“…Previous studies have focused on the durability, deterioration, and service life of concrete structures, including numerical models [14][15][16] and experimental studies [17,18]; however, these studies mainly focused on constructions located above ground level and ignored the impact of the different factors on the structures located below ground level. Wei et al [19] investigated how acids coming from the atmosphere and retained in the superficial layers of the ground induce concrete degradation decreasing the compressive strength and increasing the corrosion coefficient of concrete; it was identified that the main reason for premature deterioration of concrete is due to the changes in temperature where the corrosion coefficient was increased about two times for samples exposed to 40 • C. However, the compressive strength results did not show any significant changes during the 90 days of exposition.…”

Coating materials are considered one of the most antique materials of human civilization; they have been used for decoration and the protection of surfaces for millennia. Concrete structures—due to their permanent exposure to different types of environments and contaminants—require the use of coatings that contribute to its preservation by reducing the corrosion of its components (steel and aggregates). This article intends to introduce the principal causes of concrete deterioration and the coating materials used to protect concrete structures, including a summary of the coating types, their advantages and disadvantages, and the latest developments and applications. Furthermore, this paper also assesses brief information about the potential challenges in the production of eco-friendly coating materials.

“…Materials are exposed to external conditions and physical influences which can lead to unwanted changes in material characteristics and usability, which means their degradation. An example of unfavorable external conditions is temperature changes and/or the presence of aggressive components of the environment 7 .…”

This paper deals with the possibilities of analysis of building materials in terms of chemical composition. Using the method of infrared spectroscopy, we can determine the organic compounds in coatings, adhesives, grout, and silicate materials. Building material characteristics have to be in accordance with the standards. However, due to external conditions, the material can degrade during its life. Observations and chemical analyses of the building materials must be performed to be able to do remediation and reconstruction of the historical building. Infrared spectroscopy was chosen as the best for qualitative analysis of organic admixtures in building materials.

“…The overall impact of adverse environmental conditions can result in a degradation process of the building material. The building material then loses its physical, chemical and mechanical properties and stops withstanding environmental influences [7]. The object should then be remediated and reconstructed to stay safe.…”

This paper deals with the chemical analysis of the coating on building materials which were used for construction of Mánes bridge in Prague. It is a historical bridge which is more than a hundred years old. Using the method of infrared spectroscopy, we can determine the organic and inorganic compounds in coatings, adhesives, grout, and polymer materials. The organic compounds are added into the concrete and other building materials due to improvement of physical and mechanical properties such as compressive strength, tensile strength, modulus of elasticity or water absorption. The building materials can be covered with the coating for protection against mechanical damage. The chemical analysis of the building material is important to know before reconstruction and remediation of the historical buildings. As a result, the infrared spectrum of the coating was measured and it was determined that the coating was on the acrylate base.
