Recycled aggregate (RA) has been used in various construction applications around the world, mainly as sub-grade, roadwork and unbound materials, but not in high-grade applications. This paper examines relationships among demolished concrete (DC) characteristics, properties of their RA and strength of their recycled aggregate concrete (RAC).

Closed-loop recycling of recycled concrete aggregates
Journal of Cleaner Production, 2012Reduce, reuse and recycle for environment recovery and respect are the key principles of a sustainable construction material. Much research has been conducted regarding the use of recycled concrete aggregates (RCA) in concrete mixes recycled from parent concrete of natural source aggregates, referred here as first generation.

Durability of Recycled Aggregate Concrete
2014Recycled aggregates (RA) are now well-known to be suitable for structural concrete production. The employment of RA (obtained from concrete or ceramic waste) in recycled aggregate concrete (RAC) production as a structural material has been widely analysed and validated in many applications.

Critical Analysis of Recycled Aggregate and Concrete with Recycled Aggregate
Applied Mechanics and Materials, 2011One of the construction sector's major contributions to the preservation of the Environment and sustainable development is the reuse and recycling of the waste materials it generates (reducing, reusing, recycling and regenerating the residues that originate the constructive activity).

Properties of recycled aggregate and recycled aggregate concrete: effect of parent concrete
Asian Journal of Civil Engineering, 2018In the present investigation, an attempt was made to study the influence of the strength of parent concrete on the properties of recycled aggregates and recycled aggregate concrete. In this study, four grades of normal concrete mixes: M20, M25, M30, and M40 were considered as parent concrete to produce the recycled coarse aggregates and recycled ...

Durability of recycled aggregate concrete
Construction and Building Materials, 2013Abstract This paper presents the main results of the research carried out to analyse the physical, mechanical and durability properties of concrete incorporating recycled aggregate. One of the most unknown aspects of recycled aggregate concretes is related to their durability in aggressive environments.

Modeled Recycled Aggregate Concrete
2017Based on the microstructure analysis, recycled aggregate concrete (RAC) can be described as a five-phase composite that consists of natural aggregates (NA), old interfacial transition zone (old ITZ), old mortar, new interfacial transition zone (new ITZ) and new mortar.

Recycled concrete—a new aggregate
Canadian Journal of Civil Engineering, 1978Large urban centres in Canada and the United States are finding it increasingly difficult to locate and develop natural aggregate sources for use in concrete. The study reported herein was therefore undertaken to investigate the possibility of producing aggregates from discarded concrete control test cylinders, normally sent to waste dumps after ...
