  1. 1. Calorimetric methods for the study of fungi on building materials

    Författare :Yujing Li; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fungal growth; fungal activity; ergosterol; humidity; temperature; calorespirometry; oxygen; mätmetoder; röta; svamp; byggmaterial; påväxt; kalorimetri; microcalorimetry; isothermal calorimetry; Fungi; building materials; mould; Serpula lacrymans; rot fungi;

    Sammanfattning : The aim of this project is to study the fungal growth habits on building materials as a function of humidity, temperature and other environmental parameters. The method of calorimetry is used as a way to quantify fungal activity on building materials. LÄS MER

  3. 2. Determination of the Critical Moisture Level for Mould Growth on Building Materials

    Författare :Pernilla Johansson; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crawl space; Fungus; Mould resistance; Wood; Building materials; Mould; Critical moisture level; Attic; Relative humidity; Cyclic conditions; Laboratory method;

    Sammanfattning : The susceptibility to mould growth varies between building materials. The factors that most affect mould growth, the relative humidity (RH) and temperature also vary in different parts of buildings. One way of preventing the growth of mould in buildings is therefore to choose building materials that can withstand the expected conditions. LÄS MER

  4. 3. Biological growth on rendered façades

    Författare :Sanne Johansson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature; render; radiation; photosynthesis; moulds; mosses; mortar; moisture; lichens; Imaging-PAM; humidity; heat capacity; heat; ETICS; algae; biological growth; calorimetry; desiccation tolerance;

    Sammanfattning : Biological organisms have an incredible ability to adapt to almost any environment and the humans activities on earth have created many new habitats for different kinds of organisms. For example can certain organisms grow on rocks and vertical cliffs, and when humans started building houses with mineral based façades, some organisms found that these were new habitats to live on.

  5. 4. Uttorkning av betong : inverkan av cementtyp, betongkvalitet och omgivande fuktförhållanden

    Författare :Niklas Johansson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; betong; materialegenskaper; skador; uttorkning; fukt; golv;

    Sammanfattning : Uttorkning av betong är ett ämnesområde som under lång tid varit i fokus. Genom åren har många skadefall kunnat kopplas till alltför fuktiga betonggolv. Det är inte betongen som tar skada utan vissa material som placerats i direkt anslutning till betongen. LÄS MER

  7. 5. Non-Invasive Monitoring of Architectural Heritage

    Författare :Jenny Hällström; Bebyggelsevård; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remote sensing; lidar; laser-induced fluorescence; documentation; hyperspectral; non invasive; non destructive; sustainable maintenance; conservation planning; monitoring; Coliseum; architectural conservation; restoration; Övedskloster; deterioration; Lateran Baptistery; stone; brick; thematic mapping; in situ; imaging; biodeteriogens;

    Sammanfattning : The on-site documentation and examination of architectural heritage has presented challenges for traditional analysis methods in the form of, among other things, large complex structures, sites and environmental conditions. In recent years there has been growing interest in assessing progressing deterioration processes and material analysis, with an emphasis on sustainable conservation and maintenance planning. LÄS MER
