  • 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 ...
  • The FBC ash as a hydraulic ingredient of hydraulic lime 

    Dvořák, Karel; Kulísek, Karel; Gazdič, Dominik (Elsevier, 2017-01-31)
    This work is focused on the possibilities of utilization of ashes from fluidized bed combustion, i.e. FBC ashes, for the manufacturing of hydraulic lime. Alternative hydraulic binders are becoming very popular in the present ...
  • Flexure response of thermal loaded concrete specimens by acoustic emission method 

    Pazdera, Luboš; Topolář, Libor; Mikulášek, Karel; Smutný, Jaroslav; Hoduláková, Michaela; Chobola, Zdeněk; Seelmann, Herbert (EDP Sciences – Web of Conferences, 2017-05-24)
    The response to fire of concrete structural members depends on the thermal, mechanical, and deformation properties of concrete. These properties vary significantly with temperature depending on the composition and ...
  • 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 ...
  • Raw materials for mullite grog manufacturing 

    Nevřivová, Lenka (IOP Publishing, 2018-07-07)
    The primary condition for manufacturing is the correct choice of raw material, a suitable treatment facility, and a kiln capable of firing at temperatures above 1400 °C. This paper assesses some local raw materials for ...
  • The microstructure of a cement composite based on a secondary raw materials 

    Figala, Petr; Drochytka, Rostislav (IOP Publishing, 2018-07-16)
    Waste management and its use as a secondary raw material is a matter that is being given increasing attention. Such raw materials also include waste products from the energy industry or municipal waste disposed of from the ...
  • Mortars with crystalline additive in aggressive environments 

    Žižková, Nikol; Nevřivová, Lenka; Lédl, Matěj; Keprdová, Šárka (IOP Publishing, 2018-07-16)
    The paper describes how a crystalline additive influences the properties of cementbased composites. The investigation was focused on the degradation of mortars with crystalline additive exposed to selected aggressive ...
