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

    Author : Nilla Olsson; Avdelningen för Byggnadsmaterial; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 12. Studies of moisture and alkalinity in self-levelling flooring compounds

    Author : Anders Anderberg; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkalinity; SLC; floor screed; moisture transport; self-levelling flooring compound; Material technology; diffusion coefficient; materialteknik; Materiallära; secondary emissions; sorption isotherm;

    Abstract : In recent decades there has been an increasing interest in the indoor environment and its connections with public health. One important topic discussed has been the relation between the moisture in buildings and health. Cementitious materials, when cast, contain excess water since this is necessary for workability and for flow properties. READ MORE

  5. 13. Transport and Sorption Phenomena in Concrete and Other Porous Media

    Author : Björn Johannesson; Göran Fagerlund; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Durability; Sorption; Capillary suction; Diffusion; Convection; Concrete; Byggnadsteknik; Mixture Theory; Building construction; Byggteknik; Civil engineering; Durability; Sorption; Capillary suction; Diffusion; Convection; Concrete; Byggnadsteknik; Mixture Theory; Building construction;

    Abstract : The work presented in this thesis is mainly focused on transport processes involved in service life predictions of concrete. Two papers and three reports deal with ion transport in pore solution of concrete. READ MORE

  6. 14. Moisture Conditions in High Performance Concrete. Mathematical Modelling and Measurements

    Author : Kristina Norling Mjörnell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; cement; relative humidity; desorption isotherm; moisture condition; moisture transport; high performance concrete; degree of reaction;

    Abstract : The work presented in this thesis has been focused on developing a model to calculate the moisture conditions in concrete of low water/binder ratio (W/B) which is normally used in high performance concrete. To do this, the moisture conditions in high performance concrete have been studied, from a very early age. READ MORE

  7. 15. Structure and Phase Stability of Polyelectrolyte-Macroion Solutions

    Author : Marie Skepö; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; hydrophobicity; spatially distributed interaction sites; protein-polymer interaction; Monte Carlo Simulations; redissolution; phase separation; cluster; complex; Polyelectrolytes; macroions;

    Abstract : Polyelectrolytes are polymers bearing ionisable groups, which, in polar solvents, can dissociate into charged polymer chains (polyelectrolytes) and small counterions. In aqueous solutions, polyelectrolytes interact strongly with other macroions and in particular they tend to associate with objects of opposite charge and form complexes. READ MORE
