1. GEOPOLYMERS WITH GREEN LIQUOR DREGS : An investigation of the possibility tomanufacture a geopolymer based on residual streams
Master-uppsats, Umeå universitet/Kemiska institutionenSammanfattning : The pulp and paper industry make up a large part of the Swedish industry and is alsogrowing worldwide. With its growth, the amounts of residuals that are produced alsoincrease. The estimated annual global amount of residuals generated from pulp millsexceeds 1 million tons. LÄS MER
2. Evaluating the effective oxygen diffusion coefficient in blends of till and green liquor dregs (GLD) used as sealing layer in mine waste covers
Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : Dry covers can be used to limit the generation of acid mine drainage from sulphidic mine waste exposed to air and water. For the covers to act efficiently a high degree of saturation should be maintained in the cover, as the diffusion of oxygen is substantially reduced in water compared to that in air. LÄS MER
3. Changes in green liquor dregs after leaching with various acidic media
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Green liquor dreg (GLD) is a residual product that could be a solution to the problem with acid rock drainage. More information about how this material reacts and is affected when in contact with acid rock drainage (ARD) is needed. Different acidic media was used to investigate trace element leaching and the possible spectral changes using FTIR. LÄS MER
