Characterisation of recycled aggregate concrete through x-ray mapping

Every year, urban development generates large volumes of solid waste due to the construction and demolition. Most of the waste from construction becomes landfilled; however, as the population grows continuously, land demand soon becomes a shortage. Therefore landfill is no longer a suitable option to deal with construction waste. Over the last decades, many researches have been carried out on the usage of recycled coarse aggregate. These researchers are primarily focused on the possibility of using recycled concrete aggregate (RCA) as a replacement for natural aggregate [1, 2]. RCA is produced by the crushing of original concrete, it is usually either fully or partially used in the recycled aggregate concrete (RAC) [3]. The use of recycled aggregate in concrete opens a whole new range of possibilities in the reuse of the waste materials
