Cement. Production of granulated blast furnace slag is used to make Ecocem, a superior slag cement ideal for underwater applications.. Slag Cement Slag is a by-product of iron and steel making. In nature, the ores of metals are found in impure states, often oxidized and mixed in with silicates or other metals.
soils. Blast furnace slag concrete can be reliably pumped when the slag is supplied to the ready-mix production in a saturated condition. Use of the cementatious properties of ground granulated blast furnace (GGBF) slag was reported as early as 1774. GGBF slag has been used in concrete in Japan and Western Europe since the 1940s. Concrete ...
Iron and steel slag products are used in a variety of areas where their unique characteristics are put to effective use. The majority of the demand for these products comes from the field of cement. Approximately 40% of iron and steel slag products, and 60% of blast furnace slag, are used in cement.
