Synthetic macro fiber is a type of polymer fiber, also known as polypropylene imitation steel fiber, Polypropylene macro fibers, or composite fiber. Since the mid-19th century, it has been widely researched and promoted, and has become a re...

Fiber reinforced concrete is a composite material composed of Portland cement, aggregates, and fibers. Ordinary unreinforced concrete is brittle and has lower tensile strength and strain capacity. The role of randomly distributed irregular...

The addition of polypropylene fibers to concrete has no significant effect on the compressive strength and elastic modulus of concrete, but it does increase the tensile strength of concrete. The splitting tensile strength of fly ash concret...
