1. 1. Characterisation of residues : Release of contaminants from slags and ashes

   Författare :Ann-Marie Fällman; Rob N.J. Comans; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Residues from industrial processes as well as from energy production utilities have in many cases properties similar to geological materials. They can be used as filling and construction materials if the net environmental impact and the technical properties are acceptable. LÄS MER

3. 2. Critical degrees of saturation at freezing of porous and brittle materials

   Författare :Göran Fagerlund; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resistance; freezing mechanism; freezing test method; pore size distribution determination ; saturation degree of ; water absorption; frost;

   Sammanfattning : This thesis is based on experimental work carried out during the period 1968-1972. The whole investigation is sponsored by the Swedish Council for Building Research and has been performed at the department of Building Materials at the Lund Institute of Technology. LÄS MER

4. 3. Maturation of Clay Seals in Deep Bore Holes for Disposal of Radioactive waste : Theory and Experiments

   Författare :Ting Yang; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-level radioactive waste; HLW; very deep borehole; VDH; disposal; saturation degree; water transport; maturation; model; shear strength; hydraulic conductivity; swelling pressure; homogenization; Geoteknik; Soil Mechanics;

   Sammanfattning : KBS-3 and very deep borehole (VDH) concepts are two major types of long-term geologicaldisposal methods for high-level radioactive waste (HLW) isolating from the biosphere. TheKBS-3V concept for isolating the HLW at the depth of 400-500 m, is the officially proposedoption in Sweden and has been the subject of considerable research in the past few decades,while the VDH concept was considered as an option in the 1950s but later became discouragedbecause of insufficient experience in drilling technology.

5. 4. Dimensional Stability of Paper : Influence of Fibre-Fibre Joints and Fibre Wall Oxidation

   Författare :Per A. Larsson; Lars Wågberg; Mikael Lindström; Lars Berglund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Sammanfattning : Papper är ett mycket mångsidigt material. Trots detta finns det ett flertal egenskaper som begränsar papperets användbarhet. Ett av de större problemen med cellulosa- och lignocellulosafibrer är att de sänker sin fria energi genom att sorbera vatten, och denna sorption förändrar papperets dimensioner. LÄS MER

7. 5. Impregnation of concrete structures : transportation and fixation of moisture in water repellent treated concrete

   Författare :Anders Johansson; Johan Silfwerbrand; Lars-Olof Nilsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

   Sammanfattning : Water repellent agents, today mainly consisting of alkylalkoxysilanes, are often used on concrete to prolong the service life of the structure. This is accomplished by protecting the reinforcement bars from chlorides or by changing the moisture content inside. LÄS MER
