Its flowable type distinguishes Profskrin RC45 Lq from the thixotropic RC45, with the same class R4. It is used for structural repair of load-bearing building and bridge structures, treatment and industrial facilities, underground ducts and pipelines. Compressive strength from 15 MPa after 24 hours and from 45 MPa after 28 days, bond to the substrate from 2 MPa, water impermeability W12, frost resistance F1 600 and F2 200, aggregate size 3 mm.
