Betongkonstruktioner för havsbaserade vindkraftverk : förstudie
- 2002
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Inom en snar framtid kommer många havsbaserade vindkraftverk troligen att byggas runt om Sveriges kuster. Det bör finnas ett behov av gemensamma regler eller tekniska lösningar inför en sådan byggnation så att vindkraftverken som helhet får en avsedd livslängd och små underhållskostnader.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- When decision on repair has been taken the available repair systems/methods must be evaluated with regard to the immediate requirements. For each type and cause of damage, there are normally only a few possible repair systems. These repair systems should be evaluated with regard to following 5 basic properties, or characteristics: 1) service life/durability, 2) structural stability/safety, 3) execution of work, 4) environmental effects, 5) economy/cost. Besides, factors of non-technical nature, such as disturbances of different kind during repair work, might have to be considered in the evaluation. It is desirable that the evaluation leads to quantitative results. It has however been realised that a quantitative assessment often is impossible to make due to lack of knowledge regarding underlying physical phenomenon and material properties. Hence, three different levels of evaluation have been suggested: 1) "Approved solution", 2) "Qualitative evaluation" and 3) "Quantitative evaluation".

Interlaboratory Comparison of the Measurement of Retention Curves
- 1999
-
Ingår i: Journal of Thermal Envelope & Building Science. - : SAGE Publications. - 1097-1963. ; 22:4, s. 334-348
-
Tidskriftsartikel (refereegranskat)abstract
- The results of an interlaboratory comparison of the measurement of apparent density, solid density, open porosity and retention curves are presented. Baumberger sandstone and Sander sandstone were used as test materials. Repeatability standard deviation and reproducibility standard deviation for the measurement of apparent density, solid density, open porosity and retention curve moisture content have been estimated from the results of the interlaboratory com parison. The statistical analysis was made along the guidelines given in ISO 5725-2.
