Abstract. Recycled aggregate concrete is a new technology for using a developed type of concrete that combines technicality with the environmental and recycling aspect. It is based on the reuse of old demolished concrete in the format of new aggregates for new concrete. The main advantage of this concrete is the reuse of construction debris which is a huge management problem in addition to complying with countries' requirements for recycling rates. This technology will also solve the problem of shortage of natural resources from which many countries suffer. Thus, this new technology is at the forefront of research and improvement studies in order to identify the technical characteristics: Mechanical properties, formulation, durability ... of a new concrete based on these aggregates. Morocco, as a developing country, favors the promotion of new technologies. It is true that the Moroccan standardization does not specify recycled aggregates but the use is more and more common in the last decade mainly in road works. The structural elements of the building require further study in order to technically validate the choice of concrete.
