Description
Summary:	Construction and demolition waste (RCD), due to its properties can be reused in the preparation of concrete, however, in most cases this is not used, giving it an inadequate management and final disposal, which has led to it being they present numerous environmental and social problems. Taking this reality into account, this study is proposed, which aims to evaluate the compressive strength of a concrete with the substitution of construction and demolition waste as coarse aggregate, for which the collection of the waste that corresponds to this case was carried out. to pavement residues, then the material was washed and crushed to a size of ¾ ”and, later, five designs of mixtures were made with different RCD replacement ratios, as well as the standard sample, and then to each of the The designs were subjected to the compression test at 7, 14 and 28 days. Among the results, it was found that the mix design that had the highest resistance to compression was the one that had a proportion of 75% replacement of RCD and 25% of natural coarse aggregate with a result of 4604 psi at 28 days, in addition Regarding the standard sample, this obtained its highest resistance at 28 days with 5416 psi; Likewise, it was evidenced that as the days go by, the concrete improves its resistance
