1. Enhanced Water Retention
One of the main functions of HPMC is to enhance the water retention of mortar. It can retain more free water in the mortar, giving the cementitious material more time to undergo hydration reaction, thereby improving the overall performance of the mortar. The water retention of KimaCell®HPMC is essential to prevent the mortar from drying too quickly and ensure that it has sufficient operating time during construction.
2. Improved Cracking Resistance
By improving the water retention of mortar, HPMC can also effectively inhibit the formation of mortar cracks. Mortar with good water retention can reduce the rapid evaporation of water, thereby reducing the volume shrinkage caused by water loss, and thus reducing the occurrence of cracks.
3. Improved Construction Performance
The water retention of HPMC also directly affects the construction performance of mortar. Mortar with good water retention exhibits better wet bond strength and anti-sagging performance during construction, making construction smoother and reducing construction difficulty.
4. Seasonal Effects
The water retention of HPMC may vary in different seasons. For example, in hot seasons, the water retention effect of HPMC may be challenged, so it is necessary to select high-quality HPMC to ensure the water retention performance of mortar under high temperature conditions.
5. Effect of fineness and viscosity
The fineness and viscosity of HPMC also have a significant effect on its water retention performance. Generally speaking, the finer the fineness and the higher the viscosity of HPMC, the better its water retention performance. However, too high viscosity may affect the solubility and construction performance of mortar, so it is necessary to select the appropriate HPMC product according to the specific application.
Hydroxypropyl methylcellulose (HPMC) is extremely important for the water retention of mortar. It can not only improve the water retention capacity of mortar and improve construction performance, but also effectively inhibit the formation of cracks. When selecting KimaCell®HPMC products, its fineness, viscosity and water retention performance in different seasons should be considered to ensure the best performance of mortar.
