Polypropylene fibre is a synthetic reinforcement, manufactured of 100% polypropylene fibres, containing no reprocessed olefin materials designed for use with all cementitious mixes. Polypropylene synthetic fibres are easily available in India.

Polypropylene fibres were first suggested as an admixture to concrete in 1965 for the construction of blast resistant buildings for the US Corps of Engineers. Since then, the use of these fibres has increased tremendously in construction of structures because addition of fibres in concrete improves the toughness, flexural strength, tensile strength and impact strength as well as failure mode of concrete. Polypropylene twine is cheap, abundantly available, and like all manmade fibres, of a consistent quality.

The polypropylene fibres reinforced the performance under not only compression, flexure, and tension, but also under impact blows and plastic shrinkage cracking.

We introduce ourselves as manufacturers of Bajaj Fibre Tuff Macro Synthetic Fibres. It can be used effectively in industrial flooring, tunnel shotcreting, metro concrete structures, basement slabs and dams, to enhance tensile performance in comparison to the ordinary RCC. The application of these fibres in construction improves the tensile strength, flexural strength, toughness, impact strength. Polypropylene fibres are used in dosage of 3-9 kg/m3 (14889-II) for infrastructure projects and precast concrete.

Fibre Tuff is a macro synthetic fibre designed specifically for the reinforcement of concrete and other cementitious mixes. Fibre Tuff have an engineered contoured profile, which serves to effectively anchor the fibre into the concrete, thus resisting matrix pull out and enhancing the concrete’s performance even after it has developed stress cracks.

The PP Fibre is generally included within a concrete mix or cementitious mixes. It has been tested for all its major properties as per its standardized by IRC, MORTH, approved Indian engineers, consultant and authorities for use in their projects.

Benefits of PP Fibre:

– Redistribute load
– Increase ductility/toughness
– Eliminates corrosion long term durability
– Reduces permeability
– Improves shrinkage and temperature crack control
– Safer and lighter to handle than steel
– 85% reduction in carbon footprint
– Strong bonding with the concrete
– Increases post crack load capacity
– Speed up construction by eliminating steel mesh set up
– Reduces wear on concrete pumps and hoses

We are successfully supplying Bajaj Fibre Tuff to:

– MSRDC Samruddhi Mahamarg
– Mumbai Metro
– RVNL Rishikesh-Karanprayag
– RVNL Budhni Barkheda
– MMRDA

Dosage:

Fibre Tuff has regular dosage of 3 to 9 kg per cubic metre of concrete. The dosage rate is decided as per structural toughness. We suggest you to contact your Bajaj Reinforcement representative before using so that we can discuss together the application.

Pumping:

Fibre Tuff can be pumped through 50 mm rubber Hoses without difficulty. Hose life increases against steel fibre, saving time and money.

Mixing:

The fibre is best dispersed when added to a drum/pan mixer.

Handling and Storage:

Fibre Tuff is packed as per requirement and supplied on durable, recyclable plastic bag.
