This thesis investigates utilizing iron ore mine waste and tailings as aggregates in concrete pavements. Concrete mixes were developed with partial replacement of coarse aggregates with iron ore waste rock (WR) and partial replacement of fine aggregates with iron ore tailings (IOT) at different percentages. Concrete properties such as compressive strength, flexural strength, …
Solid waste management is a critical issue worldwide. Effectively utilizing these solid waste resources presents a viable solution. This study focuses on Iron ore tailings (IOTs), a solid waste generated during iron ore processing, which can be used as supplementary cementitious materials (SCMs) but have low reactivity, hindering their large-scale application …

Normal strength concrete was designed based on water/cement ratio of 0.54 and cement content of 463Kg/m3 was used in preparing the fresh concrete. For each kind of Iron ore tailings concrete, four different types of concrete samples were produced.
Regarding particle sizes, there are three types of IOT categories: iron tailings rock, produced by mechanical crushing of lowgrade ore and wall rock, with a granulometry above 4.75 mm and used as ...
Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate [7], and have been used by many researchers as a replacement for fine aggregate in concrete production [8][9][10][11], [12][13]–[16] This paper is about the review of various research works on the nature of IOT and its effects ...
It was found that the iron ore tailings may be utilised for complete replacement for conventional aggregates in concrete. The iron ore tailings aggregates concrete exhibited a good mechanical strength and even in the case of compressive strength, there was an improvement of 11.56% over conventional aggregates concrete.
Particularly, iron ore tailings (IOT) as ordinary industrial solid waste in China is discharged and deposited. This review is a recapitulation of the material characteristics of IOT …
The aim of this research is to test the characteristics of concrete by substitute fine aggregate with iron ore tailings and partial glass powder as in the place of cement.
Millions of tons of iron ore tailings (IOT); a by-product of iron ore processing, are disposed of every year in landfills, quarries, rivers, oceans among others thereby posing environmental problems.
After the beneficiation of iron ore, the waste is generated, which arise many environmental issues for both living and nonliving components. Iron ore tailings are a byproduct of the mining and processing of iron ore, and their potential use as a replacement resource is the emphasis of this study.
