2. 1. Moisture Balance in Painted Wood Panelling

   Author : Stefan Hjort; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture transport; numerical simulation; rot; wood; moisture conditions; paint;

   Abstract : Over the last years thousands of houses have been damaged by wood rot in the exterior wood panelling due to excessive moisture conditions. This thesis is about moisture conditions and the way moisture enters and exits painted wood panelling structures. READ MORE

4. 2. Moisture transport and fixation in porous materials at high moisture levels

   Author : Mårten Janz; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building construction; water retention curve; diffusivity; suction; Moisture transport; moisture fixation; absorption; capillary transport; byggnadsteknik;

   Abstract : The work presented in this thesis focuses on developing methods of measuring moisture properties at high moisture levels. Paper I deal with a new method of measuring moisture diffusivity at high moisture levels. Papers II to IV present methods of measuring moisture storage capacity as well as results from such measurements. READ MORE

5. 3. Moisture redistribution in screeded concrete slabs

   Author : Magnus Åhs; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hysteresis; Scanning; Relative humidity; Moisture redistribution; Sorption isotherms; Screeded slab;

   Abstract : The principal objective for this licentiate thesis is to develop a methodology and evaluation model in order to make the future relative humidity in a screeded concrete slab predictable. Residual moisture in screeded concrete slabs may redistribute to the top screed surface under semi-permeable flooring, thus elevating the relative humidity, RH, and possibly exceed the critical humidity level.

6. 4. Moisture Induced Stress Perpendicular to Grain in Timber Structures

   Author : Martin Häglund; Avdelningen för Konstruktionsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood.; timber; perpendicular to grain; load combination factor; tensile stress; mechano-sorption; Moisture induced eigen-stress; varying moisture content;

   Abstract : Timber structures and wooden element are in general affected by moisture and moisture variation in different ways. Their hygroscopic properties result in adsorption of water when wetted and in desorption when dried. READ MORE

7. 5. Redistribution of moisture and ions in cement based materials

   Author : Magnus Åhs; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture redistribution; ion redistribution; cement based materials; hysteresis; sorption isotherm; scanning;

   Abstract : There were two principal objectives for this thesis. The first was to develop a methodology and evaluation model of moisture redistribution in order to make the future relative humidity in a screeded concrete slab predictable. The second objective was to develop a method to determine the critical humidity for ion transport in concrete. READ MORE
