    Článek prezentuje laboratorní výzkum zaměřený na posouzení vlastností a mikrostruktury cementotřískových desek modifikovaných alternativními surovinami. Konkrétně bylo modifikováno složení pojiva jemně mletým vápencem a ...

  • Long-term durability of cement-bonded particleboards with modified composition by waste dust 

    Melichar, Tomáš; Bydžovský, Jiří; Dufka, Amos (CEMC - České ekologické manažerské centrum, 2021-12-01)
    This paper presents research on long-term behaviour of cement-bonded particleboards exposed to adverse conditions. The boards were subjected to frosting / defrosting cycles, up to 300 cycles. Specifically, 100, 200, 300 ...

  • Immobilization of Heavy Metals in Natural Zeolite-blended Cement Pastes 

    Vyšvařil, Martin; Bayer, Patrik (Elsevier, 2016-09-26)
    This paper deals with the investigation of efficiency of natural zeolite-blended cement pastes for the immobilization of heavy metals. Natural zeolite was used to partially replace ordinary Portland cement (OPC) at rates ...

  • Wear of grinding rotors with thermally-sprayed coatings in a high-speed mill 

    Tkachenko, Serhii; Dvořák, Karel; Jech, David; Slámečka, Karel; Klakurková, Lenka; Paloušek, David; Čelko, Ladislav (Elsevier, 2018-10-15)
    In this paper, the erosion behavior of three types of protective thermally-sprayed coatings and non-coated substrate steel was investigated under semi-industrial test conditions using a laboratory high-speed pin mill DESI-11. ...

  • The Effect of the Wear of Rotor Pins on Grinding Efficiency in a High-speed Disintegrator 

    Dvořák, Karel; Dolák, Dušan; Paloušek, David; Čelko, Ladislav; Jech, David (Kaunas University of Technology, 2018-02-19)
    One of the directions intensively investigated in the field of milling is high-energy milling (HEM). One type of HEM is high-speed grinding in high-speed disintegrators. This type of mill is particularly suitable for the ...

  • Composites Based on Alternative Raw Materials at High Temperature Conditions 

    Melichar, Tomáš; Bydžovský, Jiří; Dufka, Amos (Budapest University of Technology and Economics, 2017-10-24)
    This paper presents newly developed polymer-cement composites. The primary binder (cement) was partially substituted by use of blast-furnace slag and high-temperature fly ash. A lightweight aggregate – agloporite (grain ...

  • Effect of firing temperature on the structure of the aggregate from sintered ashes 

    Černý, Vít; Tůmová, Eva (Elsevier, 2016-08-03)
    Production of artificial aggregate from ashes is worldwide known technology that uses up to 100% of ash in the mixture. There are known two types of aggregate. First is based on binders and known as cold-bonded. Second ...
