The main objective of this research work was to determine the effects of bronze residues, as a substitute for fine aggregate, on the properties of fresh and hardened concrete. The bronze residue used was that produced in the manufacture of keys that was obtained from some people who perform the trade in the Trujillo district; in the search to be able to use this material within concrete, as part of the construction sector that has been growing this year, and to find some technical benefit that may contribute to proposing other uses of this waste and thus contribute to the care of the environment. To meet our objective, concrete mix designs were made based on a standard concrete following the ACI 211 methodology for concrete with resistance f´c = 210 and 280 kg / cm2. Specimens of 100 x 200 mm were made, some for standard concrete (normal design) and other specimens where the fine aggregate was replaced by percentages of bronze residues (5, 10 and 15% respectively), considering a plastic consistency of 3 ""- 4"". The data obtained in the compression resistance test with the specimens, were statistically analyzed and it was determined that the substitution by bronze residues in replacement of the fine aggregate in the formation of the concrete, causes it to decrease its resistance in a range of percentage of 5 to 10% of its compressive strength as this addition increases. This bronze residue (mineral addition) when chemically contacting the calcium hydroxide of the cement, contributes by reducing the compressive strength; however, they have been found to maintain workability.
