Sandstone Cerchar Abrasivity Index Values Under Different States

Cerchar Abrasivity Index (CAI) values for sandstone samples measured under various conditions. The dataset, created by Yafeng Yao, is a 5.5 KB Excel file last updated in April 2026.

Use Cases

• Compare CAI values across different sandstone states to assess abrasivity variation.
• Correlate specific CAI measurements with rock properties like moisture content or weathering state.
• Establish baseline CAI statistics for sandstone classification in geotechnical databases.
• Validate predictive models for tool wear using recorded CAI test results.

Strengths

• Openly licensed under CC-BY-4.0 for unrestricted reuse.
• Provides a focused collection of CAI test results for a specific rock type.

Limitations

• Extremely small 5.5 KB size indicates very limited sample scope.
• Lacks metadata on sample count, measurement methods, or specific test states.
• No temporal or geographic context for the source samples.
