CMC-sodium carboxymethyl cellulose has many applications in building materials, mainly including the following aspects:

Cement reinforcement: CMC can be used as a cement reinforcement to improve the strength and impermeability of cement. The cement mortar mixed with CMC can significantly increase its compressive, tensile and flexural strength, effectively reduce bleeding and shrinkage, improve the adhesion of old and new mortar, reduce bleeding rate, and improve frost resistance.

Paint thickener: Adding CMC to the paint can increase the viscosity and suspension of the paint, prevent sedimentation, improve the rheological properties, improve the water resistance and weather resistance of the paint film, and at the same time increase the gloss and elasticity of the paint.

Strengthening agent for gypsum products: CMC can be used as a strengthening agent for gypsum products to improve the strength and flexural strength of products, improve the brittleness of products, and improve water resistance.

Binder in ceramic production: CMC can be used as a binder in ceramic production to improve the plasticity and strength of the green body, improve the drying performance of the green body, prevent cracking, and improve product quality.

Glass reinforcement: CMC can be used as a glass reinforcement to improve the strength and impact resistance of glass.
