Profskrin RC80 — thixotropic R4 mortar for concrete of class B60 and above

Thixotropic repair mortars

Profskrin RC80 is chosen when the concrete or reinforced concrete under repair is of class B60 and above. By 28 days the mortar reaches at least 80 MPa in compression and 10 MPa in flexure, and after 24 hours 35 and 5 MPa. It can be applied by hand or by machine, including on walls and ceilings; water impermeability W16, frost resistance F1 1000 and F2 300, service in environments with pH from 5 to 14.
