What is Concrete admixture?
Concrete admixtures (English: Concrete Admixtures) are referred to as admixtures for short, which refer to the substances added to improve the performance of concrete before or during mixing. The content of concrete admixture is generally not more than 5% of the cement quality.

Concrete admixtures refer to substances added to improve and adjust the performance of concrete. More and more attention has been paid to the application of concrete admixtures in engineering. The addition of admixtures plays a certain role in improving the performance of concrete, but the selection, addition method, and adaptability of admixtures will seriously affect its development.
Applications of Concrete admixtures
Concrete admixtures play an important role in practical use. Not only that, but the technology of applying admixtures has also made rapid development.
1. The role of air-entraining agent. Enhance the contact area between liquid and outside air, and improve the workability of concrete.
2. The role of the retarder. Prolong the normal hydration and hardening time of cement and reduce the early hydration heat generated by cement.
3. The role of early strength agent. Shorten the setting time of cement quickly.
4. The function of compound expansion agent. Improve the early strength of concrete and increase the internal volume of cement.
5, the role of water-reducing agents. The effect of reducing cement consumption.

Manufacturing method of concrete admixture
- First, condensation and then copolymerization
The so-called first condensation and then polymerization means that aliphatic carboxylic acid monomers, usually acrylic acid or methacrylic acid monomers, are condensed with polyethylene glycol ether, and active double bonds are introduced into polyether to condense into active macromonomers with molecular weight between 200 and 3,000, and then the macromonomers are copolymerized with various carboxylic acid monomers.
- First, copolymerize and then condense
The first step of copolymerization, followed by condensation, refers to the first step of homopolymerizing or copolymerizing one or more carboxylic acid monomers in solution to form a high polymer with molecular weight ranging from several thousand to tens of thousands. The second step involves a condensation reaction between the high polymer and monomethoxypolyethylene glycol ether under the action of the catalyst, and the polyether side chain is introduced into the main chain of the high polymer.
