How does the quality of Cellulose Ether affect the quality of Mortar

In pre-mixed mortar, the addition of cellulose ether is minimal, but it can significantly improve the performance of wet mortar. It is a key additive affecting the construction performance of mortar. The rational selection of cellulose ether with different varieties, viscosities, particle sizes, adhesive levels, and quantities has a positive impact on the enhancement of dry powder mortar performance. Currently, many masonry and plastering mortars exhibit poor water retention properties, leading to water-cement separation after a short period of static standing. Water retention is a crucial property of methyl cellulose ether and is a performance aspect of particular concern to many dry powder mortar manufacturers in regions with higher temperatures, especially in the southern parts. Factors influencing the water retention effect of dry powder mortar include the quantity of methyl cellulose (MC) added, MC viscosity, particle fineness, and ambient temperature during usage.
