Summary
Permeability hysteresis in Indiana Limestone changes irreversibly with increasing confining pressure. Mathematical models describe this path-dependent permeability evolution during compression and unloading cycles.
Area of Science:
- Geology
- Rock Mechanics
- Material Science
Background:
- Understanding rock permeability is crucial for subsurface applications like groundwater flow and carbon sequestration.
- Indiana Limestone exhibits complex behavior under stress, necessitating detailed study of its hydraulic properties.
Purpose of the Study:
- To quantify the evolution of permeability hysteresis in Indiana Limestone under isotropic confining pressures.
- To investigate the impact of monotonic and cyclic loading on permeability changes.
Main Methods:
- One-dimensional constant flow rate tests were performed on Indiana Limestone samples.
- Isotropic confining pressures up to 60 MPa were applied monotonically and during loading-partial unloading cycles.
Main Results:
- Irreversible permeability changes were observed during both monotonic compression and cyclic loading.
- The study identified path-dependent permeability evolution, influenced by the loading history.
Conclusions:
- Permeability hysteresis in Indiana Limestone is a significant and irreversible phenomenon under isotropic compression.
- Developed mathematical relationships can describe the observed path-dependent permeability changes, aiding predictive modeling.

01:25Permeability of Concrete
Permeability in the context of concrete refers to how easily liquids or gases can pass through the material. This quality is crucial for assessing the water-tightness and durability of concrete structures and their resistance to chemical attacks. Concrete permeability can be determined through comparative laboratory tests. These tests typically involve sealing a concrete specimen from the sides, applying water pressure to the top surface with pressure, and measuring the amount of water passing...
01:20Elasticity in Concrete
Upon subjecting concrete to moderate or high uniaxial compressive or tensile stresses, the strain response is non-linear relative to the stress applied. As the stress is removed, the resulting stress-strain curve deviates from the original path traced during loading, creating a hysteresis loop, indicative of the concrete's non-linear and non-elastic properties. Typically, a material's modulus of elasticity, which is a measure of the material's stiffness, is inferred from the linear portion of...
01:20Porosity and Absorption of Aggregate
Aggregates contain pores of varying sizes; while some are completely enclosed within the particles, others open onto the surface, allowing water to penetrate. The porosity of aggregates is a major factor contributing to the overall porosity of concrete, given that aggregates constitute about three-quarters of concrete's volume.
When all pores in an aggregate are filled with water, the aggregate is considered saturated and surface-dry. If left in dry air, water will evaporate until the aggregate...

01:18Porosity in Cement Paste
The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.

01:23Pore Size Distribution
In concrete, the pore size distribution significantly influences the material's properties. Capillary pores, markedly larger than gel pores, form a vast network within partially hydrated cement paste, reducing the concrete's strength and increasing its permeability. This heightened permeability leads to a greater risk of damage from environmental factors like freeze-thaw cycles and chemical attacks, with the extent of vulnerability also being tied to the water-to-cement ratio.

01:22Creep in Concrete
Creep refers to the time-dependent increase in strain under a sustained load, excluding other time-dependent deformations associated with shrinkage, swelling, and thermal expansion in concrete. The primary mechanism behind creep involves the loss of physically adsorbed water from the calcium silicate hydrate within the hydrated cement paste. This process is further exacerbated by concrete's non-linear stress-strain relationship, microcrack development in the interfacial transition zone, and...
