Aggregates were at laboratory airdry condition. Waste copper slag from blast cleaning was used as a partial replacement of sand. Average chemical composition of the slag is as follows: SiO 2 30–45%, CaO 10–30%, Fe 2 O 3 <25%, Al 2 O 3 7–15%, MgO 2–8% and the granulation was much finer than in the case of typical river sand.

The Redcar and Davy Dry Slag Granulation Process (Great Britain) is analysed as the example of the dry granulation arrangement. Traditionally the liquid slag is atomized by high pressure water jets which impinge on the slag stream as it leaves the runner. The rapid cooling produces the glassy structure which is necessary for cement making. In Donetsk there is 300000 tonne of the molten blast ...

 · Dry granulation methods can be divided into three main areas: (1) mechanical granulation [11, 16], (2) centrifugal granulation [12, 16,17,18,19,20,21], and (3) air granulation. In mechanical dry granulation, molten slag is broken up and quenched via mechanical means such as rotating drums, blades, or shot materials. An example is the Paul Wurth mixing method, in which molten slag is mixed .
