Synthetic aggregates may be either byproducts of an industrial process, in the case of blast-furnace slag, or products of processes developed to manufacture aggregates with special properties, as in the case of expanded clay, shale, or slate used for lightweight aggregates. Some lightweight aggregates such as pumice or scoria also occur naturally.

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.

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.

The most commonly used lightweight aggregate comprises expanded clay, slag or shale for primary use in structural concrete and expanded perlite or vermiculite for primary use in insulating concrete. Mixtures of the two general types of aggregates are sometimes used to obtain a desired strength, bulk density of thermal conductivity.
