In this investigation, it was aimed to improve the properties of concrete blocks partially made with recycled aggregates from construction and demolition waste (RCD), for which, it was incorporated the use of 3 additions along its elaboration process: plasticizer, diatomite and cement remover. The waste was obtained from a multifamily housing project in Lima and was collected in the pre-construction process, so it includes waste from concrete pouring, pieces of joists and waste from the concrete cutting. The waste residues were manually crushed to get the size required and were tested according to Peruvian regulations. Then, with the characteristics of the aggregates obtained, the mixture design was elaborated by the ACI method for 5 mixtures considering a replacement of 35% of recycled aggregate and the use of the 3 selected additions, including as well, a mixture without additions and a mixture only with natural aggregates for its use as a point of comparison. To measure the mixtures efficiency, the compressive strength of the blocks was measured, and the results were compared with the standards NTP 399.602 and E.070. As well as that, an economic and environmental analysis was developed for the blocks made and for those offered in the current Peruvian market. The results obtained guarantee the approval of the mixtures with diatomite and cement remover, as they achieved better properties than the base mixture. In addition, even though the use of cement remover obtained greater compressive strength values, the diatomite was found to be the best option because of its cost/profit ratio compared to other mixtures.
