Volume 61, Issue 1, Pages 51–63, ISSN (Print) 0239-7528, DOI: 10.2478/bpasts-2013-0004, May 2013 Publication History: Published Online: 2013-05-01 Abstract A general approach to modelling chemical degradation processes in building materials, due to combined action of variable hydrothermal, chemical and mechanical loads, is presented. Mechanics of multiphase porous media and damage mechanics are applied for this purpose, and kinetics of degradation processes is described with evolution equations based on thermodynamics of chemical reactions. The mass-, energy - and momentum balances, as well as the evolution equations, constitutive and physical relations are briefly summarized. Then, the model governing equations are numerically solved with the finite element method. Three examples of the model application for analyzing degradation processes of building materials are presented and discussed. The first one deals with capillary suction of the salt solution by two different building materials, the second one with the salt crystallization during drying of a brick wall, and the third one concerns calcium leaching from a concrete wall due to the chemical attack of pure water under pressure gradient at two different temperatures.
