The corundum aggregate makes FC80 Cr a more wear-resistant dry-shake topping option: abrasion no more than 0.15 g/cm², compressive strength at 28 days at least 80 MPa. The mix is applied by the dry method onto fresh concrete of class no lower than B22.5 and floated with power trowels. It is designed for high abrasion and moderate impact loads indoors and outdoors and withstands service from −50 to +200 °C. Acids and salts are contraindicated for it.
