Polypropylene Fiber for Cement-based Concrete

Polypropylene Fiber effectively control the microcracks resulting from ductile shrink of concrete,dry shrink and variations of temperature, prevent and constrain the from and development of cracks. As a new kind of reinforcement fibers for concrete,

the polypropylene fibers have becoming a focus on research and application  of  fibrous  concrete  science  after  glass  fiber  and  steel  fibers.

Properties of  Polypropylene Fiber

Density g/cm3 : 0.91

Length(mm) : 12,15,17,19

Acid and Alkali resistance : strong

Tensile Strength (mps) : 400 min.

Melting Point (Deg.C) : 160--175

Function of Polypropylene Fiber Reinforced Concrete   

Polypropylene Fibers have obvious advantages of its single fiber slim in length,large in amount after fully spread out in concrete,comparing with steel fibers,and they are characterized by their resistance to moisture and chemicals,and low in elastic modulus so made improvements in concrete performance in the following aspects:Constrain cracks resulted in ductile shrinkImprove permeabilityImprove abrasion resistanceImprove tensile strengthcapability of impact and fatigue Prevent and stave off  main structural bars from erosionReplace other forms in controlling nonstructural cracks
