The Role of Cellulose in Enhancing Cement Properties and Performance
Enhanced adhesion to the masonry surface, increased water retention, and thus mortar strength.
Improved lubricity and plasticity for better workability and easier, time-saving, and cost-efficient application of mortars made with guaranteed cellulose ethers.
A special high water retention version is available for highly absorbent bricks.

In general, the gel temperature of HPMC is around 60℃-75℃ depending on its group content and different production technique. Due to the characteristics of MHEC group, it has a higher gel temperature, usually > 80℃. Therefore its stability under high temperature is better that HPMC. In practical construction, in the hot construction environment in summer, the water holding capacity of MHEC with the same viscosity and dosage is better than that of HPMC. Especially in the Southeast Asian countries and India, mortar will sometimes be constructed at high temperature. Cellulose ether with low gel temperature will lose its thickening and water retention at high temperature, thereby accelerating the hardening of mortar, and affects the construction.
