ABSTRACT: Thick deposits of fine-grained marine sediments exist in large areas of western Greenland. Many places these sediments are located above sea-level, and now complicate construction projects in urban areas. The mineralogy of the fine-grained sediments is very different from European sediments, mainly due to the cold climate, and it is therefore of great interest to study possible methods to improve the stability and strength properties. This project includes laboratory studies of lime stabilization on fine-grained marine sediments from Kangerlussuaq, western Greenland. The results have included tests to determine the optimum lime content and the strength development in relation to both reaction time and curing temperature. Hopefully the results from this project will lead to a future use of lime stabilization and make it possible to use/reuse materials of poor quality at construction sites in Greenland.

RÉSUMÉ: Des dépôts épais de sédiments marins fins existent dans des vastes régions du Groenland de l'Ouest. A beaucoup d'endroits ces sédiments se trouvent au-dessus du niveau de la mer et compliquent maintenant les projets de construction dans les zones urbaines. La minéralogie des sédiments fins est très différente des sédiments européens, améliorer les propriétés de stabilité et de résistance. Ce projet comprend des études de laboratoire de stabilisation de la chaux sur les sédiments marins fin de Kangerlussuaq dans l'ouest du Groenland. Les résultats ont compris des tests pour déterminer le contenu optimal de chaux et le développement de la résistance par rapport aux temps de réaction et la température de durcissement. Espérons que les résultats de ce projet mèneront à une utilisation future de stabilisation de la chaux et permettent d'utiliser / réutiliser des matériaux de mauvaise qualité sur les chantiers du Groenland.
