Utilization of iron ore tailings as fine aggregate in ...
Jan 15, 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 stone 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.
Evaluation of iron ore tailings as replacement for fine ...
Zhang et al. also investigated properties of concrete with iron ore tailings and manufactured sand as fine aggregate. They reported that the drying shrinkage of mixed sand is less than river sand concrete and with increase in IOT the drying shrinkage of mixed sand decreases.
The Influences of Iron Ore Tailings as Fine Aggregate on ...
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.

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 ...
Using Iron Ore Tailings in Concrete | Browns Paving and ...
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 4.75 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.
Experimental Study on the Properties of Concrete Mixed ...
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. In addition, iron ore tailings have higher water absorption than natural sand.
