Class B70 and self-levelling ability set this winter flowable mix apart: after 24 h it reaches 55.0 MPa, after 28 days 80.0 MPa in compression and 10.0 MPa in flexure (Btb8.0). The coarse-grained mix with polymer fibre is placed without heating at sub-zero temperatures down to −20 °C on horizontal and slightly inclined surfaces. It is used for urgent restoration of spalls, gouges and delaminations of concrete and reinforced concrete in industrial buildings, on roads, airfields, bridges and equipment foundations; W20, F1 800.
