Physical Properties of Silica Sand for Biogrouting Experiments

Experimental data from large-scale model tests investigating microbially induced carbonate precipitation (MICP) for soil improvement. The dataset likely contains measurements of calcium carbonate content, unconfined compressive strength, penetration resistance, and microscopic characteristics for biotreated sand columns. Chunyan Wang published the data on figshare in May 2026.

Use Cases

• Compare reinforcement performance based on calcium carbonate content measurements.
• Analyze spatial uniformity of soil strength based on penetration resistance data.
• Evaluate treatment depth effectiveness based on unconfined compressive strength results.
• Model the effect of grouting pipe configuration (vertical vs. spiral) on reinforcement range.

Strengths

• Includes specific quantitative results, such as effective reinforcement radii of 0.09 m and 0.15 m for different configurations.
• Describes a comparative study of conventional vertical pipes versus a novel spiral pipe layout.
• Provides data from large-scale model tests on 1.5 m-high specimens.

Limitations

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