Two-Way ANOVA Results for Cemented Paste Backfill Mechanical Parameters

Uniaxial compression tests on cemented paste backfill specimens under three moisture conditions and loading rates from 0.05 to 2.0 mm/min. The dataset includes results for uniaxial compressive strength, stiffness, peak strain, failure mode, and nonlinear index. Author Chuanchuan Wan published the findings on figshare under a CC-BY-4.0 license in May 2026.

Use Cases

• Modeling the relationship between loading rate and uniaxial compressive strength based on the second-order polynomial relation described.
• Analyzing the effect of moisture condition on material strength and stiffness based on dry, nature, and saturated test results.
• Determining optimal loading rates for underground backfill support based on UCPI analysis results for different moisture conditions.
• Studying failure mode transitions from brittle to tensile-dominated based on moisture-dependent behavior.

Strengths

• Experimental data covers three distinct moisture conditions (0%, 18%, 32%) and a loading rate range from 0.05 to 2.0 mm/min.
• Results include specific fitted optimal loading rates: 1.20, 1.23, and 0.97 mm/min for dry, nature, and saturated conditions respectively.

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 at 5.5 KB, indicating limited scope.
