Advantages of HPMC in Construction Materials
December 26th 2024
Hydroxypropyl methyl cellulose HPMC is mainly used as a high-efficiency water-retaining agent in building dry-mixed mortar. It can make the mortar have good plasticity and flexibility and improve the bond strength of the mortar.
At the same time, HPMC can reduce the bleeding rate and stratification degree of mortar, improve the cohesion and flow resistance of mortar, and improve the mortar’s construction performance.
The suitable content of HPMC in building dry-mixed mortar is 0.1%-0.3%.
In addition, HPMC can effectively restrain the formation of mortar plastic cracks and reduce the mortar plastic cracking index.
