  • Recycled Concrete aggregate attrition during mixing new Concrete
    Construction and Building Materials, 2016
    Co-Authors: Jaime Moreno Juez, Bogdan Cazacliu, Alexis Cothenet, Riccardo Artoni, Nicolas Roquet
    Abstract:

    In this work, the Recycled Concrete aggregate (RCA) friability during mixing was studied in order to better understand the evolution of this material during the mixing process and improve the Recycled aggregate Concrete mix-design. The influence of some important materials and process parameters was evaluated: initial abrasion resistance and initial moisture of the aggregates, mixer geometry, mixing time and mixing speed. To assess the mixing process effect on the Recycled Concrete aggregate friability, three different aspects were evaluated; the mass loss (mass of fraction inferior to 2.5 mm) the grading and the angularity evolutions with mixing time of an initially 10-14 mm aggregate. Tests were carried out in two types of laboratory Concrete mixers, a planetary 30 l mixer from Skako and an intensive 5 l Erich mixer. The results revealed that in normal laboratory setting of the mixers configuration, the mass loss for natural aggregate (NA) is less than 1% of the coarse aggregate. This percentage reach 3% for good quality Recycled Concrete aggregate (MDE value of 21) and 5% for lower quality Recycled Concrete aggregate (MDE value of 27). The mass loss directly depends on the mixing parameters and the degradation of the Recycled Concrete aggregate drastically increased when the mixing speed was raised to 500 RPM. By analyzing the grading evolution during mixing, it was shown that both cleavage (creation of intermediate size particles) and attrition (creation of small particles) mechanisms influenced the aggregate degradation. However, the configuration of mixing significantly influenced the proportion of attrition and cleavage mechanisms. To complete this work, the angularity evolution showed that Recycled Concrete aggregate surface becomes smoother and the edges more rounded after mixing.
