Apr 09, 2020· MELBOURNE, AUSTRALIA, APRIL 9, 2020 --Researchers have shown how a by-product of steel making can be used to both treat wastewater and make stronger concrete, in a zero-waste approach to help advance the circular economy.Produced during the separation of molten steel from impurities, steel slag is often used as a substitute aggregate material for making concrete.
Slag contains reusable lime and metallic scrap that can be reused, in addition, being able to completely recycle it will save on cost of fuel, dumping, and transportation. The company STEIN Injection Technology developed a way to separate lime for the scrap and convert it in to usable wire injection that can once more be used to create clean steel.
At 28 days, concrete mixture containing 1% hook end steel fibre and 80% copper slag displayed optimum compressive strength of 44.25 MPa against 31.04 MPa of control concrete. At 7, 28 and 56 days, compressive strength of concrete mixture made with copper slag was 32.64, 26.71 and 24.71% higher than that of reference concrete, respectively.
