Pearson Correlation Coefficients for Waste Glass and Rice Husk Concrete Properties

A 5.5 KB Excel dataset containing Pearson correlation coefficients from a study on low-carbon concrete. The data, authored by Jiayuan Lou and last updated in April 2026, supports research into the synergistic use of silicon-rich solid wastes like glass sand, glass powder, and rice husk ash. It explores the relationship between the silicon-to-calcium ratio and concrete properties such as workability, strength, and resistance to water, sulfate, and carbonation.

Use Cases

• Modeling the relationship between silicon-to-calcium ratio and concrete strength based on the described optimal range of 0.46–0.58.
• Analyzing durability performance against sulfate attack and water penetration based on the reported mass loss and ultrasonic velocity data.
• Developing constitutive models for shear damage in concrete based on the nonlinear response characteristics described for varying Si/Ca ratios.
• Optimizing mix designs for waste-incorporated concrete based on the microstructural analysis linking composition, structure, and performance.

Strengths

• Data is derived from a systematic experimental study investigating three types of silicon-rich solid wastes.
• Specific performance metrics are provided, such as a 0.54% mass loss rate after 180 cycles and a 2.6% ultrasonic velocity reduction.
• Dataset is openly shared under a CC-BY-4.0 license, facilitating reuse and citation.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download to understand the data structure.
• The dataset is very small (5.5 KB), indicating limited scope, likely containing summary statistics or a small set of correlation results.
• The temporal coverage of the underlying experiments is not specified in the metadata.
