Mine (Iron ore, Copper and Manganese ore) tailings are industrial waste material obtained in the mines, after the extraction of concentration from the ore. Some percentage trace of ore properties will be left in the ore waste after the extraction process is completed, known as tailings. These ore tailings which are produced in large quantity in the ore mines, which is unfit for farming and makes the land barren. Disposing of this tailing from the mines premises is a big head ache for the concerned authorities. The use of any industrial waste in construction acts as an environmental friendly project. These industrial wastes always cause pollution and their disposal is a problem for the concerned authorities, because either they occupy lot of space for their storage or they pollute the media in which they are discharged. In this experimental work, an attempt has been made to study the suitability of ore tailings in the preparation of building blocks by stabilizing it through cement. Different percentages of cement are being used for the stabilization. Dry compressive strength, wet compressive strength, moisture absorption and erosion resistance were found out on the prepared specimens. The results show that the stabilized building blocks of mine ore tailings with 7% addition of cement and 7% cement with extra percentage of sand show the maximum compressive strength with advantage in other properties.
