Concrete contains up to 80 volume percentage of aggregates which forces producers to use extensively available local resources to avoid very high transportation costs and related carbon dioxide emissions. In addition, many regions around the world face increasing problems to obtain good quality natural aggregates and the only alternative is to use various types of wastes, industrial by products or recycled concrete. If application of these types of aggregates in normal concretes is rather common, the situation is quite different in the case of the self-compacting concrete.

This chapter will focus on reviewing current Stata of the art on utilization of aggregates produced from wastes and industrial by products. A number of currently available waste streams are described and their potential for application in self-compacting concrete is evaluated. Effects on fresh and hardened concrete properties are described. In addition, basic physical properties and durability aspects are addressed as well.
