for iron ore as a number of steel plants have been planned for future in many parts of the country. In order to reduce the adverse impact of indiscriminate mining of natural sand, iron ore tailings which is the waste products of mining industries is used as an alternative to the river sand in the manufacturing of concrete.

Iron ore tailings (IOT), the predominant solid by-products of iron ore mining and refining, present significant environmental challenges due to their sheer volume. This paper endeavors to scrutinize the prospective deployment of IOT as an alternative to soft soil in the fabrication of controlled low strength materials (CLSM) for backfill applications.

Abstract. In this study, the potential of converting iron ore tailings (IOTs) into sustainable building materials was explored. IOTs were combined with fly ash (FA) and ground granulated blast-furnace slag (GGBFS) to prepare IOTs-based supplementary cementitious materials (SCMs). A concrete mix using IOTs-aggregate was also …

ABSTRACT- Pavement stabilization using iron ore waste is a technique for improving the strength and durability of road surfaces. The process involves mixing iron ore tailings, …

A concrete mix containing 25% iron ore tailings gives higher compressive strength than the reference concrete . The results indicate that concrete workability decreased with a rise in the content of iron ore tailing-alccofine and that the average compressive strength was 70, 68.67, and 65Mpa at 40%, 30%, and 20%.

As examples of previous studies with the same purpose, we can mention the reviews on steel slag (Martins 2021), iron ore tailings (Zhao et al. 2021), waste glass (Mohajerani et al. 2017, plastic ...

Steel slag (SS) is a kind of industrial solid waste, and its accumulation brings certain harm to the ecological environment. In order to promote the building material utilization of SS, high ...

However, the current reclaiming ratio of waste steel in China is still low due to lack of advanced slag treatment equipment and technology. 3.1.2. Utilization as sinter material Steel slag with CaO content above 50% can be used as sinter ore fluxing agent, partially replacing the commercial lime.

Due to exponential growing in urbanization and industrialization, byproducts from industries are becoming an increasing concern for recycling and waste management. Ground granulated blast furnace slag (GGBS) is by-product from the blast-furnaces of iron and steel industries. GGBS is very useful in the design and development of high-quality …

Utilization of Industrial Waste in Concrete Mixes—A Review. Rajwinder Singh, Vaibhav Chaturvedi, Ankit Kumar Chaurasiya & Mahesh Patel. Conference paper. …

The amendment of cementitious binders with waste materials aids as a path to reduce the volume of waste and carbon emission. This review summarizes the current state of practice for cementitious binder fabrication in favor to the utilization of waste materials such as waste concrete powder (WCP), coal bottom ash (CBA) and steel …
