Abstract


In this study, the tail ore was be used as a fine aggregate of RPC or gelled material, because it is rich of silicon and its particle size is peculiar. Through choosing the raw materials reasonably, optimizing the water/cement ratio, water reducing agent dosage and mineral admixture content, the economical RPC was be prepared with tail sand instead of the grinding fine quartz sand, mixing different properties of mineral admixtures.
