Matthias Ruf from the University of Stuttgart created a micro-X-ray computed tomography dataset of a Carrara marble core with a diameter of 5 mm. The dataset includes projection and reconstructed images of a sample subjected to a thermal treatment to initiate cracks: heating to 600°C at 3 K/min, holding for 2 hours, and quenching in water. The sample was extracted from a larger 30 mm diameter, 80 mm length core.
Use Cases
- Analyze crack network morphology and density based on the artificially created cracks described.
- Validate computational models of thermal stress fracture based on the specific heating and quenching protocol.
- Train image segmentation algorithms to identify cracks in rock samples based on the reconstructed XRCT images.
- Study the effects of rapid cooling on marble microstructure based on the quenching treatment.
Strengths
- The thermal treatment protocol is precisely documented: heating rate of 3 K/min to 600°C, a 2-hour hold, and quenching.
- Sample dimensions are specified: a 5 mm diameter core extracted from a larger 30 mm diameter, 80 mm length sample.
- The dataset includes both projection and reconstructed images from the micro-XRCT process.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
