The steel-fibre modification of the off-season flowable mortar: a coarse-grained mix with steel and polypropylene fibre, rapid strength gain and a working temperature range from −10 to +7 °C. It is used for urgent structural repair of spalls, gouges and delaminations on floors, roads, airfields, bridges and equipment foundations in the autumn and spring period. After 24 h the flexural strength is 9.0 MPa, after 28 days 11.0 MPa (Btb8.0) with a compressive strength of 60.0 MPa (B50).
