Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expan-sion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling (Figs. 1 and 2)..of sand making operation in Nouakchott

Usually, about 70 kilograms of pebble-sized burnt lime is added per ton of steel early in the blow; this combines with silica and other oxides to form about 150 kilograms of slag per ton of steel. Adding burnt dolomite (CaO MgO) results in a magnesia (MgO) content in the slag of about 6 percent, thereby decreasing slag corrosion of the magnesite lining.

It also increases the depth of hardening due to quenching, but at the same time also decreases the solubility of carbon in iron at high temperatures. This would decrease its usefulness in making blister steel (cementation), where the speed and amount of carbon absorption is the overriding consideration. The addition of phosphorus has a down side.
