Nafufill SCC — self-compacting pourable repair mortar, class R4
Nafufill SCC is a rapid-hardening non-shrink concrete mix of class R4 per GOST R 56378-2015 that self-compacts within 15 min without mixing and can be pumped. It is used to repair densely reinforced and prestressed structures of complex shape, for concreting under water and in the zone of variable water level, for cementation and for installing equipment and anchors; if necessary, crushed stone of 5–20 or 20–40 mm is added to the mix. The compressive strength is at least 30 MPa after 1 day and 60 MPa after 28 days, grades W12 and F500, and the material is non-combustible.

|---|---|
| Type | pourable repair mortars |
| Use | hydraulic structures and dams, industrial buildings, equipment foundations, anchoring of rebar and bolts |
| Base | dry concrete mix on a cement binder; self-compacting, non-shrink, rapid-hardening pourable repair compound; crushed stone of 5–20 and 20–40 mm may be added |
| Colour | cement grey |
| Packaging | 25 kg bags |
| Application method | substrate free of dust, oils, grease, laitance and release agents; compressive strength of the substrate concrete at least 25 MPa, pull-off strength at least 1.5 MPa (in the absence of design requirements); dampen to a matt-damp state; pour the dry mix into the measured water (2.5–2.75 l per 25 kg) while mixing continuously in a forced-action mixer or with a slow-speed twin-paddle mixer for at least 3 min; proportions by weight: without crushed stone 100 : 10–11 (mix : water), with 5–20 mm crushed stone 100 : 11.1 : 47.9, with 20–40 mm crushed stone 100 : 11.4 : 47.9 (mix : water : crushed stone); place immediately after mixing, if placing into a defect takes longer than 15 min — light compaction (rodding, vibration); pumping is permitted; do not add binders or admixtures; concreting under water and in the zone of variable water level |
