REKS® Strukto 60 — fibre-reinforced thixotropic R4 repair mortar, 60 MPa
Non-shrink fibre-reinforced R4 mortar for repairing bridges, tunnels, dams and columns; compressive strength at 28 days at least 60 MPa.

The density of hardened REKS® OL is only 1.5 t/m³, so this non-shrink thixotropic mortar is chosen for overhead concrete surfaces and extensive damage where a low weight of the repair material matters. The mortar belongs to class R3 per GOST R 56378 and is used to repair elements of concrete and reinforced concrete structures in industrial buildings, on columns, beams, tanks and treatment plants. At 28 days compressive strength is at least 35 MPa and bond to the substrate from 1.5 MPa; packed in 20 kg bags.
