Profskrin RC45-1.25 — thixotropic R4 mortar with fine 1.25 mm aggregate

Thixotropic repair mortars

The index 1.25 in the designation Profskrin RC45-1.25 is the aggregate size in millimetres: it is smaller than in the basic RC45 mortar, with the same class R4. The thixotropic mix is intended for structural repair of concrete structures, columns and beams of industrial buildings. After 24 hours it reaches from 20 MPa in compression, after 28 days from 45 MPa, bond to the substrate at least 2 MPa, water impermeability W16, frost resistance F1 1000.
