Characterizing the interfacial zones of fly ash based alkali activated adhesives to various substrates
Wolfgang Wisniewski, Vilma Ducman
Izvirni znanstveni članek
Oznake: lepilo;elektrofiltrski pepel;ITZ;odtržna trdnost;odprti dostop;adhisive;fly ash;pull of test;open ccess;
Alkali Activated Materials (AAMs) are important potential substitutes for cement in many materials. The AAMs presented here are based on industrial ground granulated blast furnace slag (GGBFS) and fly ash (FA). They are tested for their suitability as adhesives for joining concrete, ceramic tiles, a ...

Microstructural characterization of alkali-activated composites of lightweight aggregates (LWAs) embedded in alkali-activated foam (AAF) matrices
Katja Traven, Wolfgang Wisniewski, Mark Češnovar, Vilma Ducman
Izvirni znanstveni članek
Oznake: alkalijsko aktivirani materiali/geopolimeri;lahki agregat;SEM;
Alkali-activated composites of lightweight aggregates (LWAs, with beneficial insulating properties) and alkali-activated foams (AAFs, higher added value products due to their production from waste materials at well below 100 ◦C) allow for the expectation of superior properties if a chemical bonding ...

Clay rich river sediments calcined into precursors for alkali activated materials
Lea Žibret, Wolfgang Wisniewski, Barbara Horvat, Mojca Božič, Boštjan Gregorc, Vilma Ducman
Izvirni znanstveni članek
Oznake: sedimenti;alkalijsko aktivirani materiali;lastnosti;sediments;alkali activated materials;properties;
Alkali activated materials (AAMs), a potential alternative to cement-based products or ceramics, can incorporate large amounts of currently landfilled aluminosilicate rich materials such as calcined clay-rich river sediments collected at hydropower plant dams. Untreated fresh sediment and untreated ...
