EMACO® Nanocrete R4 Fluid
Single component, high strength, high modulus, fibre reinforced, shrinkage compensated, flowable structural repair mortar
Emaco® Nanocrete R4 Fluid is designed for the following repairs:
- columns, cross beams and piers of all bridges
- marine and other civil structures
- water treatment and sewerage facilities
- large area structural repairs using the formwork and casting method
- areas of congested reinforcement where hand or spray application is not possible
Useful facts
- pack size: 25 kg
- water addition: 3.5 to 4.0 litres/bag depending on consistency required
- consumption: each 25 kg bag covers 1.25 m2 at 10 mm thick
- setting time: 300 min. (initial), 380 min. (final) at 21 ºC
- minimum application temperature: > 5 °C
- shelf life: 12 months in unopened sacks
- curing: in hot, dry or windy conditions ensure correct curing using a MASTERKURE curing compound after removing formwork
Technical data
- very high compressive strength (class R4 in EN 1504 part 3) > 55 MPa at 28 days
- high strength gain during early age curing > 20 MPa at 24 hours
- high modulus of elasticity (EN 1504 part 3 class R4) > 25 GPa at 28 days
- long open time ensures consistent flow of material
- formulated with new nanotechnology, shrinkage compensation systems, with fibre reinforcement to minimise cracking
- high sulphate resistance
- max. grain size < 4 mm
Flowable but high strength structural repair mortar
- for concrete replacements up to 200 mm thick in one layer
- long open time
- no segregation or bleeding
- for pourable or pumpable application
- extra low shrinkage for durability
- only simple standard surface preparation required
- high flow for full compaction even in areas with congested steelwork
