Will the water retention performance of aquasorb in mortar change after long-term storage?

As a highly efficient water-retaining agent, aquasorb is widely used in premixed mortar. Its excellent water absorption capacity helps the mortar retain the necessary moisture during construction and hardening, thereby optimizing the working performance and physical properties of the mortar.
First of all, it should be made clear that the water retention performance of aquasorb is not static, but is affected by many factors. During storage, aquasorb may be affected by environmental factors such as temperature, humidity, and light, resulting in subtle changes in its chemical structure and physical properties. These changes may directly affect the water absorption and water retention of the resin.
Specifically, if the storage environment temperature is too high, aquasorb may undergo thermal degradation, resulting in the breaking of chemical bonds inside the resin, thereby reducing its water absorption capacity. Similarly, an environment with excessive humidity may also cause the resin to absorb water saturated, and then gradually lose its water retention performance during storage. In addition, long-term light exposure may also cause photo-oxidative degradation of the resin, further affecting its performance.
In mortar systems, long-term storage of aquasorb may also be affected by factors such as mortar composition, pH value, and ionic strength. For example, certain chemical components in the mortar may react with the resin, causing changes in the resin structure, thereby affecting its water retention performance. At the same time, the pH value and ionic strength of the mortar may also affect the water absorption rate and water absorption saturation of the resin.
In order to evaluate the effect of long-term storage on the water retention performance of aquasorb in mortar, regular performance tests are recommended. These tests can include water absorption rate tests, water absorption saturation tests, and mortar working performance tests. By comparing the performance changes of the resin before and after storage, the degree of influence of storage time on the water retention performance of the resin can be intuitively understood.
In summary, the water retention performance of aquasorb in mortar may indeed change after long-term storage. Therefore, in practical applications, we need to pay close attention to the impact of storage conditions on resin performance and take corresponding measures to ensure that the water retention performance of the resin remains stable during storage. At the same time, regular performance testing is also essential to detect and solve problems in a timely manner.
