Results are calculated and reported as the modulus of rupture.

Give our test engineers a call today for help configuring the best test machine and accessories according to your standard. The modulus of rupture is dependent on speciment size, moisture, curing, and preparation. How can we help you?

We suggest referencing the instructions found 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. ASTM C78 addresses the flexural testing of concrete used in the construction of slabs and pavements with a “third-point” style flexure apparatus.

Concrete, Asphalt and Rock. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. 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.

The DX is a servo-controlled system, which allows the test to perform automatically within a closed loop. Subscribe to Our Newsletters.

We are confident that we have what you are looking for. For the same specimen size, the strength determined will vary if there are differences in specimen preparation, curing 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 f78 systems because of the more consistent control of the loading rate and wstm less risk of shock to the specimen.
