1. Optimization of a one-part geopolymerization method for lab-scale, using waste glass wool as a precursor
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Geopolymers are amorphous inorganic polymeric structures. They are used as binding agents and can be compared to cementitious materials such as ordinary Portland cement. This thesis aims to produce geopolymers from waste glass wool. Today glass wool is found in isolation, both thermal and sound insulation, and it is not being recycled. LÄS MER
2. An investigation of the interactions between clay nanoplatelets in the presence of monovalent and divalent salts, as well as cationic peptides utilising atomistic molecular dynamics
Master-uppsats, Lunds universitet/Kemiska institutionenSammanfattning : Clays are negatively charged nanoplatelets with a layered silicate structure. It has been observed from small angle X-ray scattering measurements, and coarse-grained molecular dynamics simulations (CG-MD) that clay nanoplatelets are able to form stacks, known as tactoids, in the presence of divalent or multivalent counterions [8, 5].

3. Flotation of Yxsjöberg historical tungsten ore tailings
Master-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgiSammanfattning : Tailings dams, due to their sheer size and metal content, pose safety and environmental hazards. The Småltjarnen repository, which hosts material from the largest known tungsten mineralization in Sweden named the Yxsjöberg deposit, is estimated to contain 2. LÄS MER
4. Evaluation of long-term performance of sodium silicate grouted in embankment dams
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : Embankment dams is the most common type of dams in operation inSweden today. Due to the nature of embankment dams, seepage throughthem will always occur. If the seepage velocity exceeds a critical velocity,internal erosion is initiated, which could lead to damage in form of pipingand sinkholes. LÄS MER
5. Effects of Fly Ash on the properties of Alkali Activated Slag Concrete
Master-uppsats, Luleå tekniska universitet/GeoteknologiSammanfattning : This master thesis presents the effects of fly ash on the properties of alkali activated slag concrete, commonly referred as Geopolymer concrete (GPC). Cement manufacturer are major producers of CO2 which negatively affects the environment. LÄS MER
