The present investigation was carried out at Private University of Trujillo, the compressive strength of recycled concrete samples with controlled parameters was determined. This research explains the influence of the percentage and maximum nominal size of recycled concrete as a substituent of the coarse aggregate, on the compressive strength of a recycled concrete; based on a Type I portland cement. The percentages of recycled concrete added were 0%, 10%, 20%, 30%, 40% and 50%, for maximum nominal sizes of the coarse aggregate, and using a water / cement ratio of 0.56 with a design resistance of 210 kg / cm3. The mix design was elaborated based on the characterization of the concrete materials according to method ACI 211, in fresh condition for the concrete: the unit weight test was carried out according to ASTM C 138, concrete density (expressed in kg / cm3 ), then 36 test pieces (15 cm in diameter and 30 cm in height) were prepared and subjected to curing by immersion in water for 28 days according to ASTM C 31, then in hardened state for the recycled concrete: the test was carried out compressive strength according to ASTM C 39 for the determination of the load that will support this concrete (expressed in kg / cm2), the problem is that in the city of Trujillo there are large dumps of concrete which are not reused due to the ignorance of the parameters of these materials. Regarding the results of this research, it was found that 30% recycled concrete can be used, and it was determined that the properties of this concrete are from 283.79 kg/cm2 to 281.74 kg/cm2 which implies a reduction of less 5% with respect to traditional concrete (standard test tube 0%).
