2014-1-15 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 ...

2021-1-1 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 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.

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.

2021-9-4 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.
