Vetonit remokor L-60 — high-strength flowable mortar, class R4
High-strength pourable class R4 mix for repairing bridge slabs, beams, roads, airfields and hydraulic structures; 60 MPa compressive at 28 days.

At air temperatures from −10 to +18 °C work is carried out with the rapid-hardening thixotropic Vetonit remokor NS-40 of class R3, intended for urgent repair and finishing of reinforced concrete, including on vertical and overhead surfaces. First a primer coat of the same mortar in a more fluid consistency is scrubbed in, then the main layer is applied “wet on wet”; only as much is mixed as can be used within 10–20 min. The compressive strength is at least 5 MPa after 2–3 h and 40 MPa after 28 days, water impermeability W12.
| Manufacturer | Vetonit — OOO “Saint-Gobain Stroitelnaya Produktsiya Rus”, Arzamas |
|---|---|
| Type | thixotropic repair mortars |
| Use | industrial buildings, hydraulic structures and dams |
| Base | dry mix based on cement, graded sand (maximum size 0.63 mm) and special additives with polymer fibre; non-shrink, rapid-hardening, fine-grained thixotropic compound |
| Colour | grey |
| Packaging | three-ply paper bag with a polyethylene middle ply, 25 kg |
| Application method | clean the concrete, remove weak areas (grinding, milling, sandblasting, shot blasting), substrate roughness at least 5 mm; at above-zero temperatures dampen 24 h beforehand and before the work, at sub-zero temperatures — do not dampen; mix an amount that can be used within 10–20 min; pour the dry mix into the water, mix for at least 3 min, pause 1 min, remix; temperature of the ready mortar +24…+26 °C; mechanically with a plastering machine or by hand with a trowel; a primer coat of the same mortar in a more fluid consistency is mandatory (scrub in with a stiff brush), main layer “wet on wet”; thicker than 35 mm — in several layers |
| Application temperature | –10…+18 °C (air) |
