GRC

Cement: The cements commonly used in GRC boards include fast-hard sulphoaluminate cement, low-salt sulphoaluminate cement, general portland cement, and white portland cement.

Fibers: The fibers used in the GRC data must be alkali-resistant glass fibers. The types include alkali-resistant glass fiber rovings, alkali-resistant glass fiber chopped yarns, and alkali-resistant glass fiber meshes. European and American countries require glass used in GRC.

The content of zirconia is not less than 16.5%. China requires that the content of zirconia be not less than 16.5% when using ordinary portland cement.

Polymer: A generally added polymer is acrylic, ie an acrylate copolymer emulsion.

Admixtures: Generally, they can selectively participate in admixtures such as superplasticizers, plasticizers, retarders, early strength agents, antifreeze agents, rust inhibitors, etc.: When the product contains steel reinforcement materials or steel embedded parts No calcium chloride-based additives may be used.

Other data: The selective increase of some pozzolanic activity data will help improve the induction of GRC products, such as strength, impermeability, and durability.
