Peru is a country where solid waste management is underestimated; few regions provide adequate management of solid waste. This is evident in the La Libertad Region, where deficient collection, handling, and treatment of solid waste are easily noticeable. The cityscape often reflects a significant presence of construction waste, particularly in its outskirts, highlighting the pressing need for intervention. Therefore, this research focuses on evaluating a concrete with f´c=210 kg/cm² using a superplasticizer additive, replacing 15%, 30%, and 45% of coarse aggregate with construction debris in the city of Trujillo, employing an experimental methodology. The study involved testing the physical properties of the aggregates (gradation, moisture content, unit weight, and specific gravity) as well as the Los Angeles Abrasion test to assess the wear of natural aggregates and construction debris as a mechanical property. Additionally, tests were conducted on fresh concrete (unit weight, temperature, and slump) and the compression test according to the specifications of various Peruvian Technical Standards (NTP). The results showed that for a 15% replacement, the 28-day strength was 248.81 kg/cm², for 30% it was 246.83 kg/cm², and for 45% it was 243.68 kg/cm², which were 2.30%, 3.10%, and 4.34% lower than the strength obtained with the standard concrete (254.68 kg/cm²). It is concluded that construction debris is a viable alternative as a substitute for coarse aggregate when using a superplasticizer additive, as the mechanical properties remain stable for all substitutions performed, although the strength gradually decreases as the percentage of substitution increases
