  1. 1. Shrinkage and Related Properties of Alkali-Activated Binders Based on High MgO Blast Furnace Slag

    Author : Abeer Humad; Andrzej Cwirzen; John L. Provis; Karin Habermehl-Cwirzen; Andrzej Garbacz; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkali-activated slag; alkali-activated materials; high-MgO blast furnace slag; shrinkage; creep; carbonation; strength; heat curing; Byggmaterial; Building Materials;

    Abstract : Concrete is the second most used material in the world just after water. A drawback is that it is mostly based on Portland cement, which has an extremely high carbon footprint reaching a staggering 900 kg/tonne. The carbon dioxide emissions related to the production of the Portland cement accounts for nearly 8 % of the global total. READ MORE

  2. 2. Condensation and frost formation in fibrous thermal-insulation materials

    Author : Tomáš Vrána; Folke Björk; Ove Söderström; Kjartan Gudmundsson; Carsten Rode; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibrous thermal insulation; Stone wool; Cellulose; MAterial properties; Moisture transport; Condensation; Frost formation; Exterior conditions; Interior conditions; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Construction materials; Konstruktionsmaterial;

    Abstract : Heavily insulated constructions are at present being used to strike at the vast energy consumption in residential buildings and commercial alike. They introduce a high-thickness layer of thermal insulation in the building envelopes. READ MORE

  3. 3. Elastic properties and phase stability of shape memory alloys from first-principles theory

    Author : Chun-Mei Li; Levente Vitos; Denis Music; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction materials; Konstruktionsmaterial;

    Abstract : Ni-Mn-Ga and In-Tl are two examples of shape memory alloys. Their shape memory effect is controlled by the martensitic transformation from the high temperature cubic phase to the low temperature tetragonal phase. Experimentally, it was found that the martensitic transformation, related to the elastic properties, is highly composition-dependent. READ MORE

  4. 4. Reuse of construction materials : Environmental performance and assessment methodology

    Author : Liselott Roth; Mats Eklund; Helge Brattebø; Linköpings universitet; []
    Keywords : Environment; societal industrial ecology SIE ; reuse of construction materials; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Reuse is a measure for resource-saving materials and energy use, which is stressed in the concept of kretsloppsanpassning, or societal industrial ecology (SIE), as it will be termed in this thesis. Reuse is here used as a general term for any kind of reuse and divided into recirculation, upgrading and cascading, according to the degradation of the inner material structure. READ MORE

  5. 5. On the impact of temperature perturbations on the creep of sensitive clay

    Author : Yanling Li; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; thermal cycles; sensitive clays; oedometer tests; temperature; natural bonding; apparent preconsolidation pressure; multi-physics modelling; geothermal; static thermal loading;

    Abstract : Temperature affects the soil response, but is not fully understood and quantified and thus often ignored. The temperature fluctuations resulting from energy foundations and construction activities, such as excavations and soil stabilization, however, may lead to changes in the hydromechanical response of the clay.
