  1. 1. Retarded sorption in wood : experimental study, analyses and modeling

    Författare :Håkan Håkansson; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; transient; non-linear model; swelling-shrinkage; latent heat effect; history-dependent sorption; anomalous sorption; non-Fickian; retarded sorption; measurements; moisture; wood; Byggnadsteknik;

    Sammanfattning : Models of moisture flow processes in wood are normally based on a Fickian approach. In many instances, there are considerable discrepancies between modelling and experimental results. It is shown in this thesis that a major cause for these discrepancies is a so-called retarded sorption which is not accounted for in conventional theories. LÄS MER

  2. 2. Experimental studies of sorption and transport of moisture in cement based materials with supplementary cementitious materials

    Författare :Mahsa Saeidpour; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Concrete; Moisture transport; Hysteresis; Supplementary cementitious materials; Water vapor sorption; Sorption isotherms; Anomalous sorption;

    Sammanfattning : Most deterioration processes in cement based materials are closely related to moisture sorption and moisture transport properties. Therefore, it is important to study these properties, both theoretically and practically. This work is an experimental investigation in this field. LÄS MER
