Pore Size Distribution in Granular Material Microstructure. [PDF]

open access: yesMaterials (Basel), 2017
Pore scale modeling plays a key role in fluid flow through porous media and associated macroscale constitutive relationships. The polyhedral shape and effective local pore size within granular material microstructure are computed in this study by means of the Euclidean Distance Transform (EDT), a local maxima search (non-maximum suppression), and a ...

Porosity of silicon carbide ceramics [PDF]

open access: yesScience of Sintering, 2002
A set of ceramic samples based on silicon carbide with substantially varying integral porosity (from 1 to 10 %) was studied. The pore size distribution was examined by optical microscopy (for pores ranging from 10 mm to hundreds of microns in size ...

Pore size distribution mapping [PDF]

open access: yesMagnetic Resonance Imaging, 1996
Pore size distribution mapping has been demonstrated using NMR cryoporometry in the presence of a magnetic field gradient. This novel method is extendable to 2D and 3D mapping. It offers a unique nondestructive method of obtaining full pore-size distributions in the range 3 to 100 nm at any point within a bulk sample.

A simple method for estimation of permeability of concrete from the compressive strength and pore size distribution based on literature survey

open access: yesJournal of Asian Architecture and Building Engineering, 2023
This study aims to investigate the impacts of compressive strength and curing conditions of concrete on pore size distribution and air permeability. An empirical correlation was developed by analyzing the results from existing studies that measured both ...
