Problems solved by technology

The production process of cement needs to consume a large amount of limestone, clay and other resources and energy such as electricity and coal. A large amount of surplus cement in concrete will also cause a lot of waste of resources and have a great impact on the environment.

Embodiment 1

[0020] A concrete glue reducer, which is composed of the following raw materials in parts by weight: 20 parts of vitamin C waste mother liquor, 0.05 parts of cocoyl glucoside, 5 parts of complexing agent, 40 parts of dispersant, 2 parts of reinforcing agent, and 60 parts of water . The vitamin C waste mother liquor is a waste liquor produced in the process of producing crude vitamin C by crystallization, and contains substances such as gulong acid, vitamin C, glucose, and organic acids.

[0021] The complexing agent is tannic acid.

[0022] The dispersant contains alpha-olefin sulfonate sodium-methacrylic acid copolymer.

[0023] The enhancer consists of ammonium thiosulfate, ammonium humate and diethanol monoisopropanolamine.

Embodiment 2

[0025] A concrete glue reducer, which is composed of the following raw materials in parts by weight: 30 parts of vitamin C waste mother liquor, 0.01 part of cocoyl glucoside, 8 parts of complexing agent, 30 parts of dispersing agent, 3 parts of reinforcing agent, and 40 parts of water . The vitamin C waste mother liquor is a waste liquor produced in the process of producing crude vitamin C by crystallization, and contains substances such as gulong acid, vitamin C, glucose, and organic acids.

[0026] The complexing agent is aminotrimethylene phosphonic acid.

[0027] The preparation method of the dispersant is as follows: add raw materials α-olefin sulfonate sodium, 2-acrylamido-2-methylpropanesulfonic acid and deionized water into the reactor, and after passing nitrogen to remove oxygen for 10 minutes, heat up to 90 °C, within 3 hours, the aqueous solution of ammonium persulfate and methacrylic acid were added dropwise, and after the reaction was continued for 2 hours, the t...

Embodiment 3

[0030] A concrete glue reducer, which is composed of the following raw materials in parts by weight: 25 parts of vitamin C waste mother liquor, 0.04 parts of cocoyl glucoside, 7 parts of complexing agent, 36 parts of dispersant, 2.4 parts of reinforcing agent, and 45 parts of water .

[0031] The complexing agent is diethylenetriaminepentamethylenephosphonic acid.

[0032] The dispersant contains α-olefin sulfonate sodium-methacrylic acid copolymer, and the preparation method is as follows: add raw materials α-olefin sulfonate sodium, 2-acrylamido-2-methylpropanesulfonic acid and After deionized water was passed through nitrogen to remove oxygen for 20 minutes, the temperature was raised to 60°C, and the ammonium persulfate aqueous solution and methacrylic acid were added dropwise within 6 hours, and the reaction was continued for 1 hour, then cooled to room temperature to obtain the dispersant. Wherein the mol ratio of methacrylic acid and α-olefin sulfonate sodium is 3:1, a...

Abstract

The invention belongs to the technical field of building materials and discloses a concrete glue reducing agent. The concrete glue reducing agent is composed of the following raw materials in parts byweight: 20-30 parts of a vitamin C waste mother solution, 0.01-0.05 part of coconut oil-base glucoside, 5-8 parts of a complexing agent, 30-40 parts of a dispersing agent, 2-3 parts of an enhancer and 40-60 parts of water. By virtue of the synergistic effect of the components, gel material particles can be well dispersed, the hydration reaction effect of a system is effectively promoted, more than 10% of cement used in the concrete can be reduced, the production cost of the concrete can be lowered, and the cracking of the concrete caused by the excessive gel material can be reduced.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a concrete glue reducer. technical background [0002] Since the 1990s, commercial concrete began to replace on-site mixing concrete on a large scale in various constructions. In order to meet the needs of high workability and strength of concrete, the amount of cementitious materials in commercial concrete is generally high, generally 350kg / m 3 above. The high amount of cementitious material in concrete makes the concrete more prone to cracking, especially in the case of low water-cement ratio, this phenomenon is more serious. In addition, research data on the degree of cement hydration in concrete at home and abroad show that under normal circumstances, about 20-30% of the cement in concrete does not participate in the hydration reaction. The production process of cement needs to consume a large amount of limestone, clay and other resources and energy ...
