Concrete Reinforced with Polypropylene Fibers Concrete ...

1983-6-1  Polypropylene fibers tend to hold the concrete mix together. This slows the settlement of coarse aggregate and thus reduces the rate of bleeding. A slower rate of bleeding means a slower rate of drying and thus less plastic shrinkage cracking. In hardened concrete, polypropylene fibers act

Concrete reinforced with polypropylene fibers

Concrete reinforced with polypropylene fibers Used as secondary reinforcement, plastic fibers help reduce shrinkage and control cracking Polypropylene fibers are manufactured in small, fibrillated bundles (left). In mixing the concrete, the bundles open up and the individual fibers are sheared apart by the fine and coarse aggregate (right).

STUDY THE EFFECT OF POLYPROPYLENE FIBER IN

2016-9-4  Abstract - India leading developing country in world. In future high strength high performance concrete required for construction work.Fiber-reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. The character of fiber-reinforced concrete changes with varying concretes fiber materials, geometries, distribution, orientation, and densities. Polypropylene fiber is a light weight synthetic fiber. It prevents crack formation and provides reinforcement to the concrete structure. In this project work polypropylene fibers (Blended type) of different percentage (0.5%, 1%, 1.5%, and 2%) added in concrete.

Polypropylene fibre (PPF) is a kind of polymer material with light weight, high strength, and corrosion resistance. The crack resistance of concrete can be improved by adding PPFs. PPF can optimize the pore size distribution of concrete. As a result, the durability of concrete is significantly enhanced since PPF can block the penetration of water or harmful ions in concrete.
