Mechanical and Durability Properties of Foamed Lightweight Soil with Desulfurization Ash

A 2026 study by Haochen Lei investigates the properties of foamed lightweight soil synthesized from industrial solid waste desulfurization ash, ground granulated blast-furnace slag, and cement. The dataset likely contains results from systematic tests on mechanical properties, expansion characteristics, durability, and environmental safety, compared against ordinary portland cement lightweight soil. Microstructural analysis was performed using X-ray diffraction and scanning electron microscopy.

Use Cases

• Predicting compressive strength of foamed lightweight soil based on wet density and material ratios mentioned in the description.
• Analyzing the relationship between desulfurization ash content and volumetric expansion rate in lightweight soils.
• Assessing environmental safety for road subgrade applications based on toxicity leaching test results for heavy metals.
• Comparing the durability performance of waste-based lightweight soil against conventional cement-based mixtures.

Strengths

• Specific optimal performance parameters are provided, including a wet density of 800 kg/m³ and a 28-day compressive strength of 1.53 MPa.
• Environmental safety is quantitatively assessed, with toxicity leaching tests confirming heavy metal concentrations are below regulatory limits.
• Microstructural analysis using XRD and SEM provides a basis for understanding strength development mechanisms.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The description suggests durability of the DA-FLS material is inferior to the OPC-FLS control.
