Abstract
The paper describes the experiment conducted to validate predictions, derived by the heat and mass transfer numerical analysis computer code MA1DW, for dynamic moisture-content evolution. The tests included two samples: an autoclaved aerated concrete (AAC) and a regular concrete rendered by thermal plaster (CTP). An excellent fit was derived for temperature evolutions in both samples. A good fit was derived for the trends and general evolutions of moisture contents, with much better absolute-value approximations for the AAC samples. This demonstrated the significance of establishing reliable Design Values for material coefficients. The validation actually supplied the confidence for undertaking the further steps of development and modification of the computer code into a 2-D analysis tool.
