(Test Method)Standard Test Method for Splitting Tensile Strength of Cylindrical Concrete Specimens
Standard Test Method for Splitting Tensile Strength of Cylindrical Concrete Specimens
SIGNIFICANCE AND USE
5.1 Splitting tensile strength is generally greater than direct tensile strength and lower than flexural strength (modulus of rupture).
5.2 Splitting tensile strength is used in the design of structural lightweight concrete members to evaluate the shear resistance provided by concrete and to determine the development length of reinforcement.
SCOPE
1.1 This test method covers the determination of the splitting tensile strength of cylindrical concrete specimens, such as molded cylinders and drilled cores.
1.2 The 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 non-conformance with the standard.
1.3 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.
1.4 The text of this standard references notes that provide explanatory material. These notes shall not be considered as requirements of the standard.
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.

4. Summary of Test Method
4.1 This test method consists of applying a diametral compressive force along the length of a cylindrical concrete specimen at
a rate that is within a prescribed range until failure occurs. This loading induces tensile stresses on the plane containing the applied
load and relatively high compressive stresses in the area immediately around the applied load. Tensile failure occurs rather than
compressive failure because the areas of load application are in a state of triaxial compression, thereby allowing them to withstand
much higher compressive stresses than would be indicated by a uniaxial compressive strength test result.
4.2 Thin, plywood bearing strips are used to distribute the load applied along the length of the cylinder.
