Performance of recycled aggregate concrete based on a new concrete recycling technology
Construction and Building Materials, 2015Abstract One of the main environmental challenges in the construction industry is a strong social force to decrease the bulk transport of the building materials in urban environments. Considering this fact, applying more in-situ recycling technologies for Construction and Demolition Waste (CDW) is an urgent need.

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.

Recycled concrete as an aggregate for concrete—a review
Matériaux et Constructions, 1978The present state of knowledge on the use of recycled concrete as an aggregate in new concrete is reviewed and suggestions made as to what further work is necessary before a proper assessment of the material can be made. Where crushed uncontaminated concrete is used the properties of the material as an aggregate and the basic engineering ...

THE USE OF RECYCLED CONCRETE FILLERS IN CONCRETE
Mechanics and Technologiesfine recycled concrete aggregates (fRCA), the current state is discussed, attention is paid to their physical, chemical and engineering properties, as well as the strength of fRCA concrete. Without further research, it is impossible to draw conclusions about the recommendations and tools for the widespread use of fRCA in new concretes, while ...

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 ...

Recycling of Demolished Concrete
"SP-200: Fifth CANMET/ACI Conference on Recent Advances in Concrete Technology-Proceeding, Fifth International Conference", 2001In Japan, it has been predicted that enormous quantities of demolished concrete will be produced in the future. Therefore, a great deal of research is being conducted to find ways to recycle this demolished concrete as concrete aggregate. However, because the characteristics of the original concrete are not well known in many cases, the results are ...

There are obstacles to the use of Recycled Aggregates in Ready-Mix Concrete (RMC), one of them being the need of additional silos, often impossible for plants in urban areas, while it is in these areas that recycled aggregates are mostly available. Another main issue is the control of moisture in the aggregates and the impact on fresh concrete rheology.

Recycled Materials in Concrete
2013This chapter examines the use and production of concrete incorporating end of life materials from other processes. These “end of life” materials were once termed waste products and many have the ability to improve the properties of concrete by their addition.
