· The current review aims to summarize the studies conducted during the past decade on geopolymers containing quarry dust and mine tailings. The first section discusses various precursors used for geopolymer cement production such as metakaolin, ground granulated blast furnace slag (GGBFS), fly ash, and quarry/mining ore wastes

Quarry Rock Dust can be defined as residue, tailing or other non-voluble waste material after the extraction and processing of rocks to form fine particles less than 4.75mm. Usually, Quarry Rock Dust is used in large scale in the highways as a surface finishing material and also used for manufacturing of hollow blocks and lightweight concrete prefabricated

· Abstract. Iron ore tailing (IOT) is the wastes generated during the salutariness process of iron ore concentration. These wastes are abundant in quantity, which can be utilized in many ways. In this manuscript, utilization potential of IOT as a resource and its adaptation in the replacement of different industrial raw materials have been

· Quarry tailings are usually stockpiled due to stable crystalline structures below 100 C and abundant sources, which lead to a serious environmental impacts and high ecological risks. This paper presents a study of transforming the fly ash and quarry tailings as the main raw materials into lightweight aggregates (LWAs) for using in civil engineering.
