This research, carried out in the city of Trujillo, evaluated how the partial replacement of natural coarse aggregate with coarse aggregate obtained from recycled concrete affects the properties of the concrete both in the fresh state, such as unit weight and slump, and in the hardened state, with the properties mechanical and durability. The main objective is to determine the influence of the percentage replacement of recycled aggregate on the aforementioned properties. Today we find in Peru a low development in terms of the culture of debris recycling, especially so-called construction and demolition waste. As an example we have the life cycle of the natural aggregate, whose administration does not contemplate its recycling, which makes construction an unsustainable industry and whose efforts are not oriented toward environmental benefit. The little information regarding the durability properties and the study of this branch of construction in our country drives research such as this one, which seeks to establish a starting point by determining an optimal replacement percentage. The procedure included the acquisition of raw materials for the preparation of concrete: Portland cement type Ico, ½" TMN natural coarse aggregate, fine aggregate, water, SikaCem plasticizing admixture and specimens used to be crushed and converted into recycled coarse aggregate. Then, the mix design was carried out according to ACI 211, adjusting the water content and adding plasticizer. The replacement percentages used were 0% (standard specimen), 15%, 25% and 35% with respect to the total mass of natural aggregate in the original design. The study was carried out with a one-factor experimental design and probabilistic sampling, using observation guides for data collection. After evaluating the manufactured concrete through tests such as: unit weight of concrete in the fresh state, slump test, compressive strength, content of acid-soluble chlorides in the concrete, it was concluded that the replacement of up to 35% of the coarse aggregate by recycled concrete does not significantly compromise the behavior in the evaluated tests, remaining within the values allowed by the respective technical standards.
