Mangalore Tile Waste As Coarse Aggregate In Concrete

Mangalore Tile Waste As Coarse Aggregate In Concrete

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.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.

Utilisation Of Iron Ore Tailings As Aggregates In Concrete

Utilisation Of Iron Ore Tailings As Aggregates 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.Use of Iron ore dust in concrete M as an alternative to normal aggregates. Conclusion. Clay tile chips can be used in concrete as a satisfactory aggregate to obtain good quality concrete and give strength. Replacing crushed stone aggregate (CSA) with clay tile chip aggregate (TCA) yielded a 7th day compressive strength of up to 14.2 N mm2.
