Pore Size Distribution01:23

Pore Size Distribution

537
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.

Porosity and Absorption of Aggregate

863
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...

Porosity in Cement Paste

516
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.
The balance of water to cement in the mix is...

Area of Science:

  • Geosciences
  • Physics
  • Chemistry

Background:

  • Multiphase flow in porous media is controlled by local wetting properties.
  • Spatial variability of wettability in situ is difficult to quantify using micro-CT imaging.
  • Estimating contact angles is challenging due to partial-volume effects and segmentation uncertainties, hindering reliable pore-scale wettability heterogeneity resolution.

Purpose of the Study:

  • To introduce a novel automated geometric algorithm for pore-by-pore contact angle measurement.
  • To overcome limitations of existing methods in resolving pore-scale wettability heterogeneity.
  • To enable accurate wettability characterization for various subsurface applications.

Main Methods:

  • Developed an automated geometric algorithm to measure pore-by-pore contact angles.
  • Bypassed explicit contact loop detection by extrapolating surface normals from neighboring two-phase interfaces.
  • Validated the method on synthetic datasets and applied it to water-wet and mixed-wet rock samples.

Main Results:

  • The algorithm reduces sensitivity to segmentation errors and partial-volume effects.
  • Quantified measurement uncertainty, noting amplification in smaller pores.
  • Revealed significant wettability heterogeneity masked by bulk averages, with 40% of pore space in intermediate-wetting regimes in a mixed-wet sample.
  • Demonstrated that wettability heterogeneity broadens the contact angle distribution.

Conclusions:

  • The novel algorithm provides accurate, spatially resolved wettability characterization.
  • Wettability heterogeneity significantly impacts multiphase flow behavior.
  • Open-source software is available for applications in CO2 sequestration, hydrogen storage, and multiphase flow.
