The winter flowable mortar with fine aggregate (size 1.0 mm) is designed for shallow damage on horizontal and slightly inclined surfaces and is placed at sub-zero temperatures down to −20 °C without heating. Ultra-rapid strength gain gives 15.0 MPa after 2 h and 25.0 MPa after 24 h, and 60.0 MPa (B50) after 28 days. The mix with polymer fibre is used for urgent structural repair of roads, airfields, bridges, floors and equipment foundations; watertightness W16, frost resistance F1 600.
