Polyacrylamide Gel Data for Toughening Cement-Based Materials

Experimental data on polyacrylamide (PAM) gel properties under mixed-salt conditions for cement toughening. The dataset, authored by Hongrong Li and last updated in May 2026, includes results showing tensile strength and toughness increases of over 116% and 143% at specific salt concentrations. It proposes a 'double salt effect' mechanism for enhancing cement-based material performance.

Use Cases

• Modeling the relationship between salt ion concentration and polymer gel mechanical properties based on described compound salt experiments.
• Investigating the 'double salt effect' mechanism on material toughness as proposed in the study.
• Developing predictive models for cement-based material performance using resistance measurement correlations mentioned in the description.
• Benchmarking new high-toughness cement formulations against the reported PAM gel property enhancements.

Strengths

• Includes specific quantitative results, such as a 116.39% increase in tensile strength and a 143.88% increase in toughness at 2 M compound salt concentration.
• Proposes a novel 'double salt effect' mechanism, providing a conceptual framework for the data.
• License is clearly defined as CC-BY-4.0, facilitating open reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a DOCX document (22.6 MB), which suggests the data may be embedded in a textual report rather than a structured, machine-readable format.
