How Cement Is Made

How Cement Is Made

Portland cement is the basic ingredient of concrete Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients

Evaluation of the Iron Ore Tailings from Itakpe in Nigeria ,

Evaluation of the Iron Ore Tailings from Itakpe in Nigeria ,

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
