Role hydroxyethyl methyl cellulose in cement

Certain cellulose content of the water held there is sufficient time to promote continued hydration of cement to improve adhesion of the mortar to the substrate in the mortar. Water retention capacity of the mortar to a large extent influenced by the time of dissolution, thin fast dissolving cellulose, water retention properties it on sooner. For the mechanization of construction, due to time constraints, be sure to select the fine cellulose powder. For manual plastering, fine powder on it. Cellulose solubility in water and temperatures are dependent on the degree of etherification, outside temperatures, reduce water retention; the higher the degree of etherification, cellulose ethers better water retention.
