A Review on Feasibility Study on The Use of Iron Ore Tailings as a Fine Aggregates with Glass Fiber in Concrete

Abstract

Concrete, a fundamental construction material, forms the basis for infrastructure projects globally. The environmental impact of concrete is influenced by factors such as the type of concrete and the quantity of cement used. Cement, a key component of concrete, has diverse effects on the environment. Additionally, the surge in concrete demand necessitates vast amounts of natural river sand, a crucial fine aggregate in concrete production. This heightened demand leads to adverse effects on river ecosystems, including increased riverbed distance, lower water tables, exposure of bridge substructures, and substantial impacts on rivers, deltas, coasts, and marine environments. The scarcity of natural river sand elevates its cost, underscoring the necessity for affordable raw materials. To address the need for cost-effective alternatives, attention turns to iron ore tailings (IOT), a byproduct from the iron concentrates beneficiation process. Combining IOT with glass fiber in concrete emerges as a strategy to enhance its properties. This overview discusses research conducted on the utilization of iron ore and glass fiber as partial replacements for fine aggregates, examining their impacts on the workability, durability, and mechanical properties of concrete.
