Limestone-Concrete Composite Mechanical Properties from Synthetic Rock Mass Models

A dataset from a study using discrete element method simulations to analyze the size effect on jointed rock-concrete composites. The data likely contains results from uniaxial compression tests, including strength properties, deformation characteristics, and failure features for models of varying dimensions and joint dip angles. The dataset was authored by Hang Liu, shared on figshare under a CC-BY-4.0 license, and last updated in March 2026.

Use Cases

• Modeling the size effect on uniaxial compressive strength (UCS) based on composite dimensions mentioned in the description
• Analyzing the influence of joint dip angle range on compressive modulus based on the study's findings
• Studying failure mode transitions from global to dispersed localized failure based on described energy release patterns
• Comparing the sensitivity of strength versus deformation characteristics to size variations based on the reported analysis

Strengths

• Data is derived from controlled synthetic rock mass models, allowing for systematic parameter variation
• Study explores specific, quantified size thresholds (e.g., 600 mm x 1200 mm for UCS stabilization)
• Examines the impact of precise joint dip angle ranges (e.g., 75°–80° and 30°–35°) on size effects

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data is synthetic, generated from simulation models rather than physical experiments
