The present investigation focused on determining the influence of NaOH concentration on the compressive strength of mortars with foundry slag replacements. Likewise, a physicochemical characterization was carried out such as: apparent density, surface porosity and functional groups, in order to give added value to the waste smelting slag of gold ore through geopolymerization with different concentrations of NaOH. This research presented an explanatory, applied, and quantitative methodology, presenting a unifactorial experimental design. The research sample consisted of forming 40 mortars with a w/c ratio of 0.55, with a binder/aggregate ratio of 1/3 (v/v) and a ratio of cement and gold-bearing smelting slag (1:1 v/v). The foundry slags had a granulometry passing through a No 200 mesh; which were activated with NaOH in concentrations of 2M, 4M, 6M and 8M. These mortars were subjected to mechanical characterization using the ASTM C109 standard for compressive strength at ages of 7 and 28 days. Likewise, they were subjected to physicochemical characterization such as; apparent density through its dimensions, surface porosity through optical microscopy and functional groups through FTIR spectra. The results were obtained that as the concentration of the alkaline NaOH solution increases in the mortar, the compressive strength increases in the same way. Achieving a maximum compressive strength of 27.76 MPa for level 8M in cement mortars with replacement of gold ore smelting slag.
