A GENERAL RELATION BETWEEN TENSILE STRENGTH AND SPECIMEN GEOMETRY FOR CONCRETE-LIKE MATERIALS

In the course of this study, a general relation between the different tensile strengths of concrete-like materials was established, which is based on the "weakest link" concept. Seven mortar mixtures were tested under nine different conditions of tensile tests: bending test with axial load and with load applied on the middle third of the specimen, splitting tensile tests on samples of different sizes and direct tensile tests. In each case, the volume of material with a tensile stress more than 0.95 of the maximum stress within the sample (maximum stress volume) was evaluated. A decreasing linear relation between the ultimate tensile strength logarithm and the maximum stress volume logarithm was found with a gradient that can be regarded as constant for the seven mixtures tested. /TRRL/
