  1. 6. On Mesoscale Modelling of Coupled Chloride-Moisture Transport in Concrete

    Författare :Filip Nilenius; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coupled diffusion; concrete; moisture; mesoscale; chloride ions.; Multiscale modelling; computational homogenization;

    Sammanfattning : The service life behaviour of concrete structures is highly influenced by the ingress of chloride ions. At sufficiently high concentrations, chloride ions can initiate corrosion of embedded reinforcement bars, which may substantially reduce the structure's bearing capacity and ultimately lead to structural collapse.

  3. 7. Moisture Transport and Moisture-Induced Distortions in Timber - an Experimental and Numerical Study

    Författare :John Eriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat transfer; gluing; twist; drying; wood; timber board; laminated product; FEM; distortion; moisture; mass transfer;

    Sammanfattning : Timber products subjected to climatic variations commonly display moisture-induced distortions that can lead to serious problems for end-users. The aim of the thesis, which consists of an extended summary and six appended papers, was to investigate the potential of using the gluing technique suggested here for dealing with problems of moisture-induced distortions and developing the heat and mass transfer models which such distortion analyses require.

  4. 8. Moisture properties of self-levelling flooring compounds

    Författare :Anders Anderberg; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fukttransport; secondary emissions; SLC; alkali; self-levelling; moisture transport; diffusion coefficient; självnivellerande golv; flooring screed; fuktegenskaper; flooring compound; sorption isotherm;

    Sammanfattning : Self-levelling flooring compounds (SLC) are used to level substrates (mainly concrete slabs) before applying final floor coverings. Although it is an extensively used product, only limited research has so far been published concerning their moisture properties. LÄS MER

  7. 10. Investigations on moisture damage-related behaviour of bituminous materials

    Författare :Umaru Bagampadde; Ulf Isacsson; Manfred Partl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture damage; State-of-the-Art; Stripping; Moisture sensitivity; Bituminous materials; Construction engineering; Konstruktionsteknik;

    Sammanfattning : This doctoral thesis presents results of literature review on classical and contemporary aspects of stripping, as well as experimental investigations on moisture damage as influenced by bituminous materials. Previous research in the area of moisture damage was reviewed and synthesized into a state-of-the-art. LÄS MER
