Vetonit remokor L-60 — high-strength flowable mortar, class R4

Flowable repair mortars

The flowable Vetonit remokor L-60 is used for levelling and repairing horizontal surfaces, bridge slabs and beams, hydraulic structures, roads and airfields, as well as for monolithic filling of joints and strengthening foundations. The non-shrink class R4 mix based on high-strength cements and sand up to 3 mm with polymer fibre is poured into formwork from one side and flows under its own weight. After 1 day it reaches at least 30 MPa, after 28 days 60 MPa, frost resistance F₁1000 / F₂300, water impermeability W16.

Packagingthree-ply paper bag with a polyethylene middle ply, 25 kg
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 50 mm at a time — a stiffer mix
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
