The first blast furnace slag cement was produced in Germany, in 1800, by mixing slag and lime [6]. Even before 1800, however, the properties of such cement were studied in France. Since the 1860s, it has been used in commercial production, and in the United States, slag .
Free calcium and magnesium oxides are not completely consumed in the steel slag, and there is general agreement in the technical literature that the hydration of unslaked lime and magnesia in contact with moisture is largely responsible for the expansive nature of most steel slags.(1,2) The free lime hydrates rapidly and can cause large volume ...
To Improve Soil Quality in Acid Soils Soil pH is an excellent chemical indicator of soil quality. Farmers can improve the soil quality of acid soils by to adjust pH to the levels needed by the crop to be grown. Benefits of include increased nutrient availability, improved soil structure, and increased rates of infiltration.
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
