Influence of the active additives on the structure and properties of expanded-clay lightweight concrete / Aktyviųjų priedų poveikis keramzitbetonio struktūrai ir savybėms

Vaičienė, Marija 19 January 2012 (has links)
Two active mineral additives were selected in the investigation described in the dissertation: unground catalyst from the reactor of catalytic oil cracking (CAT) and unburned mullite wool (MW). The possibilities to utilise these raw materials in the production of the expanded-clay lightweight concrete are not analysed yet. Main topic of the research: influence of the active mineral additives (CAT and MW) on the main characteristics of the expanded-clay lightweight concrete. / Disertacijoje aprašytuose tyrimuose buvo pasirinkti du aktyvūs mineraliniai priedai: nemaltas katalizatorius iš katalitinio naftos krekingo reaktoriaus (KAT) ir nedegta mulitinė vata (MV). Galimybės šias atliekas naudoti keramzitbetonio gamyboje iki šiol netirtos. Pagrindinė tyrimo tematika – aktyviųjų mineralinių priedų (KAT ir MV) įtaka pagrindinėms keramzitbetonio charakteristikoms.
