Effect of carbonation on recycled concrete aggregates microstructure by Neutron and X-ray tomography
Recycled concrete aggregates carbonation is one of the key solutions proposed since the last decade to trap the emitted CO2 back into the concrete, and to approach carbon-neutrality. This is a complex process, and depends on several factors, such as the CO2 transport within the material, the moisture content in the pore network and other environmental conditions. However, their effects are still poorly understood, and all current theories rely on point-wise, macroscopic measures, neglecting the intrinsically heterogeneous nature of the process. We seek instead, using the complementary of X-ray and Neutron tomography techniques, to quantify, in-situ, the spatio-temporal evolution of CO2 absorption and moisture profiles during carbonation over a range of conditions to understand the micro-scale processes underlying the macroscopic response. The uniquely high flux available will allow for testing the efficiency of the carbonation process over a matrix of conditions, which will bolster the ongoing development of improved numerical models.
