Profskrin RC 451 RLq — flowable R4 repair mortar for fast-track work
Profskrin RC 451 RLq, based on special cements, is designed for structural repair of concrete and reinforced concrete within tight deadlines: compressive strength reaches 3 MPa after 40 minutes, 8 MPa after an hour, 15 MPa after 2 hours and 45 MPa by 28 days. The flowable R4 mortar to GOST R 56378 is used to replace sleepers and short sleepers in track concrete, to repair cement-concrete road pavement slabs and platforms, to grout under the bearings of bridge spans and to pour equipment foundations. It is resistant to de-icing agents, grades W16 and F2 400.
