Concrete flocculant. What flocculants are commonly used in the production of underwater concrete in commercial mixing stations? Tell me what you know. Thank you.

The flocculant used for concrete and the flocculant used for water treatment have the same name, but they are actually different substances. Flocculants used in mixing stations are usually composed of high molecular polymers and compatible water reducing agents. There are polypropylene, cellulose ether and polysaccharide in China. Generally, the unit price is below 12000 yuan/ton or the content exceeds 3%. The biggest problem is that the slump loss is too fast, the low-temperature strength is not well developed, the land-water strength is relatively low, and the absolute strength of concrete is also low. The phenomenon of "bottom" is serious, which is not suitable for commercial concrete or pumping technology and has been gradually eliminated. The other two types of flocculants do not have these problems, but the cost will be more expensive. From the application and research articles published in China, UWB-II concrete flocculant produced by China Petroleum Engineering Technology Research Institute has good performance and many engineering cases, which is more suitable for commercial mixing stations or pumping technology and can be used as a reference.
