Problems solved by technology

In order to achieve this goal, concrete mixing plants currently use high-quality sand and stone aggregates to reduce the water consumption of single concrete and increase the strength of concrete to reduce the amount of cement. The benefits brought by reducing cement are far less than the increased cost of using high-quality sand and stone

Embodiment 1

[0039] Preparation of UFD polymer copolymer:

[0040] 1) Weigh 50g of urea and 50g of deionized water, add the weighed urea and water into a 250ml three-neck bottle in turn, start stirring, adjust the stirring speed to 150rpm, after the urea is completely dissolved, weigh 10.5g of alkaline solution (alkaline solution is mixed by 4.5g ammonia water (mass fraction 28%) and 4.5g liquid caustic soda (mass fraction 40% sodium hydroxide) by mass ratio 1:1), and alkaline solution is slowly added in the there-necked flask, During this period, the stirring is not stopped, and the temperature of the water bath is raised to 50°C;

[0041] 2) Weigh 110g of 37% formaldehyde solution (the formaldehyde mass fraction in the formaldehyde solution is 37%, containing 5% methanol, and the balance is water), and when the temperature of the solution in the there-necked bottle is at 50°C, use 150ml of constant drop to dissolve The formaldehyde solution was added to the reaction system, and the drop...

Embodiment 2

[0046] First, add 5 kg of sodium tripolyphosphate into 33 kg of water and stir quickly. After it is completely dissolved, add 7 kg of sodium gluconate into it, stir and dissolve, and then add 25 kg of UFD polymer copolymer. Stir and mix, and finally add 15 kg of glycerin and 15 kg of polycarboxylic acid mother liquor into it and stir evenly to obtain a high-efficiency and energy-saving concrete synergist.

[0047]The weight percentage of the concrete synergist added in the concrete is 0.6% of the total mass of the cementitious material. Prepare relevant raw materials according to the design mix ratio of C30 concrete strength grade. Based on the mix ratio of concrete without adding synergist, add this synergist according to 0.6% of the total amount of cementitious materials. The amount of cement per kilogram is used as a comparison sample, and the test is carried out according to the "GB_T50107-2010 Concrete Strength Inspection and Evaluation Standard". The concrete test result...

Embodiment 3

[0057] First, add 3 kg of sodium tripolyphosphate into 65 kg of water and stir quickly. After it is completely dissolved, add 2 kg of sodium gluconate into it, stir and dissolve, and then add 10 kg of UFD polymer copolymer into it. Stir and mix, and finally add 10 kg of glycerin and 10 kg of polycarboxylic acid mother liquor into it and stir evenly to obtain a high-efficiency and energy-saving concrete synergist.

[0058] The weight percentage of the concrete synergist added in the concrete is 0.6% of the total mass of the cementitious material. Prepare relevant raw materials according to the design mix ratio of C30 concrete strength grade. Based on the mix ratio of concrete without adding synergist, add this synergist according to 0.6% of the total amount of cementitious materials. The amount of cement per kilogram is used as a comparison sample, and the test is carried out according to the "GB_T50107-2010 Concrete Strength Inspection and Evaluation Standard".

Abstract

The invention discloses a high-efficiency and energy-saving concrete synergistic agent and a preparation method thereof, and belongs to the concrete technical field. The concrete synergistic agent is prepared from the following raw materials in parts by weight: 10-25 parts of a UFD macromolecular copolymer, 10-15 parts of a water reducing agent mother liquor, 3-5 parts of sodium tripolyphosphate, 2-7 parts of sodium gluconate, 10-15 parts of a stabilizer, and 33-65 parts of water. The UFD macromolecular copolymer is prepared from urea, formaldehyde and sodium dodecylbenzenesulfonate. Through coordinative and promotion effects of the components, the high-efficiency and energy-saving concrete synergistic agent can increase the concrete strength grade, improve the working performance, or reduce the cement use amount under a condition of keeping the concrete working performance and the strength grade basically consistent, so as to achieve the purpose of reducing production cost of the concrete, and then achieve the purposes of saving energy, reducing consumption and reducing environmental pollution. The product production process is simple, and the product storage cycle is as long as one year.

Description

technical field [0001] The invention relates to a high-efficiency and energy-saving concrete synergist and a preparation method thereof, belonging to the technical field of concrete. Background technique [0002] In recent years, my country's economy has grown rapidly, and various constructions have made great achievements, but at the same time, it has also paid a huge price for the destruction of resources and the environment. The contradiction between the two has become increasingly acute. In order to make reasonable use of resources, prevent environmental pollution, maintain ecological balance, ensure the healthy development of human beings, and make the environment better adapt to human labor and life, as well as the survival of natural organisms, the state calls on all walks of life to protect the environment, save energy and reduce emissions . [0003] Cement is the basic industry in the traditional industry. Its high energy consumption and heavy pollution have become...
