Cemented Paste Backfill Mechanical Test Results Under Varying Moisture and Loading Rates

Uniaxial compression tests on cemented paste backfill (CPB) specimens under three moisture conditions (0%, 18%, 32%) and loading rates from 0.05 to 2.0 mm/min. Author Chuanchuan Wan published the results on figshare in 2026, showing a polynomial relationship between strength and loading rate with a transition region around 1.0 mm/min.

Use Cases

• Modeling the relationship between uniaxial compressive strength (UCS) and loading rate based on the second-order polynomial relation described
• Comparing failure modes and material brittleness based on moisture condition as described in the study
• Determining optimal loading rates for underground backfill support based on the UCPI analysis results for dry, natural, and saturated conditions

Strengths

• Data includes tests across three distinct moisture conditions (dry 0%, nature 18%, saturated 32%) and a range of loading rates (0.05 to 2.0 mm/min)
• Analysis provides specific fitted optimal loading rates: 1.20, 1.23, and 0.97 mm/min for the respective moisture conditions

Limitations

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