  • The Role of Water Reducing Admixtures in Concrete Construction

    As a modified cellulose, HPMC has excellent thickening, bonding and water retention properties. When added to mortar, it can significantly improve the operability of the mortar, extend the construction time, reduce vertical slippage, and provide better working conditions for construction workers. In addition, the use of HPMC can effectively reduce the evaporation of water during the construction process of the mortar and improve the strength and durability of the mortar.

    The different grades of PVA exhibit varying levels of solubility. Fully hydrolyzed PVA, for instance, is more soluble in water compared to partially hydrolyzed PVA. This difference is crucial when selecting the appropriate grade for a specific application. Industries often utilize lower degrees of hydrolysis for applications requiring a less viscous solution, while higher degrees are preferred when a stronger film-forming property is required.
