Research into more effective use of blast furnace slag and LD slag
Different LD slags from LD or OBM steel-works with a free lime content ranging from 0% to more than 10% were subjected to tests on industrial ageing (6m high slagheaps) for one year. At regular intervals, samples were taken and subjected to swelling tests in laboratory conditions in water at 80 C. It was shown that ageing without artificial means (sprinkling etc) is not sufficiently effective inside the heap. The results of this research do not call into question the 4.5% lime content limit previously adopted in order to make LD slag usable for road construction. The swelling test in water at 80 C is simple and reproducible.
