  2. 1. Multiphysical analysis methods to predict the ageing and durability of concrete

    Author : Tobias Gasch; Anders Ansell; Richard Malm; Erik Nordström; Max Hendriks; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ageing; Cracking; Creep; Concrete; Durability; Finite Element Method; Multiphysics; Shrinkage; Beständighet; Betong; Finita elementmetoden; Krypning; Krympning; Multifysik; Sprickbildning; Åldring; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : With the societal demand for sustainability and the increasing age of infrastructure, a crucial task for the civil engineering community is to improve the durability of concrete structures. This thesis aims to contribute to such development through theoretical studies using mathematical modelling and numerical simulations. READ MORE

  4. 2. 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.

  6. 4. 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

  7. 5. Internal frost damage in concrete - experimental studies of destruction mechanisms

    Author : Katja Fridh; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tining; frysning; kallt klimat; frostskador skador; betong; materiallära; materialteknik; frost; ice formation; material technology; calorimetry; concrete; length change; upptining; fukt; beständighet; livslängd; forskning;

    Abstract : The aim of the study was to identify mechanisms acting at internal frost destruction of concrete. By 'internal frost destruction' is meant damage caused inside concrete that is moisture insulated from the surroundings, i.e. when no moisture exchange with the surroundings is possible during freeze-thaw.
