Advances in Recycled Aggregate Concrete

Wang, Yu

Abstract

The construction industry produces about 1183 million metric tons of construction and demolition wastes each year worldwide, in which concrete waste takes the most considerable proportion. The disposal of such huge quantities of waste has become an enormous burden to landfill capacity and environment. Recycling this waste and using it in new construction has been regarded as a viable solution for the sake of sustainable development.

However, as a substitute resource for virgin raw materials, deep knowledge of how the use of recycled aggregates influences the final concrete properties is still very limited, particularly considering that the recycled aggregates have wide uncertainty and variability in quality. How do their inherited faults in microstructure and purity influence the hydration process and bond with paste matrix? How do advanced improving technologies work in scientific mechanisms, etc.? To promote communication of the knowledge and research in material science on the topic, we have planned this Special Issue and are inviting worldwide researchers to contribute their original research work, case investigations, reviews of research development, and advances in the research area.
