WitrynaOptimum fiber volume content has been addressed by many researchers. Civil engineering concretes typically are reinforced with <5 vol.-% of steel, glass, natural or synthetic polymer fibers [42]. Fiber contents greater than 2–3 vol.-% result in poor workability and fiber dispersion within the concrete mix [27,44]. WitrynaUHMWPE is a type of polyolefin that is composed of very long chains of polyethylene with a very high percentage of parallel orientation and high level of crystallinity. The extremely long polymer chains enable load transfer by strengthening intermolecular interactions. UHMWPE fibers are manufactured in a gel spinning process. …
