  2. 1. Water Absorption in Two-Layer Masonry Systems - Properties, profiles and predictions

    Author : Peter Johansson; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture-diffusivities; masonry; measuremets; moisture-profiles; Material technology; simulations; sorption-isotherms; Materiallära; materialteknik;

    Abstract : The main impetus for this research was the desire to verify models for determining transient moisture profiles in the capillary range. For the evaluations, transient moisture profiles were both simulated and measured, after which the results of the two methods were compared. READ MORE

  4. 2. Moisture content profiles and surface phenomena during drying of wood

    Author : Anders Rosenkilde; KTH; []
    Keywords : computer tomography; diffusion; magnetic resonance; moisture measurement; moisture profiles; surface emission; wood drying;

    Abstract : Timber drying is one of the most important processes whenmanufacturing sawn timber products. The drying processinfluences deformations, surface checking, discoloration andhence, the product quality and the manufacturing costs. READ MORE

  5. 3. 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

  6. 4. Experimental studies of ion transport in cementitious materials under partially saturated conditions

    Author : Nilla Olsson; Avdelningen för Byggnadsmaterial; []

    Abstract : 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. READ MORE
