04-03-2021· All the specimens with iron ore tailings replacement have higher compressive strength and less deterioration percentage than control. A higher resisting capacity of 60.3 MPa was observed for MBS2 specimens in which a moderate replacement of 30% iron ore tailings was used for fine aggregate.
Effect on compressive and tensile strength of cement concrete road pavements due to use of Iron ore tailings as replacement to fine aggregate Utilisation of iron ore tailings as aggregates in concrete Francis Atta Kuranchie 1*, Sanjay Kumar Shukla, Daryoush Habibi and Alireza Mohyeddin1 Abstract: Sustainable handling of iron ore tailings is of prime concern to all stakehold-ers who are into ...
Influence of Addition Contents of Iron Ore Tailings on Structural Mortar Nara Linhares Borges de Castro 1, ... Iron ore tailings consist mainly of the chemical elements Si, Fe and Al (Cancio et al., ... of natural aggregates for tailings, as reported by (Ugama & Ejeh, 2014).
EFFECT OF RED MUD AND IRON ORE TAILINGS ON THE STRENGTH OF SELF-COMPACTING CONCRETE Kiran K. Shetty Associate Professor (Senior Scale), Dept. of Civil Engineering, PhD, ... that the replacement of natural aggregate by Iron ore tailings significantly replaced the workability and compressive strength of material.
11-09-2020· Kumar et al. investigated the effect of partial/total replacement of sand by iron ore tailing, as the fine aggregate on the compressive and flexural strength of reinforced concrete. The compressive strength was increased by up to 40% with the replacement of sand by iron ore tailing, while there was an enhancement of flexural strength for all percentages of sand replacement (10%, 20%, 30%, 40%
Fig.1 Iron Ore Tailing of fine aggregate with IOT and bottom ash helps to effectively In India, over 70% of electricity generated is by ... To study the effect of iron ore tailings on the property of concrete when used as fine aggregate.
15-01-2014· 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 mechanical properties of UHPC.
Iron ore tailings have the potential to be used as fine aggregate because they are relatively inert and the particle sie 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
The mix with only sand as fine aggregate served as the control mix, while sand was replaced in the other mixes by 20%, 40%, 60%, 80% and iron ore tailing (IOT). Consistency and Strength test were conducted on both concrete specimens. It was observed that concrete workability reduced with increase in the percentage of iron ore tailing in ...
In this study, the effect of Iron Ore Tailings (JOT), as fine aggregate in mortars, on microstructure and compressive strength with 14 days was observed on mortar specimens.
Effect of iron ore tailings as fine aggregate on pore structure of mortars has been studied in this paper. The purpose is to investigate, as fine aggregate, comparing to natural sand, whether the iron ore tailings can improve the pore structures of mortars or not. Pore structure parameters were measured with the instrument of MIP and calculated with corollary software.

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water ...
Iron ore tailing: Iron ore tailing has collected in Lakhya dam which is generated by Kudremukh Iron Ore Company Limited. Properties of iron ore tailing has found out. IOT has specific gravity of 3.16, pH of 9.56, electrical conductivity of 141 S/cm and it has the total dissolved solids 88.9 mg/l.
iron ore tailing (IOT) as fine aggregate would turn this waste material into valuable resources, reduction in the strain on the supply of natural sand, and economy in concrete production. World production averages one billion metric tons of raw ore annually.

23-05-2020· Iron ore tailings. A number of representative iron ore tailing samples were acquired from different locations of the dry tailing disposal areas (cf. Fig. 2).As illustrated in Fig. 3, the tailings were loosely dumped as piles; thus, their sampling did not necessitate any particular practice and merely involved filling bags with a hand shovel.
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. The KIOCL company which was a leading company in India in the mining activities of iron ore has dumped about 200 million metric tons of iron ore ...
