Einfluß des Gefüges auf Haftung und Oberfläche von Gipsputzen
Abstract
Investigations on various gypsum plasters applied to different backrounds, more particularly by means of bond tensile strength measurements, scanning electron microscopy and stopping tests, yielded information on the dihydratetexture of plasters at interfaces, permitting an unambiguous interpretation of the processes involved. At the interfaces there are likely to be special dihydrate textures, which in general, however, have good bond with the interior of the plasters. With regard to the formation of this texture it must be ensured that no shear stresses can develop. This can be controlled by approriate adjustment of the degree of saturation of porous backgrounds and by means of admixtures to the plasters.
