The mix with only sand as fine aggregate served as the control mix, while sand was replaced in the other mixes by 20 , 40 , 60 , 80 and 100 iron ore tailing (IOT). Consistency and Strength test were conducted on both concrete specimens. It was observed that concrete workability reduced with increase in the percentage of iron ore tailing in.Variation laws of cement stabilized iron tailings sand mixtures loss of water, dry shrinkage strain and temperature shrinkage coefficient have been obtained by the indoor shrinkage test, which are compared with cement stabilized gravel. Results of test show that its dry shrinkage strain are greater than cement stabilized gravel. There is no significant difference of temperature shrinkage.

The Iron Ore Tailings (IOT’s) a waste product, with particle size range from (850μm - 75μm) obtained from Iron Ore Processing was utilized as fine aggregate to produce concrete. Based on British Standard (BS) guidelines, normal concrete mix was designed. Five types of concrete samples (C0, C1, C2, C3, and C4) were produced, with the.2. The limestone is combined with clay, iron ore and sand. It is then ground in a crusher and fed into. 3. Next, the fine powder is heated as it passes through the Pre-Heater Tower into a large kiln. In the kiln, the powder is heated to 1500oC. This creates a new product, called clinker, which resembles pellets about the size of marbles.

Portland cement manufacturing is an energy intensive process in which cement is made by grinding and heating a mixture of raw materials such as limestone, clay, sand, and iron ore in a rotary kiln. The kiln is a large furnace that is fueled by coal, oil, gas, coke and or various waste materials.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.
