80°C fo...

Embodiment 3

[0046] (1) Mix and stir industrial acetic acid and water at a ratio of 1:1.5 to obtain an acetic acid solution, add cigarette ash and water at a ratio of 1:10, shake evenly for 2 hours, and take the supernatant to obtain incense Tobacco ash solution, after mixing the acetic acid solution and the cigarette ash solution respectively to obtain the insecticidal alkali-reducing agent, take 3 parts;

[0047] (2) Mix the washed and crushed okra with water at a ratio of 1:20, stir the mixture well for 30 minutes, let it stand for 2 hours, and then filter and collect the colorless viscous extract with a 150 μm sieve. The obtained okra extract is fully stirred to obtain okra extract; 43 parts of okra extract, 4 parts of polyacrylamide (molecular weight is 6 million), 26 parts of disodium dihydrogen pyrophosphate, and 27 parts of water are mixed Get the water retaining agent evenly, take 15 parts;

Abstract

The invention discloses a special additive for slope-protection plant-growing concrete and a preparation method thereof. The special additive is prepared from the raw materials: 20-30 parts of water reducing agent, 3-7 parts of insecticide alkalinity reducing agent, 15-20 parts of water retaining agent, 1-5 parts of thickener and 40-60 parts of water. The components are added into a compounding tank and stirred to be uniform, and the special additive is prepared. The special additive applicable to the slope-protection plant-growing concrete solves the problems including that the cement slurryrheolytic capability and the interface binding force in the slope-protection plant-growing concrete are poor, the pH value is slightly high, and the plants are short of water and have massive pests. The plant-growing concrete applying the additive cannot only meet the normal growing requirements of herbal plants, but also can meet the growing demands of vine and woody plants, the selective plant species of the plant-growing concrete are further enriched, and the meaning of ecological greening of the plant-growing concrete is achieved to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of concrete admixtures in building materials, and in particular relates to a special admixture for slope protection planting concrete and a preparation method thereof. Background technique [0002] Slope protection is divided into traditional slope protection and planting concrete slope protection, and traditional slope protection is mainly divided into vegetation slope protection, hole type slope protection and concrete slope protection. Although traditional slope protection has been widely used, there are still many defects: concrete slope protection has a rough surface, lacks toughness and high alkalinity, lacks vigor in the sense, and cannot be used for vegetation cultivation; The excavation ability is poor; the vegetation slope protection has obvious peeling and degradation. [0003] The current plant-based concrete lacks a strict definition, and it is a kind of ecological concrete. According to the c...
