• Polypropylene fibres for concrete - BETON-FIB 23; 30; 34 and BETON-ZBROJ

    Beton-Fib Fibres

    are polypropylene microfibres with a circular cross section and an additional aperture which allows for their even distribution in mortar or concrete.

    Beton-Zbroj Fibres

    are a bundle created from polypropylene bands in a standard or fibrillated form (in that case, the band decomposes into a characteristic net). As a result of mixing, the bundle splits into many small pieces, which decompose evenly in all directions.

    Beton-Fib 23, 30, 34 and Beton-Zbroj polypropylene microfibres for concrete are designed for non-structural use with concrete, mortar and slurry. They are perfect for a very wide range of concrete works. The use of microfibres is very simple; it does not require any changes in the formulas nor in the methods of mixing and no additional care treatments. They can be used with all concrete additions or admixtures and using various technologies. Surface processing (levelling, smoothing and finishing) should be done using standard tools.

    Advantages and benefits:

    • they eliminate the need to use contraction steel meshes
    • they prevent scratches and shrinkage cracks efficiently
    • they eliminate surface cracks
    • they improve coherence and the even distribution of concrete
    • they improve resistance of fresh concrete
    • they increase wear resistance
    • they limit concrete and reinforce steel corrosion
    • they significantly increase concrete fire and they are frost resistance
    • they limit creation of concrete chips during fire
    • they decrease absorptivity and water permeability of concrete
    • they do not require additional care treatments
    • they do not require any changes in proportion to other components
    • they are chemically neutral and resistant to acids, salts and alkalis
    • they are light, easy and safe to use and they eliminate the danger of injuries
    • their use decreases the wear of machines and equipment (concrete mixers, pumps)
    • their use decreases time and costs of construction
    • they decrease costs of transportation and storing in comparison to steel fibres

    Usage::

    • as an addition to mortars, masonry and plastering mixes
    • as an addition in case of wet shotcreting
    • for the production of, for example, roof tiles, paving tiles, kerbs, etc.
    • for the construction of ceilings, retaining walls and concrete floors
    • for the construction of roads, parking spots, airports
    • for the construction of autoclaved cellular concrete
    • for the production of industrial floorings, ramps and factory sites
    • for the production of tunnels, wharfs, breakwaters, water collectors, etc.

    Exemplary use*

    The fibres should be added in a ratio appropriate for the assortment produced. The fibres should be added to s wet mass after adding aggregate, but before concrete and water. Mix for several minutes to evenly distribute the fibres. 5 minutes of mixing should guarantee that the mixture will be ready, but the final effect of mixing should be checked by evaluating the concrete consistency by way of organoleptic examination. Fibres can also be added to ready concrete mixtures in a concrete mixer truck, whose gear should be shifted to the top one and then, everything should be mixed for about 4-6 minutes.

    Exemplary parameters of microfibres

    The length of the added fibres depends mainly on the thickness of grains which are present in given mortar or concrete, as well as on the designation of the material produced.

    Exemplary use*

    • 6 i 12 mm - mortars, thin-layer masses
    • 19 mm - concrete floors, small size precast concrete products, precast concrete flooring elements
    • 30; 40 i 60 mm - ready-mixed concrete
    • 60 mm - foundations, ceilings, containers, road and bridge engineering objects.

    Proposed dosing*

    • 0,3 kg/m³ - mortars
    • 0,6 kg/m³ - standard concrete types
    • 0,9 kg/m³ - concrete of higher strength parameters

    Beton-Fib and Beton-ZBROJ microfibres have undergone all tests required by law. They comply with the requirements of PN-EN 14889-2. They have a Declaration of Performance and bear the CE mark. They do not release dangerous substances.

    Beton-Fib and Beton-ZBROJ microfibres for concrete cannot be used as a replacement for constructional reinforcement or in order to decrease the designed thickness of concrete elements.
