CEM II – Portland composite cement: This comprises of seven types which contain clinker and up to 35% of another single constituent. i. Portland slag cement (CEM II/A-S and CEM II/B-S): This comprises of clinker and blast furnace slag which originates from the rapid cooling of slag obtained by smelting iron ore in a blast furnace. The ...

The compressive strength for concrete grade M20 (1:1.5:3) were investigated for the control mix and while cement was partially replaced by Iron fillings. The result of. The tensile strength of concrete is one of the basic and important properties which greatly affect the extend and size of the cracking in structures.

Co., Ltd., and Jingyou Sand Co., Ltd., respectively. IOT, clay, limestone, quartz sand, and iron ore were used as raw materials for Portland cement clinker production. Two di erent kinds of alumina-silicate material (clay and IOT) were used in the experiment. e calcareous material was limestone. Quartz sand and iron ore were used as corrective

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.

The most common raw rock types used in cement production are: Limestone (supplies the bulk of the lime) Clay, marl or shale (supplies the bulk of the silica, alumina and ferric oxide) Other supplementary materials such as sand, fly ash/pulverised fuel ash (PFA), …

raw materials (Iron ore, silica sand, gypsum and pozzolana are brought from nearby places. Limestone provides calcium oxide and some of the other oxides, while shale and the other materials (silica sand, iron ore) provide most of the silicon, aluminum and iron oxides required for the manufacturing of Portland cement.

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 and steel making slag are by products of the iron making and steelmaking processes. To date, these types of slag have been widely used in cement and as aggregate for civil works. The report presents an investigation of mechanical and durability properties of concrete by adding iron slag as replacement of sand in various percentages.

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.

Also, major problems caused by industrial waste in Nigeria can be minimised by recycling or re-using of such wastes for soil improvement. The application of cement and lime along for such purpose has proven to increase the construction cost. Thus the use of industrial waste such as iron ore tailings (IOT) could aid in reducing the construction ...

Abstract: Iron ore tailing (IOT) is a waste product of Iron Ore after manufacture, the wastes are environmental unfriendly as it poses serious problem of disposal, but can be used as a replacement in concrete mixture. The aim of this research is to

The pipeline coating material used in this study is the concrete made of 60% iron ore, 20% cement, 14% sand and water. Components of the concrete coating material were mixed in correct proportion and poured in a constructed mould to form 2 cm x 1 cm x 1 cm coupons of the concrete material. They were allowed to set for 24 hours. The
