Vetonit remokor LF-60 — pourable class R4 mortar with steel fibre

Flowable repair mortars

With polymer and steel fibre, Vetonit remokor LF-60 is designed for structures under static and impact-dynamic loads: columns and beams, bridge slabs, dams, retaining walls, silos, cooling towers, airfield and road pavements, industrial floors. The non-shrink, non-segregating, high-flow class R4 mix is poured into formwork and allows elements with rebar corrosion of up to 15 % to be repaired without installing additional reinforcement. The flexural strength is at least 10 MPa at 28 days, the compressive strength 60 MPa, water impermeability W16.

Application methodclean the concrete, remove weak areas (grinding, milling, sandblasting, wet abrasive blasting, shot blasting), wash with pressurised water; clean the rebar and immediately coat it with “Vetonit remokor 05”; dampen the substrate 24 h beforehand and again before the work (matt-damp); water +10…+30 °C, mortar temperature +10…+20 °C; first the minimum amount of water, then the dry mix, mix for 3–5 min with a drill and low-speed paddle or in a concrete mixer, pause 5 min, remix, add the rest of the water if necessary; do not overdose water; pour into strong, watertight formwork soaked with water; pour from one side of the formwork (the pouring side higher and wider), the mix flows under its own weight; for a layer thicker than recommended add washed gravel (crushed stone) 5–10 mm (5–20 mm) in an amount of 50–60 % of the dry mix weight; when pouring 60 mm at a time — a stiffer mix; pour from one side so as not to trap air
Application temperature+5…+35 °C (air and substrate)
Curingkeep moist, protect from precipitation, sun and wind for 5 days; a film-forming curing compound may be used; for 5 days after the work the air and substrate temperature must not be below +5 °C
