Evaluation of the Iron Ore Tailings from Itakpe in Nigeria ...

Mar 04, 2014  An evaluation of the Itakpe iron ore tailings (IOT) for concrete production has been carried out using the material to replace sand and cement, in proportions of 5 % up to 30 %, and curing for periods 90 days in water. Characterization of the material showed that it has pozzolanic properties, and can be used as a retarder for hot-weather concreting.

Properties of Concrete

Portland cement is produced by mixing ground limestone, clay or shale, sand and iron ore. This mixture is heated in a rotary kiln to temperatures as high as 1,600 degrees Celsius. The heating process causes the materials to break down and recombine into new compounds that can react with water in a crystallization process called hydration.
