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

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

    Abstract : 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. READ MORE

  4. 2. Mechanical properties of excavated sulfur rich soil stabilized with cement - A laboratory and field experiment

    Author : Alaleh Ziagharib; Christian Maurice; Josef Macsik; Qi Jia; Jan Laue; Bo Vesterberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sulfur-rich soil; Mixing; Sampling; Unconfined compressive strength; stabilization; Porosity; Water content; Consistency limits; Geoteknik; Soil Mechanics;

    Abstract : Sulfide soils are silty soils, often found in saturated conditions, under the groundwater level. Characteristics of these soils, including particle size distribution and consistency limits along with chemical composition and environmental properties, cause excavation to be necessary for construction purposes.

  5. 3. Composite Action and Confinement Effects in Tubular Steel-Concrete Columns

    Author : Mathias Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; connection; composite action; composite column; finite element analysis; bond; confined concrete; high-strength concrete; experiment; concrete-filled steel tube;

    Abstract : Composite columns composed of concrete-filled steel tubes (CFT) have become increasingly popular in structural applications around the world. This type of column can offer many advantages, for instance, high strength, ductility, and large energy absorption capacity, as well as increased speed of construction, positive safety aspects, and possible use of simple standardized connections.

  6. 4. Strength of Stabilised Soil - A Laboratory Study on Clays and Organic Soils Stabilised with different Types of Binder

    Author : Helen Åhnberg; Byggnadskonstruktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Hållfasthet; Geoteknik; Stabiliserad jord; materialteknik;

    Abstract : Stabilisation of soft soils by deep mixing with binders is the most frequently used method of ground improvement in Sweden today, and is increasingly being used internationally. The most common binders employed are cement and lime, but a variety of other binders may also be used for stabilisation of soils. READ MORE

  7. 5. Soil Modification by adding small amounts of binders : A laboratory study

    Author : Wathiq Jasim Al-Jabban; Jan Laue; Sven Knutsson; Nadhir Al-Ansari; Paolo Simonini; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Soil stabilization through addition of a hydraulic binder is a method frequently used to modify and improve engineering properties of soft soils. Additives like cement and lime are typically used as stabilizers. More recently, industrial by-products, such as fly ashes, cement kiln dust, blast furnace slags and other slags have been used.
