Summary: The study found that adding fly ash or basalt fiber can effectively improve the chloride corrosion resistance of CAC and reduce the chloride ion concentration. The peak chloride concentration appears at 3-5 mm in the concrete and increases with exposure time.

Summary: Understanding groundwater recharge mechanisms is crucial for sustainable groundwater resource assessment and management, especially in arid and semiarid areas. This study utilized chloride and stable isotopes to estimate groundwater recharge in the Ordos Plateau, northern China. The relationship between chloride concentrations in saturated zone water and soil water residence time was derived, providing insights into water flow and chloride transport. The study concluded that intense rainfall events were the main contributors to groundwater recharge, while small rainfall events only contributed to chloride flux on the soil surface.

Summary: This study aimed to understand the effect of root zone temperature on salt exclusion, growth, and stomatal conductance in Shiraz grape vines. The results showed that some rootstock genotypes exhibited enhanced shoot sodium and chloride exclusion in response to salt treatment under high root zone temperature.

Summary: The effect of BFS (Blast Furnace Slag Fine Aggregate) on freezing and thawing resistance under chloride environment was investigated. It was found that using BFS with fine grain size and increasing the mixing ratio of BFS to natural sand improved the freezing and thawing resistance. The study also showed that mortar using BFS had higher electrical resistivity and lower effective chloride ion diffusion coefficient, indicating better resistance to chloride penetration. The analysis of reaction products at the BFS-cement paste interface revealed the presence of hydrotalcite-like compounds, which contributed to the improvement of chloride ion penetration resistance in concrete mixed with BFS.

Summary: This study analyzed the large folds in longwall mining of potash salts, identifying a separate flexure-like fold with a height of over 30 meters at the intersection of two fold systems. It was found that hydrocarbon gases could have been generated in situ from organic matter of salts during fold catagenesis. The study also established the influence zone of a 30-meter fold.

Summary: The study focuses on the impact of acid mine drainage on the surface watercourses of Chusovaya river basin, examining the behavior of metals in contaminated waters and aiming to understand the migration forms, main secondary mineral phases, and stability of formed minerals. Results show that metals occur in various forms in polluted waters and their migration is influenced by different factors.
