Standard Test Method for Flexural Strength of Concrete (Using Simple Beam With Center-Point Loading)

Significance and Use

This test method is used to determine the modulus of rupture of specimens prepared and cured in accordance with Practices C 31 or C 192. The strength determined will vary where there are differences in specimen size, preparation, moisture condition, or curing.

The results of this test method may be used to determine compliance with specifications or as a basis for proportioning, mixing and placement operations. This test method produces values of flexural strength significantly higher than Test Method C 78 (Note 1).

Note 1—The testing laboratory performing this test method may be evaluated in accordance with Practice C 1077.

Scope

1.1 This test method covers determination of the flexural strength of concrete specimens by the use of a simple beam with center-point loading. It is not an alternative to Test Method C 78.

1.2 The values stated in inch-pound units are to be regarded as standard. The SI equivalent of inch-pound units has been rounded where necessary for practical application.

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 and health practices and determine the applicability of regulatory limitations prior to use.
