GROUT 2 SFR
Rheoplastic, shrink-proof, fibre-reinforced mortar for precision anchorage
Code: GRT.0262
Components: 1
Appearance: Powder
GROUT 2 SFR is a high-performance, self-levelling castable mortar, being fibre-reinforced with READYMESH MM-150 steel fibres and READYMESH PM-060 polypropylene microfibres, with high flexural strength, great adhesion to concrete and steel, and shrinkage compensation. Aggregates with a maximum size of 2 mm. It is ideal for restorations, reinforcements and seismic adjustments, offering ductility for medium thicknesses (3–10 cm), on structures in reinforced concrete and masonry.

Use fields
Precision anchorage of operating machines: presses, turbines, power supply units, rolling mills, alternators, overhead cranes, metal structures, tracks, etc.. Structural adaptation, renovations, drawing and reinforcements, using injections and castings inside formworks. Creation of connection anchorage using steel bars with a diameter and depth consistent with the project specifications, by casting in specifically prepared perforations. Construction of structural road joints.
Preparation of supports
The application surfaces should be clean, free of containment, inconsistent and incoherent parts, dust, etc., conveniently saturated with water to reach the "saturated to dry surface" condition. An adequate roughening of the surfaces by scarifying, sandblasting etc. is always necessary in order to obtain the maximum adhesion values to the substrate. The optimal values are obtained with high pressure hydro-scarification. Bare the irons undergoing disruptive oxidation or deeply oxidized, removing the rust of the exposed irons (by sandblasting or abrasive brushes).
Use method
Place 2/3 (approx 2.5 litres per bag) of the total water in the mix, then gradually add the product and the remaining water, mixing until you obtain an even mix with the desired consistency and no lumps.
Application methods
- Pour out
Tool cleaning
- Water
Permitted supports
- Concrete
- Mixed walls (bricks and stones)
- Prefabricated concrete
- Rusty reinforcement rods
Warnings, precautions and Ecology
Given the self-levelling properties of the product and its self-compacting capacity, you are advised to pay due attention to the vibration phase. Excess zeal in the vibration operation could worsen the aesthetic performance of the resulting manufactured work.
Do not use in the absence of adequate side confinements.
Ensure protection and damp seasoning of the surfaces exposed.
Implement casting procedures capable of ensuring the absence of vacuums and cracks; grout the mortar from one part of the perimeter of the casting to avoid air sacks.
