The concrete segments are described in the paper. The task was to analyze the corrosion of concrete, the corrosion properties of the building material, the preparation of the surface of the building substrate, the technology of application of organic coatings, the quality control of the protected substrate and the ecological problems of application. Corrosion of concrete causes water to hydrolyze. Consequences of concrete corrosion are the permeability of concrete and the formation of fissures and decay of concrete. Corrosion protection in the construction industry is the protection of the reinforcement mesh by migrating corrosion inhibitors (MCI), which are used to protect the corrosion fittings, they belong to the latest protection technologies. This way the properties of building materials are shown, which show that the most important strength, hardness, elasticity, toughness and appearance and structure are the most important... All materials are subject to corrosion, among the most noble platinum and gold. Surface protection of building surfaces is based on application of coatings, application of corrosion resistant materials, structural - technological measures and protection of the application of the circumstances. Prerequisites for applying a good and durable coating are in addition to the prepared surface and the appropriate conditions under which the coatings are applied. In corrosion analysis there are three important controls, namely: control before coloring, control during coloring and control after coloring. By planning the tests, experiments are planned, the main purpose of these experiments, the aim of the experiments is clear reports of static testing planning and analysis factors. Through the research carried out it can be concluded that the biggest problem is pollution or ecological problems.
