  2. 21. Studies of the efficiency of granulated blast furnace slag and limestone filler in mortars - long term strength and cloride penetration

    Author : Dimitrios Boubitsas; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; k-value; beständighet; durability; kloridinträngning; cement; limestone filler; bruk; långtidsegenskaper; kalksten; chloride diffusion; slagg; chloride migration; compressive strength; granulated blast furnace slag;

    Abstract : This report is the first part of the project Use of industrial by-products and filler in concrete - long term properties/durability. The aim is to improve the knowledge of long term properties/durability of cement and concrete produced using industrial by-products/fillers in order to promote an efficient, safe, reliable and increased use of such types of materials.

  4. 22. Leaching of concrete : experiments and modelling

    Author : Tomas Ekström; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; betongdammar; urlakning; dammar; beständighet; skador; laboratorieförsök; beräkningsmetoder; simulering; beräkningsmodeller;

    Abstract : Many concrete dams, and other concrete structures within the hydropower industry are old and in a more or less severe state of degradation. Leaching is, together with freeze-thaw, the most common degradation problem in Swedish hydraulic concrete structures. READ MORE

  5. 23. Leaching of concrete : the leaching process and its effects

    Author : Tomas Ekström; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material technology; water permeability.; concrete dams; byggnadsteknik; building construction; leaching; materiallära; materialteknik;

    Abstract : The present report presents an experimental study of leaching of concrete caused by water percolating through the concrete, or by diffusion from concrete to external water in contact. An apparatus was designed and constructed in which de-ionised water could be forced, by external pressure, through a number of concrete specimens of differing characteristics. READ MORE

  6. 24. Critical degrees of saturation at freezing of porous and brittle materials

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

    Abstract : 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. READ MORE

  7. 25. Rendered rainscreen walls - cavity ventilation, ventilation drying and moisture-induced cladding deformation

    Author : Jörgen Falk; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Over the past five years, moisture damages in external walls of wood frame structure and rendering on insulation as a cladding has been a widely debated subject which has received a lot of attention. In the light of this, the interest in an alternative construction method where rendering is applied on boards instead of insulation has increased. READ MORE
