Departamento de de Materiales Universidad Madrid, Madrid, Espana. tensile strength microconcrete aggregate 5mm) was measured using the cylinder and cube splitting test, influence two parameters - width of the load bearing strips the - were ascertained. It was found that the width strips greatly influences the splitting strength, a fact that is not reflected available analitycal or numerical results. Specimen size ( in the range of 50 to 300 has a negligible influence on the splitting strength, which thus shows no size-effect. Tensile strength, is a basic materials such as concrete, rocks crack nucleation propagation, so a ....

For these reasons alternative methods for measuring ft have been developed, of which one of the most relevant is the cylinder splitting strength, also called the Brazilian test. This test is based on the diametral compression of a cylinder. Its simplicity makes it one of the most universally employed and, for example, in the concrete field its use is normalized by a number of national standards such as the well known American ASTM-C496. The values obtained through this test compare well with those from flexural tests on three and four points, although the results are dependent on the size and shape of the specimen selected.
