Hydroxypropyl methylcellulose plays an important role in cement mortar.

I. Water retention

After adding hydroxypropyl methylcellulose to cement mortar, it can effectively lock in moisture and prevent excessive evaporation of moisture. This enables cement to fully undergo hydration reaction and ensures that cement mortar maintains suitable construction performance for a long time. Whether constructed in hot and dry weather or in a well-ventilated environment, it can greatly reduce problems such as cracking and hollowing caused by rapid water loss.

II. Thickening property

Hydroxypropyl methylcellulose can increase the viscosity of cement mortar. This makes the mortar more easily adhere to the base such as walls and floors during the smearing process, reduces sagging phenomenon, and improves construction efficiency and quality. At the same time, the thickened mortar can better fill the gaps in the base layer and make the surface after construction more flat and smooth.

III. Improve bond strength

It can enhance the bonding force between cement mortar and the base layer. Through interaction with cement particles and the surface of the base layer, a tighter bond is formed, thereby preventing the mortar layer from peeling and falling off. This is crucial for ensuring the structural stability and durability of buildings.

IV. Improve construction performance

Hydroxypropyl methylcellulose can also improve the workability of cement mortar, making it easier to stir and smear. Workers will feel more relaxed and labor-saving during the construction process and improve construction efficiency. In addition, it can also reduce the segregation phenomenon of mortar during stirring and transportation to ensure the uniformity of mortar.
