NO KRACK

Chemically Surface Modified Straight Fibers + Fibrillated Tapes based concrete additives in Graded lengths

Chemically Surface Modified Straight Fibers + Fibrillated Tapes based concrete additives in Graded lengths


DATA SHEET

100% Virgin high tenacity polypropylene straight fibers + fibrillated mesh fiber in graded lengths, with Chemical Surface Treatment for uniform dispersion in wet concrete, in multiples of 10mm & 20mm to give 3D micro-reinforcement. This is to be used as micro-reinforcement at minimum of 900 g / m3 of concrete. NOKRACK complies with ASTM C 1116, ACI committee report 544-1R

FUNCTIONS

  1. Increases water proofing ability of concrete (reduces permeability).
  2. Reduces need to do water proof plaster, pressure grouting etc.
  3. Reduces shrinkage and plastic cracking in concrete.
  4. Makes the concrete dense & strong.
  5. Protects steel.
  6. Use for roof slabs, toilet floor slabs, water & effluent / sewage tanks etc.

AREA OF APPLICATION

Roof slabs, wet slabs, toilets, bathrooms, utility areas & kitchens. Water retaining structures, Effluent treatment tanks, Gunite / shotcrete, Ferrocrete tanks, Warehouse Flooring, Rafts, Basement Waterproofing-Overlays, Toppings Concrete Tanks

DOSAGE

For Concrete, minimum 0.9 kg/m3 of concrete i.e. @125 g/ 50kg bag of cement.


MIX DESIGN

NOKRACK is phsical micro-reinforcement - hence additional water is not required.


MIXING PROCESS

Mix directly in the concreate mixer @ 125g/50kg of cement or 900 g/m3


NOTE

Fiber Based Concrete Additives should not be used for replacement of structural or load bearing reinforcement.
