  • Fracture parameters of concrete after exposure to high temperatures: pilot tests 

    Šimonová, Hana; Halfar, Petr; Rozsypalová, Iva; Daněk, Petr; Keršner, Zbyněk (EDP Sciences, 2017-05-24)
    Experimental concrete panels were after an appropriate aging time loaded by high temperatures (550, 600, 800 and 1000 °C) in a furnace intended for fire tests of building materials. These panels were heated according to ...
  • Influence of freeze-thaw cycles on fracture parameters values of lightweight concrete 

    Kucharczyková, Barbara; Keršner, Zbyněk; Pospíchal, Ondřej; Misák, Petr; Vymazal, Tomáš (Elsevier Ltd., 2010-06-06)
    Freezing and thawing resistance is very important characteristic also in the case of lightweight concrete. The paper deals with the influence of periodic freeze-thaw cycles on lightweight concrete fracture parameters values. ...
