Thus, there seems to be agreement that methyl cellulose does not adsorb. None of these works, however, offers an alternative model which clearly can describe the mechanism behind water retention capability of MC. Accordingly, there is still a need for clarification.
Notably, the manufacturing process of MHEC powder parallels that of HPMC. However, MHEC powder necessitates the utilization of Ethylene oxide instead of Propylene oxide.
Furthermore, MHEC enhances the water resistance of cement. When MHEC is added to the mix, it forms a protective barrier that prevents water from penetrating the cement structure. This is particularly important in applications where the cement will be exposed to moisture, such as in swimming pools or basements. The improved water resistance provided by MHEC ensures that the cement remains strong and intact, even in wet conditions.
