ROCKCRETE SF3060
DESCRIPTION
ROCKCRETE SG3060 steel fibres are designedspecifically for the reinforcement of concrete, mortars and other cementitious mixes. ROCKCRETE SF 3060 is a low carbon wire deformed with hooked ends to provide optimum performance within the concrete mix. ROCKCRETE SF 3060 steel fibres are European Standard EN 14889-1:2006 compliant and have been specifically designed to meet or exceed the defined performance requirements.
FEATURES / ADVANTAGES
- Provides uniform multi-directional concrete reinforcement
- Increases crack resistance, ductility, energy absorption or toughness of concrete
- Improves impact resistance, fatigue endurance and shear strength of concrete
- High tensile strength fibre bridging joints and cracks to provide tighter aggregate interlock resulting in increased load carrying capacity
- Provides increased ultimate load bearing capacity which allows possible reduction of concrete section
- Requires less labour to incorporate into concrete than conventional reinforcement
- Offers economical concrete reinforcement solutions with greater project scheduling accuracy
- Ideally suited for hand or vibratory screeds, laser screeds and all conventional finishing equipment
APPLICATIONS
- Ground supported slabs
- Suspended ground slabs
- Jointless floors
- External roads & pavements
- Precast
- Overlays
- Walls
Blast – Resistant Concrete

DIRECTIONS FOR USE
MIXING DESIGNS AND PROCEDURES
ROCKCRETE SF3060 steel fibres can be added during or after the batching of the concrete but should never be added as the first component. Such devices as conveyor belts, chutes and dispensers may be used to add fibres to the mixer at the ready mix plant. After the fibres have been added, the concrete should be mixed for sufficient time (minimum 5 minutes at full mixing speed) to ensure uniform distribution of the fibres throughout the concrete. The use of mid or high-range water reducing admixtures can be advantageous, but is not essential.
