The aim of this paper is to study the feasibility of using the iron ore tailings as both fine and coarse 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.

investigation on the Iron ore tailing based interlocking paver blocks and experimental values shown that 5 to15% usage of iron ore tailing increases the compressive strength than conventional concrete. Shetima et al. 15 carried out the study on the replacement fine aggregate by iron ore tailing. In the present study Iron Ore Tailings (IOT) procured from Kudremukh Lakya Dam site (KIOCL Ltd.) are used as partial replacement to fine aggregates at levels of 10, 20,30,40,50 percent and the basic material properties, strength parameters are studied. It is found that as the IOT percentage increases in the mix workability is reduced.

The increasing annual emissions of iron ore tailings have proved a great threat to the natural environment, and the shortage of natural river sand, as well as the pursuit of sustainable development materials, provides motivation to reuse iron ore tailings as a fine aggregate in concrete. 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 ...

Jan 21, 2021 The iron ore concentrate has commercial value as such and, therefore, was considered no further in this study. The IOT sand was used as replacement for the conventional fine aggregates (particles smaller than 300 m) in the production of the HTs. The IOT clay was used in the production of pigments to replace the conventional ones. 2. Fine aggregate Two types of fine aggregates are used a) Steel slag as received from the factory without any screening b) Silica sand of natural resources known locally as desert sand. Sieve analysis was carried out on both the natural sand and the fine slag according to ASTM C33.Specific gravity and

Sep 04, 2021 Shettima et al. stated that the use of waste iron ore as fine aggregate reduces the workability of concrete but increases its strength. Fluorite is an important industrial mineral composed of calcium and fluorine (CaF 2) found in many parts of the world. Fluorite can be formed in magmatic, metamorphic and sedimentary rocks. Fine aggregates are the particles that pass through 4.75 mm sieve and retain on 0.075 mm sieve. Coarse aggregates are the particles that retain on 4.75 mm sieve. 3 Materials Sand, surki, stone screenings, burnt clays, cinders, fly ash, etc are used as fine aggregate in concrete.
