The evaluation of the performance of defoamers for concrete mainly includes indicators such as defoaming speed, foam suppression durability, compatibility, dispersibility, stability, and their impact on concrete properties (such as strength, setting time, etc.).

Select appropriate defoamers for the specific formula and usage environment of concrete. On the premise of ensuring performance, consider cost factors and choose products with high cost-effectiveness. Prioritize the use of non-toxic, harmless, and biodegradable green and environmentally friendly defoamers.

A comprehensive evaluation of the performance of defoamers is conducted through a combination of laboratory simulation experiments and practical engineering application tests. Laboratory simulation experiments mainly examine indicators such as defoaming speed and foam suppression persistence; Actual engineering application tests

pay more attention to the actual impact of defoamers on the performance of concrete.
