Abstract
Authores have been studied about the shearing strength of mortar and concrete for few years. In many cases, the rupture of these brittle materials become separation rupture by tensile stress, but no sliding rupture. Only, under the case of compressive stress condition, the phenomenon such as sliding rupture or shearing rupture will occur. In this paper, we describe the strength of cylindrical specimen made of cement mortar which is compressed in a ring on the surface of specimen, and the apparent slip shearing strength as a result of above experiments. First, we describe the outline of the elastic solution of cylindrical specimen subjected to partial compressive force shown in Fig.-1 to analyze this phenomena, secondly, the slip rupture line given the same elastic solution, in this paper (No.1).
