Vetonit remokor T-45 — thixotropic class R4 mortar on cement with polymers

Thixotropic repair mortars

Vetonit remokor T-45, based on special cement with polymers, aggregate up to 1.25 mm and polymer fibre, is a non-shrink thixotropic class R4 mortar with increased crack resistance. It is applied with a trowel or a plastering machine in the repair of reinforced concrete for general, industrial and special purposes, including on vertical and overhead surfaces and in structures in contact with drinking water. The compressive strength is at least 45 MPa at 28 days, the bond to the substrate 2 MPa, frost resistance F₁600, water impermeability W10.

Specifications

ManufacturerVetonit — OOO “Saint-Gobain Stroitelnaya Produktsiya Rus”, Arzamas
Typethixotropic repair mortars
Useindustrial buildings
Basefine-grained dry mix, maximum aggregate size 1.25 mm, with polymer fibre; binder — special cement and polymers; non-shrink, thixotropic, non-segregating compound with increased crack resistance
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); treat smooth or unevenly absorbent substrates with “remokor 05” and apply onto the fresh layer; water 3.6–4.2 l per 25 kg; 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
