ismail and al-hashmi  studied the effect of waste iron as a partial replacement of sand in concrete. a 130 kg of waste iron were reused to partially replace sand at 10% 15% and 20% in a
at the edge of the iron smelting pit a gigantic clawed hand emerges from the red hot pool. mr. x isn't down for good yet and he may be more dangerous than ever. claire runs out to the monitor room. a motion detector alerts her that someone else is in the lab. leon is onscreen emerging from the power room.
experimental study of concrete made with granite and iron powders as partial replacement of sand. they highlight the advantages of using such recycled materials in concrete because of potential cost regulatory and green certification benefits. their results showed comparable results between the concrete with iron ore tailing less than
recycling of steel scrap reduces the need for iron ore extraction significantly reducing co2 emissions energy and water consumption and air pollution. however the critical limiting factor is the availability of sufficient steel scrap as much steel remains locked in its current use (such as in durables automobiles and
reuse of iron ore mineral wastes in civil engineering constructions: a study. from the particle size analysis it was found that grain sizes of 12.5–20 mm are suitable for use in concrete which means approximately 50–60% by volume of total waste is consumed. fine aggregates between 12.5 and 4.75 mm can be used as sand for various
the objective of this study is to evaluate the modified performance of concrete with mixing of iron ore tailings in order to solve the shortage of natural sand and make full use of industrial waste. firstly the raw materials of mixing were analyzed and the test ratio was determined. secondly the workability and mechanical property of concrete specimens with different amounts of iron ore
