DOUBLE-PUNCH TEST FOR TENSILE STRENGTH OF CONCRETE

The tensile strength of concrete is most commonly measured by the indirect split-cylinder test. Recently a new test, the double-punch test, has been proposed. The new test method had undergone preliminary experimental study to determine the testing procedure that would yield the most reliable and consistent results. However, further study was needed. By using the previously recommended procedure, the effect of several additional parameters on the tensile strength was studied. These parameters include the rate of stressing during the test and the effect of lightweight as well as regular concrete. The effects of the molds, machine lubricant, and testing machine are also being studied. Analysis of these results has led to a more thorough understanding and greater applicability of the new tensile test.
