    Sammanfattning : The interest for lignocellulose biomass has grown strongly in the last decades due to its potential to substitute fossil fuels. Pre-processing of biomass is of-ten needed to enable utilization of its full potential. A common pre-processing step is milling where the biomass is fractionated into wood powder usable for e.g. LÄS MER

  5. 24. Optimisation of hollow core slabs : Producing units of a smaller standard width

    Master-uppsats, KTH/Byggvetenskap

    Författare :Konstantinos Apostolou; [2020]
    Nyckelord :;

    Sammanfattning : The Swedish precast concrete company ‘Strängbetong’ produces a variety of Hollow Core slabs, with a standard width of 1200 mm. Quite often, the HC units are subjected to longitudinal cutting1, which takes place in the factory by a diamond blade, in order to achieve narrower elements. LÄS MER
