Abstract: 
Currently one of the main problems encountered in concrete structures is the corrosion, usually caused by the ingress of aggressive agents from the environment outside. This phenomenon has lead to the development of products that aim to prevent the penetration of aggressive agents, including surface treatments for concrete. Within this context, this paper intends to analyze three types of surface protection systems (hydrophobic agents, coating and pore blocker), usually applied in reinforced concrete structures located in marine environment. Water absorption by immersion and capillarity tests were performed, in addition to accelerated corrosion tests, in order to comparatively evaluate the performance of the studied materials. With the procedure adopted, the advantages of using the hydrophobic agents as a surface product protection in the structures was evident. It was also showed that the hydrophobic agents performance was comparatively better than other studied materials.
