ISF 1050


MIXING DESIGNS AND PROCEDURES: Novocon® ISF1050 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.

PLACING: Novocon® ISF1050 steel fibres can be pumped and placed using conventional equipment. Hand or vibratory screeds and laser screeds can be used with Novocon® ISF1050 steel fibres.

FINISHING: Conventional finishing techniques and equipment can be used when finishing Novocon® ISF1050 steel fibre concrete. In some cases an extra bull float process is advised and lowering the angle of the power float blades will help to minimize fibre exposure on the surface.

DOSAGE RATE: The fibre dosage will vary depending on the type of application, concrete mix design and the performance/ toughness requirements of each particular project. Typically, steel fibre dosage will be in the range of 20 kg to 40 kg per cubic mete . SI® Concrete Systems technical staff can offer advice on dosage requirements once performance requirements have been established by the project designer/enginee .


Novocon® ISF1050 steel fibres are compatible with all curing compounds, super plasticizers, water reducers, hardeners and coatings.


It is recommended that gloves and eye protection be used when handling or adding Novocon® ISF1050 steel fibres to concrete.


Novocon® ISF1050 fibres are available, as standard, in 25kg & 30kg boxes. They are also available upon request in 1000kg bulk bags. The pallets should be protected against rain and snow. Do NOT stack pallets on top of each othe .


SI® Concrete Systems is backed by our team of reinforced concrete specialists who can carefully analyze each project and

provide fibre reinforced concrete design solutions to ensure maximum project performance and cost efficiency.
