Članek predstavlja analizo prodora vode v beton s pomočjo numeričnega
modela, ki temelji na posplošeni formulaciji masnih in toplotnih pretokov v
poroznih materialih. Na podlagi izvršene parametrične analize in dobljenih
profilov vsebnosti vode lahko pripravimo preprost način za določevanje
permeabilnosti betona, ki je ena najvažnejših materialnih lastnosti za oceno
trajnosti in odpornosti betona.
The paper presents a numerical
model based on a generalized mathematical formulations of mass and heat
transfer in porous media, which allows to determine spatial water content
distributions and their changes with time. Different values of properties,
and in particular permeability, can be tested with arbitrary boundary
conditions. In the present work, a sensivity study of saturation to
permeability is conducted for a concrete wall exposed to water ingress at
its base. The model may prove to be a simple tool for on-site first
assessment of concrete permeability by correlating saturation distributions
obtained numerically and levels of wetness evaluated by visual inspection.
