11. Experimental studies of ion transport in cementitious materials under partially saturated conditions
Sammanfattning : Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. LÄS MER
12. Putsens inverkan på fasadens fuktbalans
Sammanfattning : The report deals with the effect of renderings on the moisture balance in facades. The main therne is the moisture mechanism in cnnnection with different moisture sources. Different opinions about moisture in facades and consequences of moisture are mentioned as a background. LÄS MER
13. Water Absorption in Two-Layer Masonry Systems - Properties, profiles and predictions
Sammanfattning : The main impetus for this research was the desire to verify models for determining transient moisture profiles in the capillary range. For the evaluations, transient moisture profiles were both simulated and measured, after which the results of the two methods were compared. LÄS MER
14. Redistribution of moisture and ions in cement based materials
Sammanfattning : There were two principal objectives for this thesis. The first was to develop a methodology and evaluation model of moisture redistribution in order to make the future relative humidity in a screeded concrete slab predictable. The second objective was to develop a method to determine the critical humidity for ion transport in concrete. LÄS MER
15. Moisture Conditions and Frost Resistance of Concrete in Hydraulic Structures
Sammanfattning : Owing to the winter conditions in Sweden, the effects of frost action may have a considerable impact on the deterioration of concrete. Both superficial and internal damage, which are suspected to have been caused by frost action, have been found in concrete in hydraulic structures. LÄS MER
