the present investigation takes for title: “RESISTANCE AND CAPACITY OF ADHERENCE WITH THE CONCRETE FROM THE REINFORCING STEEL SUBJECTED TO CORROSIVE AGENTS“ in the research it was proposed to create a chamber that could emulate the climatic conditions of the city of Cusco with the purpose of induce a corrosion process with the use of a corrosive agent such as the sulfuric acid with a molarity of 0.1 molar as an accelerant in rods of reinforcement steel for a period of time of 1, 2 and 3 months, to later be used in the adhesion test, tensile and bending test, to evaluate the impact of the corrosion produced by the corrosive agents that composes the acid rain in the mechanical properties of the 6mm reinforcement steel and its interaction with the concrete, this research was realized with a quantitative approach, a descriptive level, making use of the hypothetical-deductive method and presented an experimental design, thus being able of verify the verification and validity of the hypotheses established to the problems. Once the rods that were subjected to a corrosion process were extracted, they were subjected to adhesion test, tensile test and bending test. Resulting from a non-probabilistic chamber due to the capacity limitations of the corrosion chamber, taking as a sample the entire population of 168 specimens, distributed in 48 specimens used for the fabrication of dice with the following dimensions 10x10x20cm for the adherence tests, 48 rods of 52cm for the tensile tests and 72 specimens for the fabrication of joist with the following dimensions 15x08x50cm for the for the bending tests; being elaborated and analyzed in 4 forms of presentation of the steel dividing in equal parts the specimens assigned for each test, the first for standard reinforcing steel, the second reinforcing steel with a corrosion process of one month, the third reinforcing steel with a corrosion process of two months and finally reinforcing steel with a corrosion process of three months. After the collection, analysis and evaluation of the results it was possible to demonstrate that the general hypothesis was partially demonstrated, seeing that indeed the corrosion does have a direct effect reducing the resistance of the steel, being demonstrated with the results of the tensile and bending test, being the exception that the resistance to adhesion tension was not increased but rather decreased demonstrated in the results obtained by the adhesion test.
