Concrete mixing foam problem.Foam is produced due to the mixing of air and the action of additives during mixing.

Key points for selecting defoamers.Emphasize the compatibility between defoamers and concrete materials, as well as their impact on the performance of concrete.

Dosage and method of administration.The reasonable dosage and time are introduced to ensure that foam can be effectively eliminated without affecting the quality of concrete.

The impact on the performance of concrete.Analyze the effects of defoamers on the strength, flowability, hardening time, and other properties of concrete.

Economic and environmental considerations.Evaluate the cost of using defoamers and their impact on the environment, and propose optimization suggestions.
