Profskrin RC35 is a thixotropic cementitious mortar of class R3 to GOST R 56378 for structural repair of concrete and reinforced concrete columns, beams and other elements of industrial buildings. Class R3 and compressive strength from 35 MPa at 28 days set it apart from the higher-class mortars of the RC range. After 24 hours the mix reaches at least 15 MPa in compression, bond to the substrate is from 1.5 MPa, water impermeability W12, frost resistance F1 600.
