1. Moisture Transport in Porous Media. Modelling Based on Kirchhoff Potentials
Sammanfattning : The work presented in this thesis is focused on the development of the new concept to describe isothermal moisture transport using Kirchhoff potentials. The first four papers deal with moisture transport in porous media using Kirchhoff potentials. The last three papers deal with wood. LÄS MER
2. Moisture transport and fixation in porous materials at high moisture levels
Sammanfattning : 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. LÄS MER
3. Experimental studies of ion transport in cementitious materials under partially saturated conditions
Sammanfattning : Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. LÄS MER
4. Moisture permeability of mature concrete, cement mortar and cement paste
Sammanfattning : Moisture permeability tests were performed on specimens of concrete, cement mortar and cement paste with the bottom side in water or in moist air and the upper side in a relative humidity of 33 %. The distribution of the relative humidity within the specimen was measured, at stationary conditions, as well as the amount of water which pass through the specimen. LÄS MER
