Jun 08, 2021  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.

Fiber Reinforced Concrete Topic

May 31, 2021  Fiber-reinforced concrete (FRC) is concrete made primarily of hydraulic cements, aggregates, and discrete reinforcing fibers. Fibers suitable for reinforcing concrete have been produced from steel, glass, and organic polymers (synthetic fibers). Naturally occurring asbestos fibers and vegetable fibers, such as sisal and jute, are also used for reinforcement.

Properties of Fiber Reinforced Concrete (FRC) – Types ...

Fiber-reinforced concrete is used to overcome the difficulty of plain cement concrete which gives very low tensile strength, low ductility strength, and a little strength to cracking. Also in plain cement concrete is a chance of brittle fracture because of the propagation of micro-cracks present in the concrete that makes poor tensile strength.

The tensile strength of concrete is only one-tenth of the compressive strength of concrete. Cracks develop in the structure during load. Because of the addition of the fiber in concrete cracks forms at the same load but the structure won’t fall apart, it will be held together by these fibers. Let’s see a short Experiment on Normal Concrete ...
