  • Blastfurnace Hybrid Cement with Waste Water Glass Activator: Alkali-Silica Reaction Study 

    Kalina, Lukáš; Bílek, Vlastimil; Bradová, Lada; Topolář, Libor (MDPI, 2020-08-17)
    Hybrid systems represent a new sustainable type of cement combining the properties of ordinary Portland cement and alkali-activated materials. In this study, a hybrid system based on blast furnace slag and Portland clinker ...
  • Correlating Hydration of Alkali-Activated Slag Modified by Organic Additives to the Evolution of Its Properties 

    Bílek, Vlastimil; Kalina, Lukáš; Dvořák, Richard; Novotný, Radoslav; Švec, Jiří; Másilko, Jiří; Šoukal, František (MDPI, 2023-02-25)
    This study investigates the relationships between the hydration kinetics of waterglass-activated slag and the development of its physical-mechanical properties, as well as its color change. To modify the calorimetric ...
  • Decalcification resistance of various alkaliactivated materials 

    Hrubý, Petr; Bílek, Vlastimil; Topolář, Libor; Kalina, Lukáš; Marko, Michal; Šoukal, František; Dvořák, Richard; Herčík, Tomáš (IOP Publishing, 2021-09-29)
    The resistance of alkali-activated materials (AAMs) to degradation processes, particularly the decalcification, was studied in this paper. The ground granulated blast furnace slag was alkali-activated using various activators ...
