Polypropylene Fibers for cement concrete mortar reinforcement

polypropylene fiber, also known as the engineering fiber, concrete fiber, anti-crack fiber, crack-prevent fiber, synthetic fiber or plastic fiber etc.,which is a kind high intensity sarciniform monofilament made of polypropylene through unique production technology. It can effectively control the micro cracks which is caused by concrete or

STUDY THE EFFECT OF POLYPROPYLENE FIBER IN CONCRETE

polypropylene fibers to concrete. Thus addition of fibers in cement concrete matrix bridges these cracks and restrains them from further opening. In order to achieve more deflection in the beam, additional forces and energies are required to pull out or fracture the fibers. This process, apart from preserving the integrity of concrete, improves the load-carrying capacity of structural member ...

01/06/1983  In hardened concrete, polypropylene fibers act as crack arresters. Like any secondary reinforcement, the fibers tend to stop cracks from propagating by holding the concrete together so cracks cannot spread wider or grow longer. However, since polypropylene fibers are distributed throughout the concrete, they are effective close to where cracks start at the aggregate-paste

Polypropylene Fiber Reinforced Concrete : An Overview

The concrete mixture with polypropylene fibers results in the fewer rate of bleeding and segregation as compared to plain concrete. This is because the fibers hold the concrete together and thus slow down the settlement of aggregates. Due to its high tensile and pull-out strength, the PP fibers even reduce the early plastic shrinkage cracking by enhancing the tensile capacity of fresh concrete ...
