Since slag powder differs greatly from fly ash and silica fume in the chemical composition and particle morphology, it exhibits different behaviors and plays different roles in cement concrete.   Water Demand It is generally believed that slag powder has little effect on the water demand. In the chemical composition and mineral composition, slag powder.. read more →

Water retention is an important property of cellulose ether. The factors affecting the water retention effects of dry-mixed mortar include the addition amount, viscosity, fineness, the temperature of use environment of mortar.   Effects of the Addition Amount of Cellulose Ether on Water Retention When the addition amount of cellulose ether is within the range.. read more →

The cellulose ether and cellulose derivative are a large category of additives, usually powdery (or granular), and a few slurry (the suspensions formed when cellulose esters do not dissolve). Despite the competition against synthetic rheological modifiers, the cellulose derivative is still the main force of “thickening agents”, and mainly used for the production of various.. read more →

Cellulose ether is a major additive in the dry-mix mortar. Although the addition amount is very low, it can significantly improve the performance of mortar. It can improve the consistency, working performance, bonding properties and water retention properties of mortar, and plays a very important role in the field of dry-mix mortar. Its main features.. read more →

According to the ionization performance of substituents, cellulose ethers can also be divided into ionic and non-ionic types. The ionic type mainly includes carboxymethyl cellulose salt (CMC), while the non-ionic type includes methyl cellulose, methyl hydroxyethyl cellulose ether (MHEC), methyl hydroxypropyl cellulose ether (MHPC), and hydroxyethyl cellulose ether. Since the ionic cellulose (carboxymethyl cellulose salt).. read more →

Cellulose ether is the powdered cellulose ether generated with wood fiber or refined short cotton fiber as the main raw materials, after chemical treatment and by the reaction of etherifying agents such as chlorinated ethylene, chlorinated propylene and oxidized ethylene. The production process of cellulose ether is complex. It starts with the extraction of cellulose.. read more →

How to choose cellulose ethers? In the dry-mixed mortar, the cellulose ether plays a role in such aspects as water retention, thickening and improving construction performance. Good water retention can avoid the sugaring, dusting and strength decrease of mortar resulting from water shortage and incomplete cement hydration; the thickening effect makes the structural strength of.. read more →
