  7. 25. Studies of moisture and alkalinity in self-levelling flooring compounds

    Författare :Anders Anderberg; Avdelningen för Byggnadsmaterial; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
