PE Fiber, also known as Polyethylene Fiber, is a synthetic fiber that is added to concrete to improve its performance. It is an alternative to traditional reinforcement materials such as steel and is becoming increasingly popular due to its numerous benefits and advantages.
The addition of PE fibers can reduce the drying shrinkage of cementitious materials. More than 10% reduction of the drying shrinkage of cementitious materials was witnessed. The crack width and crack area decreased with the content of PE fibers.
