    • PERFORMANCE OF CEMENT COMPOSITES REINFORCED WITH SURFACE-MODIFIED POLYPROPYLENE MICRO- AND MACRO-FIBERS 

      Autor: Antoš, Jakub; Dejdar, Lukáš; Trejbal, Jan; Prošek, Zdeněk
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      This paper focuses on the mechanical properties investigation of cement pastes reinforced with surface treated polymer fibers. The cement matrix was composed of Portland cement (CEM I 42.5 R, w/c ratio equal to 0.4). Two ...

    • PLASMA TREATMENT IMPACT ON PHYSICAL AND CHEMICAL PROPERTIES OF POLYMERIC FIBERS 

      Autor: Hlůžek, Radim; Prošek, Zdeněk; Trejbal, Jan; Fládr, Josef; Potocký, Štepán
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      Presented work focuses on chemical and physical properties of plasma modified polymeric macro-fibers. Polyethylene terephthalate (PET) and polypropylene (PP) fibers having approx. 300 μm in diameter were modified using ...

    • PULLOUT BEHAVIOR OF OXYGEN PLASMA TREATED POLYMER FIBERS FROM CEMENT MATRIX 

      Autor: Trejbal, Jan; Horová, Tereza; Prošek, Zdeněk
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      The aim of this work is to describe bonding properties between surface treated polymer fibers and a cement matrix. In order to increase an interaction between the matrix and fiber surfaces, two fiber types having approx. ...
