monofilament polypropylene fiber

Control the microcracks resulting from ductile shrink of concrete,dry shrink and variations of temperature.


Polypropylene Fibers 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.

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 shrink
Improve permeability
Improve abrasion resistance
Improve tensile strengthcapability of impact and fatigue
Prevent and stave off main structural bars from erosion
Replace other forms in controlling nonstructural cracks
