Autumn and spring repair of shallow concrete damage is the task of the fine-grained BM mix with 1.0 mm aggregate and polymer fibre, which is placed at temperatures from −10 to +7 °C. The flowable mix with rapid strength gain is used for urgent structural repair of horizontal and slightly inclined surfaces of floors, roads, airfields, bridges and equipment foundations. After 2 h it gives 10.0 MPa in compression, after 28 days 50.0 MPa (B40), W18, F1 600, class R4.
