Fibermesh polypropylene fibres are manufactured from 100% virgin polypropylene, in the world’s largest and technologically most advanced plant in the world (for Synthetic fibers for concrete) to ISO 9002 and ISO 14001 quality assurance standards. Further, Fibermesh fibres are specially engineered for use in concrete and mortars as a secondary reinforcement and are designed to provide an uniform three dimensional distribution without any clogging or clumping.
Fibermesh fibres are manufactured in the following forms:
Monofilaments (bundles of thin individual monofilaments) i.e. our `STEALTH’ fibres – These are the economical fibres which can be used in general reinforced concrete, light duty industrial floor slabs, driveways and parking areas in residential / commercial buildings, aesthetic concrete elements, plasters and for preventing explosive spalling of concrete due to fire, water retaining structures etc. Available also now Stealth e3 Multidimensional graded fibres (The only of its kind in the world) which are also capable of mixing in handmixed plasters.
Fine Fibrillated fibres (bundles of interconnected strands which open up during the mixing process) i.e. our `Harbourite’ fibres – These are superior technology fibres for use in Plaster, Gunite and Precast elements and are the only fibres in the world which can even mix in dry mortars like gunite.
Graded Fibrillated fibres (Thick bundles of interconnected strands which open up during the mixing process) i.e. our `Fibermesh Inforce e3 fibres – These are the world’s most advanced fibres for use in reinforced concrete, marine structures, concrete subject to seismic forces, heavy duty industrial floor slabs, concrete pavements, water retaining structures, machine foundations, for superior concrete toughness and to provide post crack residual strength.
Antimicrobial fibres i.e. our `Microblocker’ fibres – These fibres are manufactured with an antimicrobial agent which enables the fibres to fight and prevent the growth of Thin cell wall micro organisms such as bacteria, fungi, yeast, mold and mildew in or on the concrete/mortar surface, and, most importantly, function for the life of the concrete/ mortar.
Fibermesh fibres conform to ASTM C-1116 and ASTM C-1018 performance requirements and have received certification by the British Board of Agreement and other internationally recognised institutions such as Underwriters Laboratories and Omega Point Laboratories. Therefore, Fibermesh fibres account for over 75% of the world market for Synthetic fibres for concrete, due to their proven track record and consistent performance all over the world.
Fibermesh fibres provide the following quality benefits to concrete and cement mortar
Fibermesh fibres ensure a homogeneous concrete mix without segregation problem taking place, thus ensuring a uniform concrete quality and consistency all through out, resulting in denser concrete mix with drastically reduced honeycombing and bleeding problems.
Fibermesh fibre ensures much more cohesiveness to concrete, enabling smoother pumping operation with reduced choke up problem on site, ensuring better quality and faster completion of work.
Fibermesh fibres reduce shrinkage cracks by over 90% and also provide effective crack control to temperature cracks and thermal cracking in mass concretes.
Fibermesh fibres enable a much better compaction of concrete on site, by allowing vibration for much longer period with reduced bleeding, thus ensuring better concrete quality.
Fibermesh fibres allow for the moisture in concrete to be retained in the mix for much longer period by reducing bleeding by 50 to 60%, ensuring much better hydration of the cement and therefore better concrete quality and durability.
DURABILITY AND PERFORMANCE BENEFITS
Fibermesh fibres reduce shrinkage cracks and improvement in the concrete quality result in drastic reduction in permeability to the extent of 79%, ensuring almost water tight concrete structures and plasters.
Fibermesh fibres reduced permeability of the concrete also protects the steel reinforcement from corrosion by preventing ingress of water and other harmful pollutants.
Fibermesh fibres effectively double the corrosion free life of steel reinforcement in reinforced concrete structures, even in aggressive environments.
Fibermesh fibres double the impact resistance of concrete making concrete much more tough and also increase absorption resistance by 50%, thus ensuring extremely durable and long lasting concrete, in pavement and industrial floor slabs.
Fibermesh fibres increase shatter resistance of concrete by 4 to 5 times, providing a very high energy absorption capacity and ductility to the concrete making it more resistant to seismic force or vibratory forces, ensuring greater safety to structures and people using the structure.
Fibermesh fibres prevent explosive spalling of concrete due to fire by allowing entrapped moisture to escape at high temperature, by the fibers melting and providing millions of microscopic vapour channels, thus protecting the concrete from suffering any explosive spalling due to fire.
Fibermesh fibres drastically reduce costs towards patch up repairs in slip formed constructions and in general reinforced concrete elements by ensuring a much better overall concrete quality.
Concrete materials are very brittle when subjected to normal stresses and
impact loads. There has always been a need to add reinforcement to concrete> to compensate for this lack of ductility. In many cases, the concrete member is
kept intact using steel bars or welded wire fabric reinforcement in one or two
locations of potentially high stress. If the concrete cracks, the concrete is
hinged together at those limited locations.
The introduction of randomly distributed steel fibre reinforcing throughout the
concrete mix transforms the hardened concrete material into a more flexible
composite system. The tensile stresses of the concrete are not just compensated
for in one or two locations. The concrete material is reinforced throughout
the entire concrete section, in multiple directions. Steel fibre reinforced concrete
is able to withstand much greater stresses, both prior to and after cracking.
Homogeneously reinforced concrete has substantially greater fatigue and
impact resistance than conventionally reinforced materials, greatly reducing
the potential for fractures and spalling. If the concrete should crack, steel fibre
reinforcement is able to minimize the crack width.
All Novocon steel fibres are ASTM A820 compliant Type I steel fibres made from high tensile steel cold drawn steel wire and specially engineered for use in concrete to provide numerous quality, durability and performance enhancement
Novocon steel fibres, are available in the following types.
Xorex - Continuously deformed steel fibre, which is the versatile fibre for all general applications, such as heavy duty industrial flooring, precast projects, concrete pavements etc. This fiber is now being manufactured by us in India, under full technical collaboration of M/s. S.I. CONCRETE SYSTEMS, U.S.A. to their precise specification and quality standard to enable us to offer you a more competitive price.
Novotex - Novotex steel fibres with a flattened end having higher tensile strength for specific applications requiring higher level of toughness, as compared to Xorex steel fibres. Novetex steel fibre is currently being imported.
ISF - ISF steel fibres are undulating round fibres having very high tensile
steel fibres used in applications in roads, factory floors, shotcrete.
Improve impact resistance, abrasion resistance and toughness of concrete.
Improve shatter resistance and ductility of the concrete.
Can be used as a replacement of conventional steel reinforcement in ground supported slab, composite metal deckings and shotcreting works to save cost and time and provide better quality and performance.
