Profskrin RC45-1.25 F — winter fine-grained thixotropic R4 mortar

Thixotropic repair mortars

Profskrin RC45-1.25 F, the winter version of the fine-grained mortar with 1.25 mm aggregate, is used for structural repair of concrete structures at temperatures from −10 to +10 °C. After placing, an above-zero temperature is maintained for 3 days under protective enclosures; the mix stays workable for 10–15 minutes. Class R4, compressive strength from 20 MPa after 24 hours and from 45 MPa after 28 days, water impermeability W16, shelf life in paper bags 6 months.
