- The development of HEMC technology is driven by a need to address growing concerns over climate change and the depletion of fossil fuels. By harnessing clean energy from renewable sources, HEMCs significantly reduce carbon emissions and dependency on non-renewable resources. Additionally, their modular design allows for scalability, making them ideal for both small communities looking to go off-grid and large cities aiming to enhance their energy security and sustainability.
- Superplasticizers are admixtures that significantly increase the flowability of concrete without increasing its water content. By enhancing the dispersion of cement particles, superplasticizers allow for easier placement and compaction of concrete, even in congested reinforcement areas. They are particularly useful in slipform paving, where rapid setting times are required, and in precast elements, where high early strength is essential.

- Chemically modified HPMC, through processes such as esterification, etherification, or crosslinking, enhances its adhesive properties significantly. These modifications introduce new functional groups that not only improve adhesion strength but also offer better control over the bonding characteristics. For instance, esterification introduces hydrophobic moieties, enabling enhanced adhesion to hydrophobic surfaces, while crosslinking results in increased mechanical stability and durability.

The factors that affect the water retention of mortar also include cellulose ether viscosity, addition amount, particle fineness and use temperature.
It is well known that the higher the viscosity, the better the water retention effect. However, the increase of viscosity means the increase of the added amount, but the higher the viscosity, the higher the molecular weight of HPMC, and the corresponding decrease in its solubility, which has a negative impact on the strength and construction performance of mortar. The higher the viscosity, the more obvious the thickening effect of mortar, but it is not proportional. The higher the viscosity, the stickier the wet mortar will be. During construction, the stickiness of the scraper and the substrate is high. But it is not helpful to increase the structural strength of the wet mortar itself. Therefore, it is not recommended to use this water retention method, which increases the cost and does not have a good effect.
The larger the amount of cellulose ether added to the mortar, the better the water retention performance, the higher the viscosity, and the better the water retention performance.
