Within hydroxyethyl methyl cellulose, the inclusion of methoxy groups serves to lower the surface energy of aqueous solutions containing this compound.  Consequently, hydroxyethyl methyl cellulose imparts an air-entraining effect when used in cement mortar.  This effect introduces controlled air bubbles into the mortar, a phenomenon akin to the “ball effect,” which in turn enhances the workability of the mortar during construction.  Simultaneously, the introduction of these air bubbles can boost the mortar’s yield.  However, it’s imperative to exercise restraint in managing the degree of air entrainment, as an excessive amount can adversely impact mortar strength.

Notably, hydroxyethyl methyl cellulose possesses the capability to prolong the setting process of cement.  While this delay extends the setting and hardening of cement, consequently elongating the open time of mortar, it may not be ideal for mortar applications in colder regions.

As a high-molecular-weight polymer substance, hydroxyethyl methylcellulose, when added to cement systems while preserving adequate moisture in the mixture, significantly enhances bonding performance with the substrate.
