Název v původním jazyce

Fiber Reinforced Concrete: Residual Flexure Strength Enhancement Using Surface Modified Fibers

Popis výsledku v původním jazyce

Fiber reinforced concrete often fails due to poor adhesion between polymer fibers and the cement matrix which is caused by fiber flat and chemically inert surfaces. Such a phenomenon can be overcome by modifying the fibers with plasma treatment which activate and roughen their surfaces. Polypropylene-polyethylene and polypropylene macro-fibers were exposed to low-pressure cold dioxygen plasma treatment for 30 seconds. In order to quantify how plasma treated fibers can affect mechanical response of fiber reinforced concrete, notched specimens containing 0.75 vol. % of reinforcement were made and subjected to three-point bending test. It was shown that specimens with modified fibers exhibited up to 40 % improvement in residual flexural tensile strength than those containing reference reinforcement.
