Grout Diffusion in Coarse-Grained Materials Under Fine-Particle Loss Conditions

Experimental data from constant-pressure grouting tests at 40 kPa on three conditions simulating fine-particle loss. The dataset, created by Shihao Zhang and last updated on 2026-06-01, visualizes and quantifies grout diffusion using Particle Image Velocimetry (PIV) with transparent soil technology. Results detail how fine particle content controls diffusion patterns, from pore clogging to uniform spherical diffusion.

Use Cases

• Modeling grout diffusion patterns based on fine-particle content described in the experiments.
• Analyzing the relationship between pore clogging and grout upwelling/seepage from the test conditions.
• Optimizing permeation grouting parameters for coarse aggregates based on the identified bonding structures.
• Validating numerical simulations of particle migration and clogging mechanisms in earth-rock dams.

Strengths

• Data is derived from controlled laboratory experiments with three distinct test conditions.
• Grout diffusion was visualized and quantified using Particle Image Velocimetry (PIV).
• The dataset is openly available under a CC-BY-4.0 license.

Limitations

• The dataset is small at 43.1 KB, indicating limited scope.
• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
