Slag Cement Lehigh Hanson, Inc.

The iron is used to produce steel, and the molten slag is converted to a cement-like material by rapidly cooling it with water. This rapid cooling, called quenching, creates glassy granules, which are then ground into the fine powder known as slag cement. Slag cement is as old as iron-making itself.

Slag Cement Questions Slag Cement Association

Slag cement is the hydraulic cement that results when molton slag from an iron blast furnace is rapidly quenched with water, dried and ground to a fine powder. The rapid quenching ("granulation") "freezes" slag cement in a glassy state and imparts cementitious properties to the product when ground finely.

Discoloration — What, why, & how? Nevada Ready Mix

CSurface discoloration is the non-uniformity of color or hue on the surface of a single concrete placement. It may take the form of dark blotches or mottled discoloration on flatwork surfaces, gross color changes in large areas of concrete caused by a change in the concrete mix, or light patches of discoloration caused by efflorescence.

Ground granulated blast-furnace slag Wikipedia

Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing
