“…The selection of aggregate is significant, and their quality assumes an incredible job; they can restrict the strength of concrete well as attributable to their attributes, they influence the toughness and execution of cement [6]. The overall utilization of sand as fine aggregates (FA) in concrete production is high, and a few non-industrial nations have experienced some strain in the flexibility of normal sand to meet the expanding needs of infrastructural advancement as of late [7]. Thus, there is an enormous interest in elective materials for fine aggregates in the development business.…”

The world is pounding with millions of tons of industrial wastes such as ground granulated blast furnace slag (GGBS), fly ash, and mine tailings as various industrial wastes. The best way to make use of these wastes is to incorporate these materials as structural elements, which in turn minimizes the carbon footprint. In this context, this study focuses on using iron ore tailings and slag sand as a replacement for clay or natural sand for the production of stabilized blast furnace iron slag brick. Also, in this study sand is used as a stabilizer instead of more clay ratio. The development of sand-based bricks using fly ash and ground granulated blast furnace slag has been carried out in this research. The study includes the mechanical properties of the slag iron bricks. Sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) solutions have been used as alkaline activators. The ratio of alkaline liquid to alumina-silicate concrete ratio and the percentage of the binder had a major influence on the strength of the brick. The bricks were cast and cured at ambient temperature. Compressive strength at 7, 14, and 28 days and the thermal conduction analysis are the major experimental works including some of the minor findings like water absorption, density and other tests were carried out.
