Abstract
The paper gives an introduction to the basic laws, mainly on a macroscopic scale, for the transport processes which occur in a pore and void system during the service life or the testing of a porous building material. Basic equations for pure potential mass flow, convective flow, and some combined flow mechanisms are presented and discussed. Some versions of the mass balance equation are shown and the binding properties required for solving the mass balance equation are discussed. Apparent transport properties frequently applied when using Fick’s 2nd law are derived. Basic laws describing the distribution profiles during steady state and non-steady state flow processes are summarized. Finally, theoretical and empirical relationships between some transport properties are dealt with.
