Limestone-Concrete Composite Strength and Deformation Data Across Sizes and Dip Angles

A 5.5 KB dataset from figshare, last updated March 25, 2026, by author Hang Liu. It contains results from discrete element method simulations analyzing the size effect in jointed rock-concrete composites. The data includes calculated Δσ and ΔE values for uniaxial compressive strength and compressive modulus across different sample dimensions and joint dip angle ranges.

Use Cases

• Modeling the size effect on uniaxial compressive strength based on varying sample dimensions.
• Analyzing the influence of joint dip angle range on the compressive modulus of rock-concrete composites.
• Studying failure mode transitions from global to dispersed localized failure based on energy release patterns.
• Comparing the sensitivity of strength versus deformation characteristics to size variations.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• Results are derived from controlled synthetic rock mass simulations using PFC software.
• Analysis includes specific stabilization dimensions (600 mm x 1200 mm) and dip angle ranges (75°–80°, 30°–35°) where effects are most pronounced.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (5.5 KB), indicating limited scope.
