This study evaluates the damage to concrete caused by sulfate attack in the province of Chilca, south of Lima, and its impact on the durability of structures. In this coastal area, buildings have experienced notable deterioration due to the high concentration of sulfates in the soil and environment. The main objective is to understand the effects of sulfate on the properties and durability of concrete through controlled exposure of specimens. Periodic evaluations of strength and durability were performed as the specimens were exposed to sulfates for specific periods. A quantitative experimental methodology was used to establish a clear connection between cause and effect. Laboratory tests were conducted with 40 specimens across 4 designs. Finally, the samples were evaluated in both fresh and hardened states. The study considers variables such as sulfate concentration, compressive strength, and volumetric change to obtain precise information about HS concrete behavior against sulfates. The results helped develop more effective design and construction strategies. The AM-C15P design excelled in qualitative analysis, while the AM-C10P design showed superior compression resistance with 477 Kg-f/cm² and minimal volumetric change of -1.42 cm³. In summary, this study focused on evaluating concrete damage at different ages caused by sulfate attack through periodic evaluations of specimens, aiming to improve the design and construction of more sulfate-resistant structures.
