DEFORMATION AND STRENGTH OF CONCRETE IN TENSION

It is suggested that the most pertinent difference between the various methods for testing concrete in tension, is the type of ideal stress regime produced. Tensile tests are divided into three categories on this basis, and the deformations in each are examined. It is concluded that the direct-pull test is the only means of determining the true tensile strength of concrete, and that even for linear elasto-brittle materials the strength obtained from the Brazilian, or splitting test, by the usual method of calculation, does not represent uniaxial tensile strength. The ring flexure test is shown to provide a simple means of determining the strain corresponding to maximum load- capacity in tension.
