This finely dispersed non-shrink mix with aggregate of only 0.2 mm and Rk7 workability was created for thin-layer structural repair of concrete and reinforced concrete. It eliminates local spalls, gouges, cavities and delaminations on floors, road and airfield pavements, bridges and equipment foundations. Class R4, 28.0 MPa after 24 h, 60.0 MPa in compression after 28 days (B50), F1 400; 2 days of moist curing are required after placing.
