ASTM C293

Full Name

ASTM C293 – Standard Test Method for Flexural Strength of Concrete (Using Simple Beam With Center-Point Loading)

Scope

ASTM C293 covers the determination of the flexural strength of concrete specimens by applying a load at the center of a simply supported beam.

The standard addresses:

  • Specimen preparation: outlines the procedures for preparing concrete specimens in accordance with ASTM C31 (field) or ASTM C192 (laboratory) practices.
  • Test setup: describes the apparatus and setup required for the test, including a testing machine, loading apparatus, support system, and deflection-measuring device.
  • Loading procedure: details the application of the load at the center of the specimen until failure occurs.
  • Calculation of flexural strength: provides the formula for calculating the flexural strength (modulus of rupture) of the concrete based on the maximum load and specimen dimensions.
  • Reporting requirements: specifies the information that should be included in the test report, such as the average flexural strength, individual specimen results, and any deviations from the standard procedure.

ASTM C293 is primarily used for:

  • Quality control: assessing the flexural strength of concrete to ensure it meets the specified requirements for a particular project.
  • Research and development: investigating the flexural behavior of concrete under different conditions and with varying mix designs.
  • Comparative testing: comparing the flexural strength of different concrete mixtures or evaluating the effect of different curing conditions.

It is important to note that ASTM C293 is just one of several test methods available for measuring the flexural strength of concrete. Other common methods include ASTM C78, which uses a third-point loading configuration.
