1. Stabilization of fine-grained soils in cold environment and exposed to seasonal frost : By-products as hydraulic binders
Sammanfattning : This doctoral thesis deals with the stabilization of ﬁne-grained soils using by-product originated hydraulic binders. The use of ﬁne-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. LÄS MER
Sammanfattning : Recent grouting projects in Sweden have concentrated on the grout itself. The only grout normally used in Sweden is a cement-based one. During the past 10 years, the acceptable flow of water into tunnels has been significantly reduced. The current requirements mean that an average fracture aperture of around 0. LÄS MER
Sammanfattning : The implementation of the EC directive concerning landfill liners and covers sets stricter technical and environmental requirements for landfill barriers. It is therefore essential to identify suitable materials that fulfil these requirements. LÄS MER
Sammanfattning : Since the first introduction of thermal response tests with mobile measurement devices in Sweden and USA in 1995, the method has developed and spread in North America and Europe. Thermal response tests have so far been used primarily for in situ determination of design data for BHE (borehole heat exchanger) systems, but also for evaluation of grout material, heat exchanger types and groundwater effects.

Sammanfattning : The aim of this study was to develop an understanding of the fluid properties that influence the efficiency of hydraulic systems in a steady-state, especially components in hydrostatic transmission systems under different running conditions. The aim has also been to investigate and model the sources of losses in hydraulic machines, in order to estimate the losses, taking fluid properties into account. LÄS MER
