REKS® AR — thixotropic R4 repair mortar for spraying and trowel application
Wet spraying and trowelling are the two application methods for REKS® AR, a non-shrink fibre-reinforced thixotropic mortar of class R4 per GOST R 56378. Unlike AR FM, it is supplied as a single 25 kg bag, without a separate pail of fibre. The mortar restores elements of bridges and overpasses, tunnels, dams, tanks and industrial buildings, prestressed beams and columns; at 28 days it reaches at least 55 MPa in compression and 7 MPa in flexure.
