With the rapid development of China’s ice and snow industry, the use of snow-melting agents as a nonpoint source pollution source is increasing, and the impact on the environment cannot be ignored. This paper expounds the agent, purpose, mechanism, and current situation of snow-melting agents at home and abroad and analyzes the national standards, industry standards, and technical indicators of various provinces and cities. This paper puts forward the standard of snow-melting agents, standardizes the production management and detection method of snow-melting agents, improves the quality of snow-melting agent products, and solves the adverse effects of environmental pollution of snow-melting agents. In order to select an economical, effective, and environmentally friendly snow-melting agent application plan that is suitable for cold mountainous areas, the article proposes a TOPSIS method evaluation model with the purpose of source control combined with grey correlation. Calcium, magnesium chloride, chloride salt mixed snow-melting agent (1 : 1 : 1 ratio), and calcium and magnesium acetate are used to melt snow in four specific environments (high cold and high sensitivity, high cold and low sensitivity, low cold and high sensitivity, and low cold and low sensitivity). The pros and cons of the dosage regimen are evaluated. The combined weighting method is used to overcome the shortcomings of the individual subjective and objective weighting methods, and it is concluded that calcium and magnesium acetate is the optimal solution in high-cold and high-sensitivity areas, calcium chloride is the optimal solution in high-cold and low-sensitivity areas, and magnesium chloride is the optimal solution in low-cold and high-sensitivity areas. As the optimal solution, calcium chloride with low cold and low sensitivity is the optimal solution.

“…As a natural phenomenon, water-ice transformation occurs inevitably in a cold environment. The accumulation of ice causes problems in people’s daily lives, such as on roads, electric cables, aircraft, ships, wind turbine blades, and so forth. − Active de-icing and passive anti-icing are good ways to tackle ice accumulation and reduce energy consumption. The special spherical shape of the water effectively reduces the contact area of superhydrophobic coating and water droplets, thus prolonging the water freezing time and achieving the passive de-icing .…”

Waste fabrics have caused serious environmental pollution and resource waste, while recycling is still inefficient and costly. Herein, we designed an efficient and green method of recycling waste fabrics for the preparation of multifunctional photothermal protective materials. Modified carbonized fibers (MCFs) were obtained from carbonized waste fabrics and modified with dopamine and dodecylamine. Thanks to the photothermal synergy between polydopamine and the CFs, the MCF coating exhibited more than 95% light absorptivity in the visible wavelength range, which can rapidly heat up to 95.3 °C within 120 s under 1 kW/m 2 illumination. The excellent photothermal property in collaboration with superhydrophobicity endows MCF coating with obviously active de-icing and passive anti-icing properties. Moreover, the surface of the coated fabric can maintain a temperature of 20.1 °C under 0 °C with 1 kW/m 2 illumination, illustrating the personal thermal management (PTM) characteristics. Furthermore, the MCF coatings exhibited excellent mechanical and chemical durability, which significantly extended their service life. More importantly, the noteworthy breathability made the fabric suitable and comfortable to wear. This self-cleaning photothermal protective coating with PTM, active de-icing, and passive anti-icing properties greatly broadens the application of recycled waste fabrics and the utilization of sustainable solar energy.

“…For this reason, many studies focus on the analysis of these salts, such as the one carried out by Sanchez Thomas 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 Guoju Ke 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].…”

This article expounds on the problem of the use of de-icing salts in the corrosion of steel rebars in bridge decks and their effect on post-tensioning elements. In particular, this paper focuses this problem on structures affected by an aggregate–alkali reaction and without any waterproof treatment using the example of one structure whose repair was carried out in 2020. In this structure, the internal stresses due to the aggregate–alkali reaction caused longitudinal cracks in the upper face of the deck, through which the penetration of chloride ions was concentrated, causing, finally, the brittle fracture of the steel bars and the corrosion of the prestressing elements. This article also explains some conclusions about the most probable mechanisms that resulted in the brittle fracture of the steel bars due to the extraordinary and unexpected nature of this phenomenon.
