ASTM C78 Flexural Strength of Concrete Beams – Instron
We manufacture a variety of testing systems suitable for meeting this specification, including the common construction testing industry standard “compression-only” style systems. 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. Partner Software automatically calculates the modulus of rupture based upon the maximum applied load and average dimensional values of the test specimen.
WaveMatrix 2 for Dynamic Testing. Combining values from the two systems may result in non-conformance with the standard.
Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests Axtm dual column testers are available in both tabletop and floor asm models. Satisfies the requirements of both ASTM C and C78 Rated to kN 22, lbf Loading span attached to a spherical seat to maintain proper alignment Includes preinstalled metric ruler to ease specimen placement.

Flexural device according to ASTM C78
Specimen geometry is in the form of a beam that is 6 x 6 inches with a minimum length of 21 inches. Description Literature Contact Us ASTM C78 addresses the flexural testing of concrete used in the construction of slabs and pavements with a “third-point” style flexure apparatus.
The desired results are that modulus of rupture is wstm and the specimen fails within the middle third of the span length in the tension area or underside of the specimen. This standard is used in the testing of concrete in the construction of slabs and pavements.
Historical Version s – view previous versions of standard. For the same specimen size, the strength determined will vary if there are differences in specimen preparation, d78 procedure, moisture condition at time of testing, and whether the beam was molded or sawed to size. We find that operators prefer this style of system over manually controlled systems because of the more consistent control of the loading rate and the less risk of shock to the specimen.
How can we help you? Results are calculated and reported as the modulus of rupture. ASTM C 78 C atsm the flexural strength of concrete by the use of a simple beam with third-point loading.
