Abstrakty

EN

The actual moisture content of a ceramic brick under changing borderline conditions is experimentally determined. The results of an experiment are compared with the results of numerical simulation. A simplified model for evaluating the actual moisture content of a hysteretic building material is suggested.

PL

Określono eksperymentalnie rzeczywistą zawartość wilgoci w cegle ceramicznej w zmiennych, skrajnych warunkach. Wyniki eksperymentu porównano z rezultatami symulacji numerycznej. Zaproponowano uproszczony model oceny rzeczywistej zawartości wilgoci w histerezowym materiale budowlanym.
