The mechanism by which concrete shrinkage cracking occurs is as follows. In setting and hardening of concrete, the volume will change and the set cement will generate heat of hydration. Due to different rates of temperature increases and decreases on the surface or in the inner part of components, shrinkage deformation of concrete will be.. read more →

Cellulose ethers influence on water retention and consistency in cement-based mortars 1. Introduction Factory-made mortars have been mostly implemented as masonry renderings, fixing tiles, self-levelling floors and so on. When mortar is applied on substrate, water may be absorbed by the substrate. This phenomenon can induce insufficient hydration of cement, and thus decrease mechanical properties.. read more →

Application of Cellulose Ether in Dry Mortar   In the dry mortar, cellulose ether plays the role of retaining water, thickening and improving construction performance. Good water retention performance ensures that the mortar will not be sanded, dusting and strength due to lack of water, cement hydration incompleted, thickening effect makes the structural strength of.. read more →

Viscosity of Cellulose Ether   Viscosity is an important parameter of Hydroxypropyl Methylcellulose performance. Different Hydroxypropyl Methylcellulose manufacturers use different methods and instruments to test the viscosity of Hydroxypropyl Methylcellulose currently. The main methods are Haake Rotovisko, Hoppler, Ubbelohde and Brookfield. For the same product, the viscosity has big differences by different test method, some.. read more →

Water Retention of Cellulose Ether   Water retention is an important property of cellulose ether, and it is also a concern of many domestic drymix mortar manufacturers, especially those in the south area with high temperature. Factors that affects the water retention effect of the mortar include the amount of Hydroxypropyl Methylcellulose, the viscosity of.. read more →
