2.1 Porosity. The porosity is a vast area of concept, can be defined by many terms such as different pore morphologies, pores materials incorporated, pore size, and furthermore, considered on application (Betke and Lieb 2018).From Porosity, we can perceive nature of a material and produce advanced structures (Jiang et al. 2009).The major structural factors of a …
Explicit correlations between two groups of anisotropic effective properties—conductivity and elasticity—are established for porous materials with anisotropic microstructures (non-randomly oriented pores of non-spherical shapes). In the present work, the correlations are derived in the framework of the non-interaction approximation.

Abstract Hygric pore network modelling, which characterises the macroscopic moisture storage and transport properties by simulating the microscopic storage and transport of moisture in the pore elements of the pore network, is a novel method to characterise the hygric properties of building materials. To analyse, verify and/or compare pore networks, a wide array …
