Load ratings up to kN 56, lbf Base lengths up to mm 48 in Various roller sizes available Available in 3-point and 4-point configurations. Next Checking to see if you are a returning visitor…. 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.

Email addresses must contain the symbol. ASTM C78 addresses the flexural testing of concrete used in the construction of slabs and pavements with a “third-point” style flexure apparatus. How can we help you?

The modulus of rupture is dependent on speciment size, moisture, curing, and preparation. We use cookies to awtm your browsing experience.

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.

We manufacture a variety of testing systems suitable for meeting this specification, including the common construction testing industry standard “compression-only” style systems.

Subscribe to Our Newsletters. 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. 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.

Have a question about conducting the test for this standard? Work Item s – proposed revisions of this standard. Bluehill LE for Basic Testing. The DX is a servo-controlled system, which allows the test to perform automatically within a closed loop.

Partner Software automatically calculates the modulus of rupture based upon the maximum applied load and average dimensional values of the test specimen. Historical Version s – view previous versions of standard. 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.

Combining values from the two systems may result in non-conformance with the standard. By continuing to use our site, you accept our cookie policy.
