Resumen

The purpose of the current research was to determine the compressive strength of concrete cores with iron, aluminum and copper metal chips replacing 10% of the fine aggregate. The study has a experimental design character, with a total of 72 samples, which were divided into standard concrete, concrete with iron chips, concrete with aluminum chips and concrete with copper chips, having 18 samples for each type of concrete, which were tested at 7, 14 and 28 days of curing. As for the results obtained in the 28-day compressive strength test, it was obtained that the samples with iron chips increased their strength by 6.48%, regarding the standard concrete; on the other hand, the specimens with aluminum chips reduced their strength by 70.52% with respect to the standard concrete, and finally, the specimens with copper chips showed an increase of 2.90% with respect to the standard concrete. In conclusion, the replacement of the fine aggregate by 10% with iron and copper metal chips improved the compressive strength of the concrete f'c=210 kg/cm2, while the replacement with aluminum chips reduced the compressive strength of the concrete f'c=210 kg/cm2
