Silica-Calcium Ratio of C-S-H Gel in Waste Glass and Rice Husk Concrete

Experimental data on the properties of Waste Glass and Rice Husk Concrete (WGRC) with varying silicon-to-calcium ratios. The dataset, authored by Jiayuan Lou and last updated in April 2026, contains results from systematic investigations into workability, mechanical properties, and durability. It includes findings on optimal strength ranges, resistance to water penetration and sulfate attack, and a developed shear damage constitutive model.

Use Cases

• Modeling the relationship between Si/Ca 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 metrics.
• Developing constitutive models for nonlinear shear response based on the described shear damage model coupling composition, structure, and performance.
• Optimizing low-carbon concrete mix designs for multiple solid wastes based on the described synergistic regulation strategy.

Strengths

• Includes specific performance metrics, such as a 0.54% mass loss rate after 180 drying-wetting cycles and a 2.6% ultrasonic velocity reduction.
• Defines optimal material performance ranges, including a Si/Ca ratio of 0.46–0.58 for overall strength and 0.58 for maximum carbonation resistance.
• Data is openly shared under a CC-BY-4.0 license, facilitating reuse and modification.

Limitations

• Row count is unknown, which may limit suitability assessment for machine learning.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (5.5 KB), indicating limited scope and likely a summary or key results rather than raw experimental records.
