Enhancement of the properties of silicate activated ultrafine-slag based geopolymer mortar using retarder

Application of high-volume slag based geopolymer mortar is often confined to usage in controlled environments due to its limited flexibility in controlling the setting time. The main aim of the study is to regulate the fast setting of Ultrafine blast furnace slag (UBFS)-based geopolymer mortar (GM) by utilizing mineral admixture. UBFS, partially replaced by Flyash (FA), are investigated by both sodium hydroxide (SH), and a combined solution of...
