Investigation of usability of quarry dust waste in fly ash-based geopolymer adhesive mortar production

Crushed-stone dust is a harmful waste product of crushed-stone aggregate concrete production. It has no added value and is disposed of by washing in well-organized facilities. This study experimentally investigated the geopolymer-based adhesive mortar in order to use crushed-stone dust as a building material at the best rates. Fly ash (FA) was used as the geopolymer binder and sodium silicate (SS) and NaOH were used as alkali activators. NaOH...
