    • Comparative Life Cycle Assessment of Cotton and Other Natural Fibers for Textile Applications 

      La Rosa, Angela Daniela; Grammatikos, Sotirios (Journal article; Peer reviewed, 2019)
      Among natural fibers, such as cotton, silk, wool, flax, hemp, etc., cotton is the one that takes up the highest percentage in the textile market. Nevertheless, there are obstacles associated with its cultivation; it is ...

    • Nano-enabled polymers as embedded sensing electrodes in fibre-reinforced polymer composites 

      Dahl, Morten M.; Brøndbo, Vegar S. (Bachelor thesis, 2019)
      Polyuretan ble kombinert med nanoadditivene grafitt og karbon nanorør for å skape en elektrisk ledende elastomer, som videre ble implementert i en epoxy-karbonfiber kompositt for å gjøre bruken av karbonfiber-kompositter ...

    • Permeable nanomontmorillonite and fibre reinforced cementitious binders 

      Papatzani, S.; Grammatikos, Sotirios; Paine, K. (Journal article; Peer reviewed, 2019)
      Clinker reduction in cementitious binders is of paramount importance today, and nanotechnology has extended permissible limits. In the present study, a reference binder consisting of 60% Portland cement, 20% limestone, 20% ...

    • Prediction Models for Thermal Conductivity of Cement-based Composites 

      Hajmohammadian Baghban, Mohammad; Kioumarsi, Mahdi; Grammatikos, Sotirios (Journal article; Peer reviewed, 2018)
      This paper presents results from investigations on the long-term influence of concrete surface and crack orientation on ingress in cracks. Five reinforced concrete structures from Norway exposed to either de-icing salts ...

    • Pumpesump med integrert forankring 

      Josefsen, Henning; Pettersen, Liss-Anne N.; Skinlo, Marius Eilertsen (Bachelor thesis, 2019)
      Avløpspumpestasjoner brukes for å transportere avløps- og spillvann fra husholdninger, industri og annen virksomhet til avløpsrenseanlegg. Her blir avløpsvannet renset før vannet slippes tilbake til naturen. Pumpesumpen, ...

    • Utvikling av subsea støttekonstruksjon i polyuretan 

      Nielsen, Anders; Dokke, Gina; Jogerud, Antony (Bachelor thesis, 2019)
      EAB Engineering AS er produsent av blindflenser som benyttes til forsegling av sammenkoblingspunkter i undervannsinstallasjoner, eller som andre barriere for å hindre lekkasje av hydrokarboner i omgivelsene. Blindflensen ...
