Uses
Concrete: SNF water reducing agent can improve the strength and durability of concrete by increasing its fluidity and reducing its viscosity, reducing the amount of cement used. In addition, SNF water reducing agent can also reduce concrete surface cracks and shrinkage.
Cement products: SNF water reducing agent can be used to manufacture cement mortar, blocks, pipes, floor tiles, and other cement products to improve their fluidity, reduce the amount of cement used, improve strength, and reduce shrinkage.
Mortar: SNF water reducing agent can be used to manufacture mortar to improve its fluidity, increase viscosity, increase setting time, and reduce shrinkage.
Other fields: SNF water reducer can also be used in the manufacturing of casting, pulp, asphalt, and other fields. In these fields, SNF water reducing agents can be used as adhesives, dispersants, and thickeners to improve the performance of materials and processing processes.
