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. Other characteristics of the IOT, as sand and cement replacements materials in concrete production exhibited improved workability and higher compressive strengths over the control strength with approximately 10 % and 38 % for sand and cement respectively. The linear regression models that were developed on the experimental data showed that they are significant and could be used to predict relationships of IOT-OPC concrete.
