This research analyzes the results of the incorporation of aggregates from CDW, and their incorporation into a new mixture with virgin aggregates, as well as their projection to propose the formula that can predict their behavior in case of intending to use higher percentages in a new concrete mixture. The natural aggregate was substituted in percentages of 0%, 30% and 60% when the coarse aggregate was replaced and 0%, 25%, 50% when the fine aggregate was replaced. The base data taken for this article come from the result of two investigations carried out in the Civil Engineering laboratories of the Universidad Privada del Valle, La Paz academic headquarters, which allow their analysis and projection for higher percentages of CDW.
