  • 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 ...
  • 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 ...
  • Fracture properties of concrete specimens made from alkali activated binders. 

    Šimonová, Hana; Kucharczyková, Barbara; Topolář, Libor; Bílek, Vlastimil; Keršner, Zbyněk (IOP Publishing, 2017-09-15)
    The aim of this paper is to quantify crack initiation and other fracture properties – effective fracture toughness and specific fracture energy – of two types of concrete with an alkali activated binder. The beam specimens ...
  • Influence of alkali-activated materials placement during curing on their dynamic parameters 

    Plšková, Iveta; Matysík, Michal; Topolář, Libor; Bílek, Vlastimil (EDP Sciences, 2020-04-16)
    The production of Portland cement has a considerable environmental impact. Its replacement with alkali-activated binders can contribute to reducing the environmental burden of building production. The paper presents partial ...
