Thermogravimetric Data for Cement Pastes with Carbonic Anhydrase, 3-7 Days

38 raw thermogravimetric measurements of portland cement pastes hydrated with carbonic anhydrase enzyme at four CO₂ partial pressures and three ages. The data, produced by Zakira, Umme and deposited in the Texas Data Repository, includes derived summary tables of equivalent-CaCO₃ and Ca(OH)₂ contents computed by a documented tangent-line method.

Use Cases

• Analyze the influence of enzyme aggregation on carbonate mineralization based on comparisons between free and cross-linked enzyme treatments.
• Model the effect of CO₂ partial pressure on cement hydration products based on measurements at 0.04% to 1.0% CO₂.
• Validate thermogravimetric analysis methods by comparing results from derivative-area, naive-endpoint, and tangent-line computation techniques.
• Investigate the time-dependent formation of CaCO₃ and Ca(OH)₂ in cement pastes based on measurements at 3, 5, and 7 days.

Strengths

• Includes 38 raw thermogravimetric measurement files.
• Documents a 2³ factorial design with a replicated center point for controlled experimentation.
• Provides derived summary tables computed by three distinct methods (tangent-line, derivative-area, naive-endpoint) for comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
