Experimental Study on the Properties of Concrete Mixed ...
A series of laboratory experiments on the mechanical behavior of concrete prepared by abandoned iron ore tailings in Iraq was carried out by Ismail and AL-Hashmi , and results revealed that its performance was superior to ordinary concrete and exhibited higher compressive strength and flexural strength.
Flexural behaviour of reinforced iron ore tailings ...
Flexural behaviour of reinforced iron ore tailings concrete (IOTC) beams There is a need for alternative material for sand as fine aggregate in concrete. This study, therefore looks at the feasibility of using iron ore tailings (IOTs) as partial replacement for sand to produce reinforced concrete beams.
Compressive and flexural strengths of concrete with iron ...
The DOE method was used in designing the concrete mix for the concrete and then modified to replace 10 %, 20 % and 40 % of the sand by iron ore. The study was conducted in laboratory to investigate the behavior of the concrete in term of mechanical strength as well as the physical properties.

Utilization of iron ore tailings as fine aggregate in ...
Jan 15, 2014 · Iron ore tailings are a common type of hazardous solid waste in China and have caused serious environmental problems, and the high cost of producing ultra-high performance concrete (UHPC) provides the motivation to look for low-priced raw materials.
Evaluation of iron ore tailings as replacement for fine ...
Millions of tons of iron ore tailings (IOT); a by-product of iron ore processing, are disposed of every year in landfills, quarries, rivers, oceans among others thereby posing environmental problems. The major aim of this study is to evaluate IOT as replacement for river sand in concrete and compare with the result of conventional concrete.

Iron Ore Tailings (IOT) is one of the materials that is considered as a waste material which could have a promising future in construction industry as partial or full replacement of fine aggregates.
Effect of red mud addition on the corrosion parameters of ...
This behavior may be due to three isolated factors or to their combination: i) increasing alkalinity in the region near the steel-concrete interface; and/or ii) greater anchoring of chloride ions due to the presence of sodium aluminosilicates, which prevent the free movement of these ions and make them unavailable to start the corrosion process, as discussed with respect to the results of the chloride migration test; …

Cement Products Suppliers & Distributors - CEMEX USA
Cement is a fine powder, obtained from the calcination at 1,450°C of a mix of limestone, clay, and iron ore. The product of the calcination process is clinker—the main ingredient of cement—that is finely ground with gypsum and other stone additives to produce cement. Cement is the most widely used construction material worldwide.
Effect of Replacing Sand by Iron Ore Tailings on the ...
• The sand in cement concrete may be replaced by iron ore tailing in concrete production without compromising on the strength and it greatly reduces the water and land pollution that would otherwise occur due to disposal of the iron ore tailing on land.
