Vetonit remokor T-60 — high-strength thixotropic mortar, class R4

Thixotropic repair mortars

Beams, including prestressed ones, floor slabs, bridge slabs, pylons and piers are repaired with the thixotropic Vetonit remokor T-60 of class R4. The non-shrink mix based on special cement with aggregate up to 3 mm and polymer fibre, without metallic aggregates or chlorides, is applied with a plastering machine or a trowel “wet on wet” onto remokor 05 or onto a primer coat of the same mortar. After one day the compressive strength is at least 25 MPa, after 28 days 60 MPa, frost resistance F₁1000 / F₂300, water impermeability W16, combustibility group NG.

Specifications

ManufacturerVetonit — OOO “Saint-Gobain Stroitelnaya Produktsiya Rus”, Arzamas
Typethixotropic repair mortars
Usebridges and overpasses, columns and beams, hydraulic structures and dams, industrial buildings, roads and airfields
Basedry mortar mix, maximum aggregate size 3 mm, with polymer fibre; binder — special cement; no metallic aggregates or chlorides; non-shrink compound
Colourgrey
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; mechanically with a plastering machine (wet spraying) or by hand with a trowel; without “remokor 05” a primer coat of the same mortar in a more fluid consistency is mandatory, scrubbed in with a stiff brush, main layer “wet on wet”; smooth with a float after setting; thicker than recommended — in several layers
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
