Cellulose Ethers HPMC in Ready - Mixed Mortar
HPMC | Cellulose Ethers | Ready - Mixed Mortar
In ready-mixed mortar, cellulose ether HPMC plays a role in water retention, thickening, delaying cement hydration power, and improving construction performance. Good water retention capacity makes cement hydration more complete, can improve the wet viscosity of wet mortar, improve the bonding strength of mortar, and adjust the time. Adding cellulose ether to mechanical spraying mortar can improve the spraying or pumping performance of mortar, as well as the structural strength. Therefore, cellulose ether HPMC is being widely used as an important additive in ready-mixed mortar.
With the increase of cellulose ether amount, the setting time of mortar increased significantly. There is a good non-linear correlation between the initial setting time of mortar and the amount of cellulose ether hpmc, and a good linear correlation between the final setting time and the amount of cellulose ether. We can control the operable time of the mortar by changing the amount of cellulose ethers hpmc.
