Critical degrees of saturation at freezing of porous and brittle materials
- 1973
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis is based on experimental work carried out during the period 1968-1972. The whole investigation is sponsored by the Swedish Council for Building Research and has been performed at the department of Building Materials at the Lund Institute of Technology. The thesis treats the problem frost resistance of building materials, a problem which is far from beeing solved despite much scientific work in many countries. According to the author the main reason for this lack of success is, that the problem of frost resistance is not only a function of materials properties but also of properties of the environment in which the materials are used. Hence, in order to solve the problem it is necessary to investigate separately the effect of material properties and the effect of environmental properties on the frost resistance of a material...

Degre critique de saturation. Un outil pour l'estimation de la resistance au gel des materiaux de construction

Tidskriftsartikel (refereegranskat)abstract
- It was proved theoretically and empirically that critical degrees of saturation exist in connection with freezing of porous and brittle materials of different types. It was also proved that damage occurs after one freezing if the actual degree of ssaturation exceeds the critical. Comparisons between the critical degrees of saturation of different materials and those reached in practice in a given situation provide a possibility of choosing materials with regard to frost resistance.

Determination of pore size distribution by suction porosimetry
- 1973
-
Ingår i: Matériaux et Constructions. - 0025-5432. ; 6:33, s. 191-201
-
Tidskriftsartikel (refereegranskat)abstract
- The theory and practice of suction porosimetry methods (suction plate, pressure membrane and centrifuge) are reviewed together with related methods based on the rate of penetration of wetting liquids, and on static and dynamic fluid/fluid displacement measurements.

Determination of pore-size distribution from freezing-point depression
- 1973
-
Ingår i: Materials and Structures. - 1359-5997. ; 6:33, s. 215-225
-
Tidskriftsartikel (refereegranskat)abstract
- By utilising the effect of interfacial curvature on the freezing-point of liquids confined in capillaries, it is in principle possible to determine a pore-size distribution, from the curve of freezing-point against volume frozen. The method is formally similar to capillary condensation methods based on the Kelvin equation. Suitable experimental techniques are described. A comparison with the results of mercury porosimetry on a sample of brick shows reasonable agreement.

Determination of specific surface by the BET method
- 1973
-
Ingår i: Matériaux et Constructions. - 0025-5432. ; 6:33, s. 239-245
-
Tidskriftsartikel (refereegranskat)abstract
- The theoretical background of the adsorption isotherm equation of Brunauer, Emmett and Teller is reviewed, together with the experimental techniques available for measuring physical adsorption of gases by solids. Examples are given to show how such measurements are used to determine the specific surface of constructional materials.
