Cement mortar, as an indispensable foundation material in construction engineering, has a direct impact on the quality and safety of buildings due to its performance. However, during the mixing, transportation, and construction of cement mortar, a large number of bubbles are often generated. If these bubbles are not treated properly, they

can lead to a decrease in material strength, uneven surfaces, and even problems such as hollowing and cracking. Therefore, cement mortar defoamers have emerged as an important tool to solve this problem.

Cement mortar defoamer is a chemical additive that can quickly eliminate and suppress the formation of bubbles in cement mortar. According to their chemical composition and performance characteristics, cement mortar defoamers can be divided into various types such as organic silicon type, polyether type, mineral oil type, and composite

type. Each type has its unique advantages and scope of application.

The use of cement mortar defoamers can not only effectively eliminate bubble problems during construction, improve the compactness and strength of cement mortar, but also improve its surface quality, reduce rework rate, and save construction costs and time. In addition, the application of defoamers also helps to improve the overall quality

and service life of buildings.
