Overview of durability properties of recycled aggregate concrete
Use of recycled aggregate concrete (RAC) for structural purposes is still limited in spite of extensive research projects that have been done worldwide. The reasons are impurities in recycled aggregates, lower density and higher water absorption in comparison to natural aggregates that influence on concrete mechanical and durability properties. Only in EU, there is around 850 million tons of construction and demolition (C&D) waste per year. It is estimated that approximately 90 % of C&D waste could be reused or recycled, depending on the structure and local market of waste materials. Researchers identified various influencing aspects related to the use of recycled aggregates, such as replacement level, size and origin, as well as the influence of curing conditions, use of chemical and mineral admixtures on carbonation, resistance to chloride ion penetration, freeze-thaw resistance, capillary water absorption and water permeability. This paper gives overview of durability properties of RAC produced with different amounts of recycled concrete aggregate.
