16. Environmental assessment of incinerator residue utilisation
Sammanfattning : In Sweden, utilisation of incinerator residues outside disposal areas is restricted by environmental concerns, as such residues commonly contain greater amounts of potentially toxic trace elements than the natural materials they replace. On the other hand, utilisation can also provide environmental benefits by decreasing the need for landfill and reducing raw material extraction. LÄS MER
17. Mechanical properties of excavated sulfur rich soil stabilized with cement - A laboratory and field experiment
Sammanfattning : 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.

18. Life Cycle Assessment of Asphalt Pavements including the Feedstock Energy and Asphalt Additives
Sammanfattning : Roads are assets to the society and an integral component in the development of a nation’s infrastructure. To build and maintain roads; considerable amounts of materials are required which consume quite an amount of electrical and thermal energy for production, processing and laying. LÄS MER
19. Water powered percussive rock drilling : process analysis, modelling and numerical simulation
Sammanfattning : This thesis is devoted to problems, processes and systems related to the recently developed water powered percussive rock drilling method. The technology, which uses ordinary water to drive down-the-hole hammers, has been used to produce more than 6 million meters of blast holes within the mining industry. LÄS MER
20. Solubility of Np(IV), Zr(IV), and Reactive Transport Modeling with Uncertainty Calculations
Sammanfattning : Sweden, as some other countries, is planning to construct a repository for long-lived low and intermediate level radioactive waste. The planned repository is a concrete construction in the bedrock a few hundreds of meters below the surface. LÄS MER
