Grades 800 K and 1000 K are combined in one item: to GOST 31358-2019 the first corresponds to class B70 and the second to B80; both have W20, F1 1000 and a modulus of elasticity of 27.0 GPa. The high-strength coarse-grained non-shrink mix with polymer fibre is intended for structural repair of deep damage to floors, roads, airfields, bridges and equipment foundations. After 28 days grade 800 K reaches 80.0 MPa in compression and 1000 K 100.0 MPa; in flexure 12.0 and 14.0 MPa respectively.
