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

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

    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. 2. Putsens inverkan på fasadens fuktbalans

    Författare :Kenneth Sandin; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rendering; moisture; driving rain; absorption; drying; provningsmetoder; mätmetoder; kondens; slagregn; fukt; ytterväggar; puts; fasader; pore structure; surface coating; diffusion;

    Sammanfattning : The report deals with the effect of renderings on the moisture balance in facades. The main therne is the moisture mechanism in cnnnection with different moisture sources. Different opinions about moisture in facades and consequences of moisture are mentioned as a background. LÄS MER

  4. 3. Moisture conditions in rain exposed wood joints - Experimental methods and laboratory measurements

    Författare :Maria Fredriksson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; moisture; durability; service life; microclimate; surface moisture; mositure content; Norway spruce; Picea abies; pressure plate; decay; growth ring width; heartwood;

    Sammanfattning : This thesis concerns the moisture conditions in rain exposed wood structures, i.e. wood exposed to high moisture levels. The focus was on the microclimate (the climate at the wood surface) and the material climate (the wood moisture content) in joints. LÄS MER

  5. 4. Studies on the barrier properties of exterior wood coatings

    Författare :Jan Ekstedt; KTH; []
    Nyckelord :Coatings; surfactants; water absorption value; EN 927; paint; additives; moisture dynamics; absorption; desorption; artificial weathering; artificial exposure; computerized tomography; MRI.;

    Sammanfattning : Coatings for exterior wood have two basic functions. One isto give an aesthetically acceptable surface appearance andcolour. The other is to provide protection against wooddegradation by microbiological or physical attack. LÄS MER

  7. 5. Inhibition of Calcium and Zinc Absorption by Phytate in Man Methodological Studies and Hydrothermal Processing of Cereals to Improve Absorption

    Författare :Kerstin Fredlund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; barley; wheat; rye; 65Zn; oats; zinc absorption; whole grains; InsP6; hydrothermal processing; calcium absorption; rice; radionuclide technique; 47Ca; extrinsic labelling; phytate; hydrothermal treatment; myo-inositol; calcium retention; whole-body counting;

    Sammanfattning : A mathematical model based on measurements in a whole-body counter described the retention of calcium in the human body. It was shown that the relative retention of intravenous and orally administered 47Ca in all subjects (n = 10 - 11) were well described by fitting a simple function of time with two free parameters to a few whole-body measurements after day 6, when the unabsorbed calcium had been excreted.
