Interaction enhancement between recycled PET macro-fiber reinforcement and cement matrix via plasma treatment

Popis výsledku v původním jazyce

Presented work deals with an interaction enhancement between recycled PET macro-fibers reinforcement and cement matrix via plasma treatment (oxygen low-pressure inductively coupled plasma). Wettability between demineralized water/treated fibers and adhesion between fibers/cement matrix were studied in order to assess the treatment effect. The wettability was measured using an optical goniometer, while the adhesion was examined by means of indirect mechanical testing - displacement controlled four-point bending tests of cement samples reinforced with reference and 30 s treated fibers. Consequently, an impact of the treatment on fiber tensile strength was tested. It was shown, that the plasma modification increased the fiber wettability by the water almost three-times already after 5 s treatment, while fiber tensile strength stayed almost unaffected. Bending tests revealed that the prismatic cement samples reinforced with treated fibers reached to higher toughness in elastic response, to higher residual-strength in post-cracking phase and to lower maximal limit of elasticity in comparison with reference samples.
