Cement Based Tile Adhesive Mortars Additives Redispersible Polymer Powder Vae/RdpMay 26th 2023
In cement mortar, HPMC is commonly used as a thickening agent and water retention agent. The addition of HPMC to cement mortar can improve its workability, enhance its bonding strength, and reduce the occurrence of shrinkage cracks.
When HPMC is added to cement mortar, it forms a film on the surface of cement particles, which reduces the water absorption rate and improves water retention. This, in turn, improves the consistency and workability of the mortar, making it easier to apply and spread. HPMC also acts as a binder, helping to improve the adhesion between the mortar and the surface it is applied to.
In addition, HPMC can also help to prevent the segregation of the mortar during application, which can lead to uneven drying and cracking. The use of HPMC in cement mortar can also improve the strength of the mortar and reduce its susceptibility to freeze-thaw damage.
Overall, the addition of HPMC to cement mortar can improve its performance and durability, making it a valuable additive in the construction industry.
