Improving Effect of Mineral Admixtures on Volume Stability of Steel Slag Mortar LUN Yunxiaa, ZHOU Mingkai b , CAI Xiao c Key Laboratory of Silicate Materials Science and Engineering of Ministry of Education, Wuhan University of Technology, Wuhan, 430070, China.
Every year nearly 50 million tons of steel slag is generated, but the utilization rate is only 10% in civil engineering in China [1].
However, the excellent physical and mechanical properties of BOF slag has been reported as a promise materials for potential use in civil engineering as aggregates [6-9].
Undissolved free MgO coming from flux containing dolomite and from MgO refractory used as the lining of the steel furnace is another major factor for the utilization in civil enginnering [11].
