This article introduces the influence of acrylic acid dosage and feeding method on the mother liquor. Any product will gradually become homogeneous in market competition, and buyers will also have higher requirements for the product. The production process of water reducing mother liquor is similar nationwide, and even with different catalysts, mother liquor with a similarity of 90% or even 95% can be obtained. Among the two synthesis methods mentioned in this article, adding 8% A material solution at once is the mother liquor synthesized by the two processes. There is no difference in water reduction rate, but there is a significant difference in concrete compatibility. As the amount of pre added acrylic acid increases, the water reduction rate can be improved, but the negative effects are even greater. In addition, the author found in the experiment that another catalyst process is more suitable for the operation mode of pre adding A material. There is not much room for modification in the existing mother liquor synthesis process, but optimization can better adapt to local concrete materials.

The main issue studied in this article is the hydration process of cement, including the induction period, acceleration period, attenuation period, and stabilization period.

This article introduces the experimental process and results of synthesizing slow-release polycarboxylate mother liquor at room temperature, as well as the application of this mother liquor in improving the problem of concrete slump loss. By chemically repairing the water reducing mother liquor and introducing carboxylic acid derivatives, the carboxylate ions in the molecules are initially protected. By utilizing their hydrolysis reaction during the concrete mixing process, the anchoring carboxylate ions are gradually released and dispersed, achieving the effect of slowly dispersing cement particles. The application of this mother liquor effectively improves the sensitivity of polycarboxylate admixtures to concrete raw materials and enhances their adaptability to concrete. However, due to the low initial water reduction rate, additional costs are often required in applications.

This article mainly introduces the synthesis operation of concrete admixtures, covering equipment, instruments, raw materials, operation steps, and other content. The article first introduces the equipment required for synthesizing polycarboxylate admixtures, including peristaltic pumps, mixers, four necked flasks, etc., and provides a detailed explanation of the purpose and selection of each equipment. The article then explores the raw materials used in the synthesis process, including water, macromers, acrylic acid, vitamin C, hydrogen peroxide, mercaptoacetic acid, etc., and provides a detailed explanation of the specifications and sources of each raw material. At the end of the article, a detailed record of the process of a synthesis experiment was provided, including the selection of equipment and instruments, weighing and preparation of raw materials, synthesis steps, and performance testing of the mother liquor. The performance of the synthesized mother liquor is comparable to most products on the market. The article also explores the impact of different raw materials or processes on the application effect, which is worth studying.

The fluidity of the slurry has good reference significance for the factory inspection of additives and the comparison of the mother liquor water reduction rate

This article discusses how to practice the operation of mixing ten liters of concrete in a mixer, determining the state of concrete discharge, and adjusting methods when concrete problems occur.

This article introduces the types of admixtures and the raw materials required for the compounding of admixtures.

Concrete admixtures are materials that are added to concrete during the mixing process to enhance the properties of concrete. They have been used since ancient times, but the development of modern concrete admixtures began in the mid-19th century. Here is a brief history of the development of concrete admixtures:

Woxin, one of the major manufacturers of concrete admixtures & machinery in China, was established in Xuzhou of China. It is specialized in concrete admixtures & machinery's research, manufacturing, and distribution. The company has an area of more than 134,000m2 and about 200 employees, among them 25% engineers and knowledge-workers.
