Observe whether the surface of the cement mortar is smooth and free of bubbles and holes. Evaluate whether the strength of cement mortar meets the standard through testing methods such as compressive strength. Use tools such as density meters to test the compactness of cement mortar.

If bubble regeneration occurs during the construction process, factors such as sufficient dosage of defoamer and uniform mixing should be checked and adjusted in a timely manner. If there is unevenness on the surface of cement mortar, it can be treated by grinding, repairing, and other methods. If the test results show that the strength of

cement mortar does not meet the standard, factors such as raw material quality and mix proportion should be checked, and corresponding remedial measures should be taken.

In short, cement mortar defoamers play an important role in construction projects. By rational use and correct construction techniques, its defoaming effect can be fully utilized to improve the performance and quality of cement mortar. At the same time, close attention should be paid to the defoaming effect and problems should be solved in

a timely manner during the construction process to ensure the smooth progress and final quality of the project.
