  1. 1. Experimental studies of ion transport in cementitious materials under partially saturated conditions

    Författare :Nilla Olsson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :Cement; Bruk; Betong; Jontransport; Fukttransport; Sorptionsisoterm; Tillsatsmaterial; Kiselstoft; Masugnsslagg; Ciment; Mortier; Béton; Transport ionique; Transport d humidité; Sorption de vapeur d eau; Additions minérales; Fumée de silice; Laitier de haut fourneau granulé moulu; Cement; Mortar; Concrete; Ion transport; moisture transport; Water vapor sorption; Supplementary cementitious materials SCMs ; Silica fume; Ground granulated blast furnace slag;

    Sammanfattning : Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. LÄS MER

  3. 2. 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

  4. 3. Concrete slab on the ground and moisture control : verification of some methods to improve the moisture conditions in the foundation

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete slab; moisture; repair methods; ventilated foundation; drainage; numerical methods; grunder; grundplattor; platta på mark; betongplattor; fuktskador; reparationsmetoder; dränering; ventilerade konstruktioner; fukt; fukttransport; relativ fuktighet; temperatur; luftflöden; beräkningsmodeller; teori; fältundersökningar; mätresultat;

    Sammanfattning : This work deals with different types of repair methods for concrete slab on the ground damaged by moisture. Many of the available methods involve some kind of mechanical ventilation of the foundation. The basic principle for all these systems is the same. LÄS MER

  5. 4. Methods of measuring the moisture diffusivity at high moisture levels

    Författare :Mårten Janz; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fukttransport; materialegenskaper; permeabilitet; teori; beräkningsmetoder; mätmetoder; byggmaterial; forskningsresultat;

    Sammanfattning : The purpose of this licentiate study is to analyze capillarity transport in building materials, and in order to do that, develop a new measurement method by which the moisture diffusivity at high moisture levels can be measured in an easy way.... LÄS MER

  7. 5. Hydration, pore structure, and related moisture properties of fly ash blended cement-based materials : Experimental methods and laboratory measurements

    Författare :Oskar Linderoth; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Murbruk; Betong; Hydratation; Porstruktur; Sorption; Fukttransport; Mineraliska tillsatsmaterial; Flygaska; Cement; Mortar; Concrete; Hydration; Pore structure; Water vapour sorption; Moisture transport; Supplementary cementitious materials; Fly ash;

    Sammanfattning : Cement-based materials, such as mortar and concrete, are the most employed construction materials in the world. Cement is an important component; it reacts with water to form a glue, called cement paste, which causes the material to harden. Today, cement production accounts for a significant portion of the world’s annual carbon dioxide emissions. LÄS MER
