Profskrin RC80 Lq, the flowable counterpart of RC80, is intended for structural repair of concrete structures of strength class B60 and above. The mix, based on Portland cement with mineral filler and 3 mm aggregate, is poured at temperatures from +5 to +30 °C. After 24 hours it reaches from 35 MPa in compression, after 28 days from 80 MPa, in flexure 5 and 10 MPa; water impermeability W16, frost resistance F1 1000 and F2 300.
