6. The influence of ageing on the salt-frost resistance of concrete
Sammanfattning : Abstract This thesis presents the results of an investigation of the influence of ageing on the salt-frost resistance of concrete. The ageing mechanisms investigated were hydration, drying and carbonation. LÄS MER
7. Studies on the frost resistance of natural stone
Sammanfattning : This work deals with the effects of freeze-thawing on the deterioration of some types of natural stone, especially stones frequently used in old buildings in Sweden. Laboratory studies were performed mainly on Gotland sandstone. This stone has been widely used in old buildings in the whole Baltic region, and is often badly deteriorated. LÄS MER
8. Condensation and frost formation in fibrous thermal-insulation materials
Sammanfattning : Heavily insulated constructions are at present being used to strike at the vast energy consumption in residential buildings and commercial alike. They introduce a high-thickness layer of thermal insulation in the building envelopes. LÄS MER
9. Traditional lime mortar and plaster : Reconstruction with emphasis on durability
Sammanfattning : Lime mortar and plaster have been investigated with the aim to improve the knowledge on how to make them as durable as before the cement technology was developed. The background was the durability problems experienced for newly produced lime plaster on the medieval churches on the island of Gotland, Sweden. LÄS MER
10. Chloride Transport in Concrete under the Frost Action – An Experimental Study
Sammanfattning : Frost-induced ingress of chloride in concrete is one of the typical transport phenomena of aggressive substances when structures expose to severe environments such as marine tidal zone and de-icing highway in winter seasons. It is well known that Chloride ingress in concrete causes the reinforcement corrosion. LÄS MER
