Pakol Remontny 600 M — fine-grained thixotropic R4 mix for walls and ceilings
Fine-grained thixotropic R4 mortar for structural repair of shallow spalls on bridges, in tunnels and on columns; watertightness W18.

The winter high-strength model of the thixotropic range combines placing in frost down to −20 °C without heating with ultra-rapid strength gain: 28.0 MPa after 4 h, 55.0 MPa in compression after 24 h. The coarse-grained mix with polymer fibre is used for urgent structural repair of walls, ceilings, columns and beams on bridges, in tunnels, on dams and tanks. After 28 days: 80.0 MPa (B60), flexural 10.0 MPa (Btb8.0), W20, F1 1000.
