MICP Data for Concrete and Soil Remediation Using Calcium Lignosulfonate

Zi-jun Yan's dataset documents a study on microbial-induced calcium carbonate precipitation (MICP) using Bacillus subtilis 168 and calcium lignosulfonate. The data likely contains results from computer simulations and experimental studies evaluating MICP effectiveness in concrete and Chinese soil types. The dataset was last updated on May 11, 2026.

Use Cases

• Optimizing calcium lignosulfonate concentrations for MICP based on experimental results
• Comparing calcite formation effectiveness in different soil types like Yunnan red soil and Henan yellow soil
• Modeling metabolic pathways of Bacillus subtilis enzymes involved in lignosulfonate metabolism
• Assessing ammonia emission reductions from alternative carbon sources in MICP systems

Strengths

• The study employed specific detection techniques (SEM, XRD, FTIR) for evaluation
• Identified a significant enhancement in calcite formation with the addition of 10 g/L calcium lignosulfonate
• Results are applicable to concrete and at least two distinct soil types in China

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset is very small (44.0 KB), indicating limited scope
