Abstract

The general objective of this research is to determine the influence of the replacement of fine aggregate with copper slag on the properties of a concrete f'c = 210 Kg/cm2 in a fresh and hardened state. This research was applied with an experimental design, the sample It is composed of 24 4” x 8” cylindrical specimens. As part of the development of the research, mixtures were prepared for a standard concrete and mixtures with 10%, 20% and 30% replacement of fine aggregate with copper slag. The properties evaluated for these mixtures were consistency and resistance to compression. The results obtained for fresh concrete show that as the substitution of fine aggregate for copper slag increases, the consistency of the mixture goes from plastic to fluid. Regarding the properties of the concrete in the hardened state, the compressive strength of the different substituted mixtures was studied, where it was observed that the optimal value to replace the fine aggregate with copper slag is 10%, giving an increase in 16.9% with respect to the standard concrete, however, it was determined that the 20% and 30% mixtures gave similar results to the standard concrete, demonstrating that substitution within said ranges is safe.
