How do ready-mixed mortar additives improve the performance of mortar

In the ready-mixed mortar, cellulose ether is the main additive, and the addition amount is very low, but it can improve the performance of the wet mortar and affect the construction performance of the mortar. Reasonable selection of cellulose ethers of different varieties, different viscosities, different particle sizes, different viscosities and added amounts will have a positive impact on the improvement of the performance of dry mortar.
In the production of building materials, especially dry mortar, cellulose ether plays an irreplaceable role, especially in the production of special mortar (modified mortar), it is an indispensable and important part. Cellulose ether has the functions of water retention, thickening, delaying cement hydration power, and improving construction performance. The good water retention capacity makes the cement hydration more complete, can improve the wet tackiness of the wet mortar, increase the bonding strength of the mortar, and the time can be adjusted. Therefore, cellulose ether is widely used as an important additive in ready-mixed mortar.
Redispersible latex powder is a powdered thermoplastic resin produced by spray drying and subsequent processing of polymer emulsions. Redispersible latex powder in wet mortar can improve construction performance, improve fluidity, increase thixotropy and sag resistance, increase cohesion, extend open time, enhance water retention, etc., and improve the tensile strength of the mortar after curing. Tensile strength, enhanced bending strength, reduced elastic modulus, improved deformability, increased material density, increased wear resistance, increased cohesive strength, decreased carbonization depth, decreased material water absorption, and made the material have better hydrophobicity, etc. effect.
