ASTM WK73384

    New Test Method for Evaluating the Tensile Performance of Fiber-Reinforced Concrete Using Cylindrical Specimens with Double-Punch Loading

    (What is a Work Item?)

    Developed by Subcommittee: C09.42 | Committee C09 | Contact Staff Manager


    1. Scope

    1.1 This test method covers the determination of the peak tensile strength and post-crack capacity up to a specified deformation or circumferential tensile strain. In this test, a concrete cylinder is placed vertically between the loading platens of a test machine and compressed by two steel punches located concentrically on the top and bottom surfaces of the cylinder. The applied compression results in uniformly distributed, indirect tension along radial planes of the cylindrical specimen. The performance of specimens tested by this test method is quantified in terms of the initial stiffness, peak load, and residual strength at a specified deformation or circumferential tensile strain and crack widths. 1.2 This test method can be applied to plain concrete, fiber-reinforced concrete (FRC), high-performance fiber-reinforced concrete (HP-FRC), or ultra-high-performance fiber-reinforced concrete (UHP-FRC/UHPC) cylindrical specimens, such as molded cylinders and drilled cores. 1.3 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of international Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


    Double-punch Test, fiber-reinforced concrete, ultra-high-performance concrete, ultra-high-performance fiber-reinforced concrete, tensile test.


    Double-punch test is an indirect tensile test method and it shows much less variability then typical beam-type testing. It requires a very simple compression testing apparatus and much less time to perform. It only requires typical 6x12 in. concrete cylinders to perform the test. This method can be used for investigate various properties of FRCs such as strength, stiffness, ductility, mix quality.

    The title and scope are in draft form and are under development within this ASTM Committee.
