    Nyckelord :karbonatisering; accelerated carbonation; SCMs; cement paste; carbonation depth;

    Sammanfattning : Concrete structures have the largest surface area of all human made structures. Large surface area makes concrete capable to absorb CO2 from environment during its lifetime. It is estimated that concrete during its lifetime can absorb about 15-20% of CO2 which had produced in cement production. LÄS MER

  3. 2. Koldioxidupptag i betong : Accelererade laboratorieförsök

    Master-uppsats, KTH/Betongbyggnad

    Nyckelord :accelererad karbonatisering; betong; flygaska; kolioxidupptag;

    Sammanfattning : Concrete absorbs carbon dioxide from air by a process called carbonation. The process takes a long time to get substantial results in natural conditions. Because of this an accelerated carbonation method is used. During accelerated carbonation the level of carbon dioxide is much higher than in natural air. LÄS MER

    Sammanfattning : It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass. LÄS MER
