The American Concrete Institute ACI, which in 1895 created the Committee 555 "Concrete with Recycled Materials", has published many researches about the performance and feasibility of recycled aggregates in concrete, with results that allow deducing the possibility of substituting natural aggregates for those obtained from the recycling of concrete demolished structures ACI 555R-04, 2004.
