  2. 1. Surface characterisation of thermally modified spruce wood and influence of water vapour sorption

    Author : Susanna Källbom; Magnus Wålinder; Kristoffer Segerholm; Dennis Jones; Marko Petrič; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermally modified wood; Norway spruce; inverse gas chromatography IGC ; dynamic vapour sorption DVS ; X-ray photoelectron spectroscopy XPS ; surface energy; Värmebehandlat trä; gran; omvänd gaskromatografi IGC ; dynamic vapour sorption DVS ; röntgenelektronspektroskopi XPS ; ytegenskaper; ytenergi;

    Abstract : Today there is growing interest within the construction sector to increase the proportion of biobased building materials made from renewable resources. By-products or residuals from wood processing could in this case be valuable resources for manufacturing new types of biocomposites. READ MORE

  4. 2. Characterisation of thermally modified wood for use as component in biobased building materials

    Author : Susanna Källbom; Magnus Wålinder; Dennis Jones; Kristiina Lillqvist; Kristoffer Segerholm; Marko Petrič; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermally modified wood TMW components; surface properties; inverse gas chromatography IGC ; water sorption; dynamic vapour sorption DVS ; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : The building sector shows growing interest in biobased building materials. Wood components, here defined as ground or milled wood, i.e. by-products (residuals/residues) from wood processing, such as sawdust or shavings, are valuable raw materials for new types of durable biocomposites suitable for outdoor building applications.

  5. 3. Thin water and ice films on minerals : a molecular level study

    Author : Merve Yeşilbaş; Jean-François Boily; Johannes Messinger; Grégory Lefèvre; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water; ice; cryosalt; minerals; rocks; atmosphere; Dynamic Vapour Sorption; FTIR; cryo-FESEM; fysikalisk kemi; Physical Chemistry;

    Abstract : Minerals in Earth’s crust and suspended in the atmosphere form water or ice films as thin as a few nanometers to as thick as a few micrometers, and beyond. Mineral-bound water and ice films in terrestrial systems (e.g. READ MORE

  6. 4. Continuum Mechanics Modelling of Corrugated Board

    Author : Ulf Nyman; Institutionen för byggvetenskaper; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; assumed natural strain shell; failure criterion; lifetime; reliability; moisture transport; sorption hysteresis; corrugated board; hygro-elasticity; Materiallära; materialteknik;

    Abstract : The storage of compressive loaded boxes in an environment with naturally varying humidity is a practical issue in corrugated board employment. Time dependent variables such as moisture content, strain fields, stress fields and material strength play important roles for the time to failure. READ MORE

  7. 5. Interaction of water with supplementary cementitious materials: Hydration mechanism, microstructure and moisture transport

    Author : Liming Huang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydration; moisture transport; Supplementary cementitious materials; electrical conductivity; formation factor; durability; microstructure;

    Abstract : Supplementary cementitious materials (SCMs) offer a sustainable solution to reduce carbon emissions from the production of cement and concrete. This dissertation explores the impact of SCMs and the related additives on the hydration process of cementitious materials, which can affect their microstructure and transport properties. READ MORE
