The iron ore tailings aggregates concrete exhibited a good mechanical strength and even in the case of compressive strength, there was an improvement of ... The aim of this paper is to study the feasibility of using the iron ore tailings as both fine and coarse
iron ore tailings. Their flex-compression ratio was 1/6 and 10 % higher than that of the control group that used sand as the fine aggregate. The crack resistance of the iron ore tailings concrete was studied at the same time, and the microstructure was observed with an SEM.
Key words: iron ore tailings; size distribution of granules; compressive strength Abstract: Innovative researches on properties of sand grout with iron ore tailings (IOT) as fine aggregate were conducted. The results show that exclusive ferrous mineral in the IOT is merrihueite beside quartz in both IOT and nature sand (NS).
Iron ore tailings have the potential to be used as fine aggregate because they are relatively inert and the particle size of the tailings is significantly larger than that of cement. This paper investigated the use of iron ore tailings to replace natural sand as fine aggregate and studied the impact that various replacement levels had on the ...
Title: Characterization of Iron Ore Tailings as Fine Aggregate Author(s): Sikiru Folahan Oritola, Abdul Latif Saleh, and Abdul Rahman Mohd Sam Publication: Materials Journal Volume: 117 Issue: 2 Appears on pages(s): 125-134 Keywords: concrete-making material; fine aggregate; iron ore tailings; microscopy of material; sustainability; waste material Date: 3/1/2020
In this paper, the possibility of using iron ore tailings to replace natural aggregate to prepare UHPC under two different curing regimes was investigated. It was found that 100% replacement of natural aggregate by the tailings significantly decreased the workability .
As shown in Figure 3, the slumps and liquidity of concrete mixed with iron ore tailings decreased compared with that of normal concrete under the same condition (water, mixture ratio, admixture, etc.).This phenomenon arises because the particles of iron ore tailings are rough and occluded with coarse aggregate, so cohesion increases significantly in the tailing mixes.
Jan 01, 2020· Iron ore tailings (IOT) are the by-products of iron ore beneficiation, and these tailings are disposed of in several tons annually in quarries, landfills, and tailings dams, causing environmental issues. Various researchers have attempted to study the properties of IOT and the use of them in concrete as a building material.

In this study, finely powdered waste glass from industries and Iron Ore Tailings (IOT) produced from mining areas are used as a partial replacement of cement and fine aggregates in concrete respectively. This work examines the possibility of using Glass powder and iron ore tailing as a partial replacement of cement and fine aggregate in concrete.
The constituent materials were batched by weight. The mix with only river sand (RS) as fine aggregate served as the control mix, while sand was replaced in the other mixes by 20%, 40%, 60%, 80 % and 100 % iron ore tailing (IOT). It was observed that the Iron or tailing contain more fines passing BS number 200 sieve than the river sand used.
Iron Ore Tailings As Fine Aggregate Nepal. Iron ore tailings were added to the experimental concrete along with the cement the tailings were split up according to particle size those that were 475 mm in diameter and below were used as fine aggregates and those that were 10 to 20 mm in diameter were used as coarse aggregates.

Iron Ore Crushing Production Line,Iron Ore Crusher, . The iron ore dressing and crushing production line has the features of high automation, low operation cost, fine particle size, energy saving and environment protection.
Iron Ore Waste As Coarse Aggregate In Concrete. Utilization of mine waste rocks and tailings in concrete as aggregates will help in sustainable and greener development the literature shows the potential use of iron ore tailings as a replacement of natural fine aggregates as natural sand reserves are d epleting day by day there is a need for substitution for sand in concrete
One of the largest No-Sulfur IRON ORE reserves in the Western Hemisphere of over 18,200 Acres – Copper – Titanium – Vanadium & Silica Sand. " Between 47 and 59 billion tons of aggregate material consisting mostly of sand and gravel is mined every year (2010), and .

The present study looks for the feasibility of preparing UHPC with iron ore tailings (IOT for short) as fine aggregate. To enhance outstanding high performances, some influences on UHPC mortars were investigated such as different kinds of sands, different mix ratio of sands, and different largest particle size of fine aggregate. The results show that IOT have negligible poorer aggregate ...
Notable among the alternatives are to use iron ore tailing to manufacture bricks, ceramic tiles (Das et al. 2012), as fine aggregate in mortar, and coarse aggregate in concrete (Huang et al. 2013 ...
