## 1 Introduction
### State of the Art  
The need for the use of this type of salt, despite the negative chemical impact on concrete, is widespread throughout the world's infrastructure management. For this reason, many studies focus on the analysis of these salts, such as the one carried out by [PERSON] et al., which analyzes the behavior of the main de-icing salts applied in infrastructure maintenance, modifying external conditions such as temperature or W/C ratio [2]. Other authors such as [PERSON] et al. developed a decision procedure based on the analytic hierarchy process (AHP) to select the most suitable de-icing salt to be used [3]. Other outstanding studies detail the effect on the concrete using hardened cement paste modified with sodium silicate [4].  
Regarding the study of post-tensioned concrete slabs, most published research focuses on a physical analysis of those elements, studying, for instance, the impact of loads on the structure. In this sense, research such as that of [PERSON] et al. stands out, as it analyzed the impact of loads produced by factors, such as rock fall during construction, comparing reinforced concrete slabs (RC) versus post-tensioned (PT) slabs [5]. Similar publications were presented by [PERSON] et al., which studied the load's impact on rehabilitated concrete slabs [6].  
Focusing on a more economic aspect related to post-tensioned elements, there are also outstanding publications that detail an economic optimization of them, as is the case of the authors [PERSON] and [PERSON] [7]. Such a study presents a methodology based on computational methods to save up to 50% of the budget and quantity of post-tensioned tendons [7].  
However, over-cited studies outstand the ones related to analyzing de-icing salts and their effect on concrete. In this respect, authors such as [PERSON] et al. performed a long-term analysis of chloride penetration and reinforcement corrosion in highway concrete elements exposed since 1990 [8]. Other authors such as [PERSON] et al. focused on the development of numerical models to predict chloride ingress in concrete subjected to atmospheric carbonation and de-icing salts usage [9]. In line with those investigations, authors such as [PERSON] et al. study the performance of concrete in freeze-thaw filled exposure [10]. This study outlined the lack of normative methods related to concrete characterization in the presence of de-icing salts [10]. Authors such as [PERSON] et al. or [PERSON] focused on the concrete properties variation considering freezing and de-icing effects on them [11; 12]. Special infrastructure types with outstanding exposure conditions are analyzed by authors such as [PERSON], [PERSON], who focused on typical parking structure problems [13].  
The current state of the art houses significant research focused on scientific aspects, as has been detailed previously. However, the novelty of this paper and its contribution to the state of the art relies on the engineering perspective that it provides. The reality of infrastructure management demands quick decision making based on inspections and expertise, with a lack of laboratory data analysis. In this sense, the paper aims to provide an overview of it and complement the research field, which is mostly focused on chemical or physical analysis.
