  1. 1. Paper-composite porcelain : characterisation of material properties and workability from a ceramic art and design perspective

    Detta är en avhandling från Göteborg : Göteborg University

    Författare :Kim Jeoung-Ah; Göteborgs universitet.; Gothenburg University.; [2006]
    Nyckelord :HUMANIORA; HUMANITIES; Ceramic art and design; Paper clay; Porcelain;

    Sammanfattning : Paper-composite porcelain is a type of paper clay which is made by combining any kind of porcelain with paper. Paper is added to clay to improve low green strength and plasticity - two of the main practical problems of working with porcelain. LÄS MER

  2. 2. Embankments founded on sulphide clay - some aspects related to ground improvement by vertical drains

    Detta är en avhandling från Stockhollm : KTH

    Författare :Rasmus Müller; Stefan Larsson; Göran Sällfors; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geotechnical engineering; embankments; vertical drains; sulphide clay; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap;

    Sammanfattning : In this thesis, some aspects concerning building embankments founded on sulphide clay are studied, with special reference to ground improvement by preloading in combination with prefabricated vertical drains (PVD’s). The main purpose of the research was to increase empirical knowledge of the mechanical behaviour of sulphide clays subjected to embankment loadings and of the interaction between vertical drains and sulphide clays.

  3. 3. The Unloading Modulus of Soft Soil: A Field and Laboratory Study

    Detta är en avhandling från Stockhollm : KTH

    Författare :Jenny Persson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swelling; heave; Clay; case study; excavation;

    Sammanfattning : Improved infrastructure in urban areas often necessitates underground construction, where the unloading behaviour of the soil is of importance for predicting the amount of heave and how long it will take for the soil to swell. It is of particular interest to study the need for the installation of tension piles, as well as whether the tunnel will be subjected to settlement or heave in the long term. LÄS MER

  4. 4. Flame-Retardant Cellulose Fibre/Fibril Based Materials via Layer-by-Layer Technique

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Oruc Koklukaya; Lars Wågberg; Gero Decher; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flame-retardant; cellulose fibre; cellulose nanfibril; layer-by-layer technique; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : According to an analysis conducted by the Swedish Chemicals Inspectorate in 2006, the approximate numbers of fire injuries per year in Sweden are 100 deaths, 700 major and 700 minor injuries.1 Observations also show that there has been an increase in the number of house fires during recent years.

  5. 5. Phosphorylated Cellulose Nanofibrils : A Nano-Tool for Preparing Cellulose-Based Flame-Retardant Materials

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Maryam Ghanadpour; Lars Wågberg; Jeffrey W. Gilman; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phosphorylated cellulose nanofibrils; flame-retardant; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The growing awareness of the need for a circular society and a circular chemistry has spurred the interest in using wood-based cellulose as a raw material for the preparation of new macroscopic devices and construction materials. The interest has been particularly focused on cellulose nanofibrils (CNF), which has led to the development of new material concepts through a nanoscale bottom-up engineering using renewable CNF.
