    • MECHANICAL PROPERTIES IMPROVEMENT OF FIBER REINFORCED CONCRETE 

      Author: Trejbal, Jan; Nežerka, Václav; Hlůžek, Radim; Prošek, Zdeněk
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Fiber reinforced concrete mechanical properties are limited due to low adhesion between polymer fibers and cement matrix. To ensure a strong interaction between the two materials, polypropylene fibers (d = 0.305mm) were ...

    • RECYCLING OF CONSTRUCTION WASTE USING HIGH-SPEED MILLING PROCESS: DETERMINATION OF WASTE CONCRETE 

      Author: Prošek, Zdeněk; Tesárek, Pavel; Trejbal, Jan; Horová, Tereza
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      This paper deals with the use of high-speed milling process for recycling old concrete and direct determination of the potential of input waste. For this purpose, three different types of waste concrete were used: prefabricated ...

    • SHORT-TERM CORROSION RESPONSE OF METALS IN LIME MORTAR 

      Author: Bauerová, Pavla; Prošek, Zdeněk; Krejsová, Jitka; Keppert, Martin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
      Even though the corrosion of steel in concrete is very well described, the corrosion processes in lime environment studied very rarely. This environment is obviously also basic and its pH decreases in time, but the obtained ...
