It is possible to improve the properties of the BBA via mechanical processes (like screening or fotation) to reduce the organic matter content and there by obtain processed BBA (Pr-BBA). This study provides interesting data on the mechanical and durability properties of the concretes manufactured with 30% aiRCA and aiRMA, and also by applying diferent replacement rates (0, 15, and 30%) of NA by BBA and Pr-BBA. The mechanical and durability properties were analysed over diferent time durations in diferent mixtures. It was dem- onstrated that it is possible to apply these recycled mate- rials in non-structural concrete mixtures by limiting the replacement rate. The application of BBA and Pr-BBA reduced the properties of the concrete. However, this reduc- tion was less signifcant with the use of Pr-BBA. Abstract Recycled aggregates (RA) have been exten- sively studied in the production of concrete. Normally, the coarse fraction of recycled concrete aggregates (RCA) is the most commonly used to manufacture recycled con- cretes. The manufacturing of concrete with fne fraction of RCA and/or recycled mixed aggregates (RMA) (from a mix of concrete, asphalt, masonry, etc.) has not been studied in depth. In most cases, the recycling plants produce RA with an ALL-IN particle size distribution. These recycled materials could be named as ALL-IN RECYCLED CON- CRETE AGGREGATES (aiRCA) and ALL-IN RECY- CLED MIXED AGGREGATES (aiRMA). Applying these aiRCA or aiRMA, limiting the percentage of the substitu- tion of natural aggregates (NA) by the aiRCA, is more ben- efcial for both the production costs and the environment. In recent studies, other by-products, such as biomass bottom ash (BBA) were used in concretes, substituting natural sand * F.
