1. After the cellulose ether in the mortar is dissolved in water, the surface activity ensures the effective and uniform distribution of the cementitious material in the system. As a protective colloid, the cellulose ether "wraps" the solid particles and forms a layer of lubricating film on its outer surface, which makes the mortar system more stable, and also improves the fluidity of the mortar in the mixing process and the smoothness of the construction.
2. Due to the molecular structure characteristics of cellulose ether solution, the water in the mortar is not easy to lose, and gradually released over a long period of time, giving the mortar good water retention and workability.
