Shotcreting in the cold season is the purpose of this fibre-reinforced thixotropic mix: it is applied at temperatures down to −10 °C without heating. The mix is used for structural repair of walls, ceilings and inclined areas of concrete, brick and stone structures on bridges, in tunnels and metro, tanks, on columns and beams. After 24 h: 17.0 MPa, after 28 days: 40.0 MPa in compression (B30), W20, F1 300, class R3.
