Glossary of Materials Testing Terms. The desired results are that modulus of rupture is calculated and the specimen fails within the middle third of the span length in the tension area or underside of the specimen.

Flexural device according to ASTM C78
Combining values from the two systems may result in non-conformance with the standard. Load ratings up to kN 56, lbf Base lengths up to mm 48 in Various roller c778 available Available in 3-point and 4-point configurations.
We suggest reviewing the standard to fully understand the test set up, procedures, and result requirements. Universal materials testing software for static hydraulic, electromechanical and torsion testing systems – WBB.

ASTM C 78 C determines the flexural strength of concrete by the use of a simple beam with third-point loading. By means of our testing expertise and modular product design, we will help find the solution that is right for you.
We are confident that we have what you are looking for. Subscribe to Our Newsletters. We manufacture a variety of testing systems suitable for meeting this specification, including the common construction testing industry standard “compression-only” style systems. The DX is a servo-controlled system, which allows the test adtm perform automatically within a closed loop. For the same specimen size, the strength determined will vary if there are differences in specimen zstm, curing procedure, moisture condition at time of testing, and whether the beam was molded or sawed to size.
Specimen geometry is in the form of a beam that is 6 x 6 inches with a minimum length of 21 inches. Partner Software automatically calculates the modulus of rupture based upon the maximum applied load and average dimensional values of the test specimen.

This standard is used in the testing atm concrete in the construction of slabs and pavements. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. We suggest astj the instructions asstm in the ASTM C78 for the loading rates, proper specimen orientation, and application of preload to assure “gap-free” contact between the specimen and fixture.
It is used primarily in testing concrete for the construction of slabs and pavements. 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 modulus of rupture is dependent on speciment size, moisture, curing, and preparation.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
