slag

[slag]
(metallurgy)
A nonmetallic product resulting from the interaction of flux and impurities in the smelting and refining of metals. Also known as bloom.

slag

A grayish aggregate left as a residue of blast furnaces; used as surfacing on built-up roofing and in manufactured products such as slag cement and slag wool. Also see blast-furnace slag.

slag

1. the fused material formed during the smelting or refining of metals by combining the flux with gangue, impurities in the metal, etc. It usually consists of a mixture of silicates with calcium, phosphorus, sulphur, etc.

The structures of the slags were also detected by FT-IR spectroscopy (Nicolet 5DXC).
ions are electrically driven into the pore network, leading to an increased charge transfer during the test, so the fact that Figure 6(b) shows a lower charge passed value for alkali-activated slags than the Portland cement reference can be taken to indicate that the actual chloride movement through the materials is likely to be much slower.

The application of steel slag from steel mills was not very popular until the late 1990s, for there were vast amounts of blast-furnace steel slag available, while the steel slag from steel mills was used for the manufacture of chemical fertilizers, where only the so-called Thomas steel slag, a by-product of steel production from phosphorous raw iron, was used.
