REKS® R4 — mortar for structural repair of reinforced concrete, 60 MPa
Structural repair and restoration of reinforced concrete structures are the main task of REKS® R4, a non-shrink fibre-reinforced thixotropic mortar of class R4 per GOST R 56378. It is used for local repair of damaged and deteriorated elements in interior and exterior work on vertical, horizontal and overhead surfaces — in industrial buildings, on columns, beams and hydraulic structures. Compressive strength is at least 25 MPa after one day and 60 MPa after 28 days, flexural strength at 28 days from 9 MPa, and flowability is retained for at least 45 minutes.
