  2. 16. Molecular-level controls on water and organics intercalation in layered minerals

    Author : Jerry Lindholm; Michael Holmboe; Jean-Francois Boily; Virginie Marry; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Minerals; Dynamic Vapor Sorption; montmorillonite; XRD; adsorption model; intercalation;

    Abstract : Layered minerals are naturally abundant and often display a large surface area in relation to their weight. For swelling layered minerals, most of this area is contained between the layers in the interlayer space. READ MORE

  4. 17. Structure of Hardened Cement-Fly Ash Systems and Their Related Properties

    Author : Aimin Xu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water vapour sorption isotherms; thermogravity analysis; mortar; scanning electron microscopy; differential thermal analysis; X-ray diffraction analysis; fly ash; pore structure; microstructure; cement paste;

    Abstract : The influence of fly ash on the pore structure and microstructure of cement paste and mortar has been investigated. The methods applied include water vapour sorption isotherms, scanning electron microscopy, X-ray diffraction analysis and thermogravity/differential thermal analysis. READ MORE

  5. 18. 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. 19. Some aspects of adsorption in displacement washing of pulp

    Author : Karin Mattsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : AbstractThere are many aspects on how to improve the paper pulping process. In the washing sequence improvements to decrease the discharge to the environment can be achieved by closure of the liquid system and recycling liquid from other parts pulp process. READ MORE

  7. 20. Properties of solid wood : responses to drying and heat treatment

    Author : Margot Sehlstedt-Persson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Abstract : The hygro-thermal processes that wood is exposed to during drying and heat treatment lead to different reactions or responses in the wood material. The objective of this thesis has been to study the impact of different drying and heat-treatment strategies on various responses, such as strength, sorption/desorption behaviour, dimensional stability and colour changes.
