A study on durability and strength properties of high strength concrete
Iron ore tailings (IOT) were acquired from Jindal in the Bellary district of Karnataka. Physical tests were performed in accordance with IS 2836 Parts 1 and 3 and revealed a SG of 2.58, a water absorption rate of 1.0 percent, and a fineness modulus of 2.98.IOT met the criteria of grading Zone II, according to IS: 383–2016 [15], based on the 8.1. Introduction. Hematite and magnetite iron ores are the most prominent raw materials for iron and steel production. Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO).Comminution and classification technologies of iron ore

properties of concrete produced. Iron ore tailings (IOTs) is a waste product generated from the production process of iron ore. In this study, IOTs is used as partial replacement for natural sand in the production of normal strength concrete. Samples of Iron ore tailings from two different mines in Kota Tinggi were collected.For example, the content of SiO 2 in phosphate tailings is 2.1, in contrast to the 75.23 in iron ore tailings. Even if there were all lead-zinc tailings or iron ore tailings, the variation content of SiO 2 is 15.50-69.92 in the lead-zinc tailings or 24.19-75.23 in the iron ore tailings.

Blast Furnace Slag an overview ScienceDirect Topics
10.2.2 Blast furnace slag. Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.Sustainable handling of iron ore tailings is of prime concern to all stakeholders who are into iron ore mining. This study seeks to add value to the tailings by utilising them as a replacement for aggregates in concrete. A concrete mix of grade 40 MPa was prepared in the laboratory with water–cement ratio of 0.5.Utilisation of iron ore tailings as aggregates in concrete
