Technical specifications of polypropylene fibers

Polypropylene fibers,also  known as  polypropylene  short fibers,concrete crack resistant fibers,PP crack resistant fibers,Dura fibers,and synthetic fibers.
Polypropylene fibers can effectively  improve the crack  resistance,impermeability,    impact  wear  resistance,frost  resistance,blast  resistance,and  workability  of  mortar/con- crete,preventing shrinkage  cracks  in  mortar/concrete;Improve  the  denaturation  and toughness of concrete.Tens of millions of fibers are evenly distributed in mortar/con-  crete,playing a good role in micro reinforcement,which maintains the integrity of the structure,avoids scattering into many fragments when the structure is damaged by impact,prevents corrosion of steel bars in the structure,greatly extends the service life of the project,and reduces maintenance costs.

Construction  suggestions

1.For ordinary plastering mortar,it is recommended to add 0.9-1.2kg of mortar per square meter.Generally,1kg/m³
2.Itis recommended to add 1-3 kg of insulation mortar per ton
3.The recommended concrete dosage for each cubic meter is 0.6-1.8kg,usually 0.9kg/m³
