Tensile Response and Microstructure of Fiber-Reinforced Frozen Loess

This experimental dataset investigates the mechanical behavior of polypropylene fiber-reinforced loess under freezing conditions. It contains measurements of tensile strength influenced by fiber content, freezing temperature, and loading rate, paired with microstructural observations. The data provides evidence for optimal fiber reinforcement at 0.3% content, showing a 71.4% increase in tensile strength compared to unreinforced soil.

Use Cases

• Modeling tensile strength as a function of fiber content and freezing temperature for engineering design
• Analyzing the transition from brittle to ductile failure modes in reinforced frozen soil
• Correlating macroscopic stress-strain responses with microscopic network structures
• Optimizing fiber content to prevent agglomeration and structural weakening

Strengths

• Dataset is openly licensed under CC-BY-4.0, permitting broad reuse
• Combines macroscopic mechanical testing with microstructural analysis
• Experimental results include a specific, quantified strength increase of 71.4% at 0.3% fiber content

Limitations

• Column names and a precise row count are not provided, limiting immediate analysis
• The dataset consists of a single XLSX file; the internal structure and variable definitions are unclear
• The listed update date of 2026-03-19 is in the future, indicating a metadata error
