Abstract

The purpose of this study reutilization of waste fine tailing (FT) as admixture for cement and concrete. Various admixtures were made of Fine tailings and 2 Types of OPC, fly-ash and blast furnace slag. Cement mortars and concrete with FT are tested for fluidity and compressive strength. Also, the hydration reactivity of cement mortar with FT was examined by XRD and SEM morphology analysis. This work showed that the waste fine tailing could be effectively utilized as replacement materials of cement without any decrease in the strength if we can control the blaine of materials like cement, blast furnace slag and fly ash.
