Municipal solid waste incineration bottom ash as an admixture for magnesium-based cement composites with expanded perlite: Technical properties and heavy metal immobilization

Zbyšek Pavlík, Martina Záleská, Milena Pavlíková, Adam Pivák et autres

This study investigated the incorporation of municipal solid waste incineration bottom ash (MSWIBA) into magnesium potassium phosphate cement (MKPC) composites and evaluated the effect of expanded perlite on their properties and heavy metal immobilization. MSWIBA was added at 10–20 wt.%, while expanded …

Formation of Graphene Agglomerates in MOC and Their Negative Influence on Material Properties

Anna-Marie Lauermannová, Adéla Jiříčková, Michal Lojka, Martina Záleská et autres

, confirming preservation of quasi-brittle behavior. The novelty lies in the integrated multiscale approach (XRD, SEM-EDS, MIP, XCT, CMOD), enabling quantitative differentiation of graphene agglomerates from air voids and direct structure-performance correlation. The results establish graphene dosage limits in MOC and demonstrate …
