Construction and environmental conditions such as seawater chlorides have affected the initial properties of many reinforced concrete structures on the seacoast (Poursaee, 2016). The Peruvian coast has not been the exception where several ports and buildings have reduced their durability (Rivva, 2006). In 2018, it was estimated that 60 % of Peruvian buildings were self-built with structural deficiencies (CAPECO, 2018). In addition, a study in 2015 showed that the owners preferred the master builders over a professional for construction management (CAPECO, 2015). Due to this, it is necessary to study the process of deterioration of reinforced concrete by the action of sodium chloride. Studies of the corrosive process have been varied in the world (Feng et al., 2021); However, in the line of investigation of reinforced concrete subjected to cycles of moistening and drying by chlorides in Peru, there has only been a record of reinforced concrete subjected to sodium chloride (Rimarachín, 2013) and reinforced concrete subjected to ferric chloride. (Torres, 2019; Rojas, 2021). For this reason, the objective of this investigation has been the analysis of the effects generated over time on the properties of medium to low strength reinforced concrete using Portland type I Sol cement, due to exposure to wetting and drying cycles of a sodium chloride solution of 100 grams/liter (g/L). For this purpose, concrete test tubes were made based on Portland cement type I brand Sol with water–cement ratios (w/c) of 0,60, 0,65 and 0,70 and ∅ 5/8“ reinforcing steel, which were subjected to a accelerated corrosion method based on continuous wetting and drying cycles (Díaz, 1994). The physical property considered was the weight, and for the resistant property, the resistance to compression. The main results were that, the greater the number of wetting and drying cycles due to the action of sodium chloride in solution in the reinforced concrete specimens, and a greater water–cement ratio, the greater variations in weight and compressive strength were presented. Finally, the present investigation will serve as a contribution to the knowledge of the process of deterioration of reinforced concrete over time due to the attack of sodium chloride in structures of the marine coast, and also as a guide for the following investigations oriented to the corrosive process.
