Concrete Reinforced with Polypropylene Fibers Concrete ...

Jun 01, 1983  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

For concrete reinforced with a single fiber, the polypropylene fiber gave rise to a more adverse effect on the compressive strength than carbon fiber at the same volume fraction. This can be correlated with the higher elastic modulus and tensile strength of the carbon fiber, which is of greater efficiency in restraining the transverse deformation.
