Problems solved by technology

[0005] After the existing technology is used in concrete, although it can reduce the amount of cement used and maintain the strength of the concrete, the existing technology contains a large amount of formaldehyde, which will cause The release of formaldehyde not only easily leads to the deterioration of the effect of the existing technology, but also easily causes environmental pollution, resulting in relatively large limitations in the use and promotion of the existing technology

Embodiment 1

[0060] Embodiment 1: A concrete glue reducer, the components included and their corresponding qualities are shown in Table 1, and are prepared through the following steps:

[0061] Step 1: Mix the organic alcohol amine compound, thickener, and polyethylene glycol ether uniformly at a temperature of 45°C to obtain a mixture A;

[0062] Step 2, adding anhydrous sodium sulfate, sodium thiosulfate and sodium gluconate into water, fully dissolving, and mixing uniformly to obtain mixture A1;

[0063] Step 3: heat-insulate the mixture A obtained in step 1 at a temperature of 25° C., mix the mixture A1 obtained in step 2 with mixture A uniformly, cool to room temperature, and discharge to obtain a concrete adhesive reducer.

[0064] Wherein, the molecular weight of polyethylene glycol ether is 1600.

Embodiment 2-9

[0065] Embodiment 2-9: A concrete reducer, the difference from Embodiment 1 is that the components included and their corresponding qualities are shown in Table 1.

[0066] Table 1. Components of Examples 1-9 and their quality

[0067]

[0068] Wherein, in the nano-microcrystalline cellulose colloid in Example 2, the content of nano-microcrystalline cellulose is 0.01%; in the nano-microcrystalline cellulose colloid in Example 3, the content of nano-microcrystalline cellulose is 0.02%; In the nano-microcrystalline cellulose colloid in embodiment 4, the content of nano-microcrystalline cellulose is 0.03%,; In the nano-microcrystalline cellulose colloid in embodiment 5, the content of nano-microcrystalline cellulose is 0.04%; Implementation In the nano-microcrystalline cellulose colloid in example 6, the content of nano-microcrystalline cellulose is 0.05%; The content is 0.02%.

Embodiment 10

[0069] Embodiment 10: A concrete glue reducer, the difference from Embodiment 1 is that the molecular weight of polyethylene glycol ether is 2200.

Abstract

The invention discloses a concrete adhesive reducer and its preparation process and application method. Wherein, the concrete glue reducer includes the following components in parts by weight: 35-50 parts of organic alcohol amine compounds; 1-5 parts of anhydrous sodium sulfate; 2-10 parts of sodium thiosulfate; 0.1-3 parts of sodium gluconate 1-5 parts of thickener; 3-10 parts of polyethylene glycol ether; 55-70 parts of water; organic alcohol amine compounds include at least one of triethanolamine and triisopropanolamine; thickener includes yellow At least one of raw gum, polyacrylamide, and hydroxyethyl methylcellulose ether. Concrete reducer can be used in the mixing process of concrete. It has no pungent smell and has the advantages of environmental protection. When added to concrete, it can reduce the amount of cement used and improve the strength of concrete.

Description

technical field [0001] The invention relates to the technical field of concrete additives, more specifically, it relates to a concrete glue reducer and its preparation process and application method. Background technique [0002] With the advancement of concrete high-performance application technology, the demand for improving concrete performance while reducing concrete production costs and ensuring concrete strength has further increased. [0003] Concrete reducer is an emerging functional concrete admixture in the construction market, which can promote the hydration reaction of cement in concrete more fully, save the amount of cement or other gel materials in concrete in actual engineering construction, and improve the quality of concrete. Excellent workability, anti-bleeding, no segregation and easy pumping. [0004] The Chinese patent with application publication number CN105174774A and application publication date of December 23, 2015 discloses a concrete glue reducer...
