  1. 11. Stabilization-solidification of high water content dredged sediment : Strength, compressibility and durability evaluations

    Författare :Gregory Makusa; Kauko Kujala; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. LÄS MER

  4. 13. Recycling of concrete in new structural concrete

    Författare :Madumita Sadagopan; Andrzej Cwirzen; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete recycling; sustainability; closed-loop recycling; recycled aggregates; compressive strength; workability mechanical pre-processing; secondary cementitious materials; green concrete; climate-optimized concrete; Resource Recovery; Resursåtervinning;

    Sammanfattning : Concrete waste as crushed concrete aggregates (CCA) in structural concrete gives a new purpose and prolongs the technical life of the reference concrete accomplishing closed loop recycling. This research investigates CCA as aggregate replacement in an industrial reference concrete recipe as fine aggregate fractions and overall aggregate replacement. LÄS MER

  5. 14. Preventing Acid Rock Drainage Formation from Sulfidic Waste Rock Using Secondary Raw Materials

    Författare :Elsa Nyström; Lena Alakangas; Andrzej Cwirzen; Christian Maurice; Jose Miguel Nieto; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geochemistry; Tillämpad geokemi;

    Sammanfattning : One of the central and most challenging environmental problems related to mining is acid rock drainage (ARD) formation. The drainage is characterized by low pH and elevated concentrations of sulfate, metals, and metalloids formed when sulfide-bearing minerals are subjected to oxygen and water. LÄS MER
