How does HPMC works in masonry and plastering mortar

As the most important part of building materials commercialization, SLEO HPMC plays a vital role in masonry and plastering mortar. A good mortar should have good workability, smooth application without sticking, sufficient operating time, and easy leveling; in today’s mechanized construction, the mortar should also have good pumpability to avoid segregation and blockage. The hardened mortar should have excellent strength properties and surface appearance, suitable compressive strength, good durability, no hollowing and cracking.
The water retention performance of Hydroxypropyl methyl cellulose promotes better hydration of the cement materials. In large-area construction, it can greatly reduce the early drying and cracking probability of the mortar and improve the bonding strength; its thickening ability can be Improve the wetting ability of the wet mortar to the base surface; HPMC stabilizes the wet mortar, reduces or avoids delamination and bleeding, improve the lubricity and rheology of the mortar, reduce resistance, thereby increasing pumpability and reducing intensity of labor. The modified cellulose ether provides indispensable anti-sagging performance when applying thick mortar, which can reduce construction time and reduce waste.
