Nickel Slag Air-cooled nickel slag is brownish-black in color. It crushes to angular particles but has a smooth, glassy texture. The specific gravity of air-cooled nickel slag may be as high as 3.5 (15), while the absorption is quite low (0.37 percent). (3) The unit weight of nickel slag is somewhat higher than that of conventional aggregate.

vi. Expanded or ed Slag: Expanded slag is one of the most important types of light weight aggregates. The blast furnance slag is a by-product of the manufacture of pig iron. The expanded or ed slag is produced by rapidly quenching blast furnance slag. The quenching of slag can be done by the following two methods: (a) Water jet process.

Most lightweight aggregate is produced from materials such as clay, shale, or slate. Blast furnace slag, natural pumice, vermiculite, and perlite can be used as substitutes, however. To produce lightweight aggregate, the raw material (excluding pumice) is expanded to about twice the original volume of the raw material.

Using such by-products for lightweight aggregate production is a feasible way in recycling of waste materials. Manufacturing artificial lightweight aggregates can be achieved by cold bonding, autoclaving or sintering procedures [1, 2, 5–7, 11, 19]. Some LWAs produced by crushing expanded clay, slates or shale have irregular shapes.
