In construction, cement mortar is widely used as a basic material in various aspects such as wall masonry, ground leveling, plastering, etc. However, during its preparation and construction process, a large number of bubbles are often generated, which not only affect the appearance quality of the material, but may also reduce its strength and

durability. Therefore, cement mortar defoamers have emerged as a key additive to solve this problem.

The defoamer for cement mortar mainly reduces surface tension, destroys the stable film layer of bubbles, causes the bubbles to quickly rupture and release the enclosed gas, thereby achieving the goal of eliminating bubbles. At the same time, excellent defoamers should also have good anti foaming performance to prevent the recurrence of

new bubbles.

The use of cement mortar defoamers can significantly improve construction efficiency, improve project quality, reduce problems such as cracks and hollowing caused by bubbles, and extend the service life of buildings.

An appropriate amount of defoamer can improve the fluidity and pumpability of cement mortar, making construction smoother. However, excessive use may cause the mortar to be too thin, affecting the construction strength. Defoamers can effectively reduce the porosity in mortar, improve compactness, and enhance its compressive and

flexural strength. However, it should be noted that certain defoamers may undergo chemical reactions with cement, affecting the long-term mechanical properties of the material. By eliminating bubbles, defoamers help improve the durability indicators such as impermeability and freeze-thaw cycle resistance of cement mortar, reducing the risk

of water erosion and freeze-thaw damage.
