RRT2: Self-Healing Concrete Inter-Laboratory Test Data from 9 European Labs

Data from the second inter-laboratory testing program (RRT2) of the EU COST action SARCOS, focusing on self-healing concrete with MgO-based expansive minerals. Nine laboratories from seven European countries participated, testing fiber-reinforced concrete specimens using water permeability, capillary absorption, and crack width measurements. Specimens were monitored for self-healing after 1, 3, and 6 months of submersion in water.

Use Cases

• Compare self-healing performance of concrete with and without MgO-based mineral additions based on water permeability test results.
• Analyze the relationship between crack width measurements and healing efficiency over time based on optical microscopy data.
• Evaluate the durability of self-healed concrete specimens based on chloride ingress test results.
• Benchmark laboratory testing methodologies for self-healing concrete based on data from nine different institutions.

Strengths

• Data originates from a structured inter-laboratory program involving 9 laboratories from 7 European countries, suggesting methodological rigor.
• Testing includes multiple complementary methods: water permeability, capillary absorption, crack width measurement, and chloride ingress.
• Healing process was monitored at three predefined time intervals: 1, 3, and 6 months.

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.
