  1. 11. 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.

  4. 13. Moisture conditions in rain exposed wood joints - Experimental methods and laboratory measurements

    Författare :Maria Fredriksson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; moisture; durability; service life; microclimate; surface moisture; mositure content; Norway spruce; Picea abies; pressure plate; decay; growth ring width; heartwood;

    Sammanfattning : This thesis concerns the moisture conditions in rain exposed wood structures, i.e. wood exposed to high moisture levels. The focus was on the microclimate (the climate at the wood surface) and the material climate (the wood moisture content) in joints. LÄS MER

  5. 14. Interaction of water with supplementary cementitious materials: Hydration mechanism, microstructure and moisture transport

    Författare :Liming Huang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydration; moisture transport; Supplementary cementitious materials; electrical conductivity; formation factor; durability; microstructure;

    Sammanfattning : Supplementary cementitious materials (SCMs) offer a sustainable solution to reduce carbon emissions from the production of cement and concrete. This dissertation explores the impact of SCMs and the related additives on the hydration process of cementitious materials, which can affect their microstructure and transport properties. LÄS MER

  7. 15. 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
