What is the difference between GRC wallboard and aerated block wall?
GRC composite wall board with low alkalinity cement mortar material, alkali resistant glass fiber as reinforcing material, made of plate surface layer, built of reinforced concrete rib, and the thermal insulation material is filled in the core, the new light composite wallboard made of a pedestal.
GRC composite wall refers to the low alkalinity cement mortar material, alkali resistant glass fiber as reinforcing material, made of plate surface layer, the cast or prefabricated, and other new light insulation composite wall material insulation material compounded.
Because of the composite structure of GRC surface layer and high thermal resistance core material, GRC composite wallboard has high strength, high toughness, high impermeability, high fire resistance and weather resistance, and has good insulation and sound insulation performance.The surface material for producing GRC composite exterior wall panels is the same as other GRC products. The core layer can be matched with cast-in-situ cement expanded perlite mixing material, or prefabricated insulation materials (such as rock wool board, polystyrene foam board, etc.). Generally, the anti - roll forming process is adopted. When the molding is made, the face of the wallboard is contacted with the surface of the template, so the quality of the face of the wallboard is better. The GRC surface of wallboard is usually made by direct injection method. The built-in reinforced concrete ribs are made of welded steel frames and C30 bean stone concrete made from sulphoaluminate cement.
