بيت /light weight aggregate or waste are suitable for crushing
States. As most CDW concerns inert waste, the major product from recycling is recycled aggregates. An important use of recycled aggregates is in road construction, for which they are very suitable. Other applications are also highlighted in this factsheet. As an example, this factsheet describes the approach and situation in The Netherlands.

demonstrated that waste plastics can be beneficially incorporated in concrete, it is important to observe that not all waste materials are suitable for such use [Zanaib et al, 2008]. The research reported in this paper is focused on the assessment of the viability of secondary plastics as aggregates for concretes.

PCAs which have low crushing values will not be crushed as easily as the stone aggregates. These aggregates are also lighter in weight compared to stone aggregates. Since a complete substitution for NCA was not found feasible, a partial substitution with various percentage of PCA was done.

The production of lightweight aggregates is a promising way to valorise these wastes. In the development of a suitable process the main disadvantage is borate migration towards the surface of the green pellets that causes excessive liquid phase formation during firing and subsequent sticking of the aggregates together or with the refractory lining of the kiln.

Sand sludge is a waste product from crushing and screening plants for sand and gravel production. Preliminary studies demonstrate the feasibility of recycling sand sludge into lightweight aggregates. The properties of lightweight aggregates from sand sludge depend on both, the preliminary firing temperature of the frit and the ing temperature of the green granules.
