DIRECTION OF USE
For onsite machine mixing - Small quantity of water is dosed in empty drum to clean the drum after each batch. Add fibre in the rotating drum. Then add chips/sand/cement/water in the concrete mixer and continue normal operation.

For dosing in Ready Mix Truck - Add fibers in small lots in the rotating drum. After dosing is complete allow extra 20-30 revolutions of drum at maximum RPM.

For Manual Mixing (CPP06/12) - Put fibers in a bucket of water and stir it so that fibers disperse in water. Spread the water and fibre mixture on the dry cementatious mix.

TYPES OF THE CETEX CONSTRUCTION FIBRES

(All these fibres conform to ASTM C 1116/C 1116M - 06 4.1.3 Type III &
BS EN 14889-2:2006.)

CPP06
These are polypropylene fibers of 6 mm length. They are mainly used in plasters for finishing coat or ornamental castings for crack prevention as well as additional reinforcement. Suitable care has been taken to insure dispersion of fibres for hand mixing of mortar.
Diameter - 24 micron; Aspect ratio - 250

CPP12
These are polypropylene of with 12 mm length. They are used in mortar mix where the thickness of application of the mortar is 10 mm or more. They are suitable for initial coat of plaster, waterproofing of structure. They are also added in concrete for additional reinforcement, where mixing is manual.
Diameter - 24 micron; Aspect ratio - 500

CPP24
These are polypropylene fibers of 24 AcA A 25 mm length. They are used in concrete mixing machines. Being on border line between micro & macro fibres, it prevents crack formation and provides reinforcement. It is suitable for crack prevention in concretes, where maximum size of aggregate is 19-20mm. Being longer than maximum size of aggregate, each and every strand is effective. They are used for various concrete application.
Diameter - 30 micron; Aspect ratio - 833

CPP50
These are polypropylene fibres of 48-51mm length. The longer length, results in better reinforcement, thereby improving the strength of the concrete. They are used in concrete for higher strength.
Diameter - 38 micron; Aspect ratio - 1200

CPPST (Structural Graded Fibers)
These are graded (mixed length) polypropylene fibers. They are suitable for various concrete structural works. It can be used to decrease or replace the steel in concrete, particularly in floors and certain pre-cast. Mostly it is a blend of CPP24 and CPP50. Due to the long length of CPP50; they give better anchorage and reinforcement while CPP24 increases the number of fibres in a given dosage, preventing crack formation. It has been found that graded fibers give better result compared to individual length fibers. It is recommended for heavy structural concrete/load bearing structures. It is the most popular for concrete application.
