Worldwide research has shown that there exist clear differences between properties of recycled coarse aggregates (RCA) and those of natural coarse aggregates (NCA), such as porosity, water absorption, low surface density, higher crush value. According to the specific performance requirements of concrete, choosing appropriate raw materials, then ...

Self-compacting concrete using recycled asphalt pavement and recycled concrete aggregate
Journal of Building Engineering, 2017Abstract In this study recycled concrete aggregate (RCA) and recycled asphalt pavement (RAP) are used in the production of self-consolidating concrete (SCC) with varying percentage replacements of natural coarse aggregate (NCA). A total of 16 concrete mixtures were prepared and tested.

Cement and Concrete Composites, 2005
Abstract The subject of concrete recycling is regarded as very important in the general attempt for sustainable development in our times. In a parallel manner, it is directly connected with (a) increase of demolition structures past out of performance time, (b) demand for new structures and (c) results––especially in Greece––of destruction by natural

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.

Developing geopolymer concrete using fine recycled concrete powder and recycled aggregates
Magazine of Concrete ResearchTo develop a sustainable geopolymer concrete (GC), the efficacy of using fine recycled concrete powder (FRCP) and recycled aggregates (RA) as partial replacements for fly ash (FA) and natural aggregates (NA), respectively, was investigated. The compressive strengths of different GCs were measured.

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.
