Cellulose ether has a high price and needs to find a balance between performance improvement and cost control. It is recommended to choose well-known domestic brands for higher cost-effectiveness. In practical applications, it is necessary to optimize the addition amount through experiments, balance cost and performance, and pay attention to selecting appropriate cellulose types and construction processes. With the promotion of green buildings and pre mixed mortar, the application prospects of cellulose ether are becoming increasingly broad.

Shrinkage inhibition: Flax cellulose fibers can significantly inhibit self shrinkage, and short fibers (0.5mm) have better effects than long fibers (5mm). Crack blocking: The mesh structure of cellulose fibers enhances the toughness of mortar and reduces the propagation of microcracks. Practical significance: Improved crack resistance and extended mortar life, suitable for exterior wall plastering and insulation mortar.

Cost control: Cellulose ether has a high price (about 20-50 yuan/kg), and excessive addition will increase costs. Industry research shows that cellulose ether accounts for over 40% of the cost of dry mixed mortar materials, and a balance between performance and economy is needed. Upper limit of dosage: Studies have shown that when the amount of cellulose added exceeds 0.5%, the improvement in water retention is limited and may reduce the strength of the mortar. Therefore, excessive addition is not recommended.

Cement based materials (such as mortar and concrete) are prone to problems such as insufficient strength and cracking due to rapid loss of moisture during the hydration process.
