The modulus of rupture is dependent on speciment size, moisture, curing, and preparation. We are confident that asgm have what you are looking for.
ASTM C78 Flexural Strength of Concrete Beams
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. Link to Active This link will always route to the current Active version of the 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.
Software for Series Systems. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. For the same specimen size, the strength determined will vary sstm there are differences in specimen preparation, curing procedure, moisture condition at time of testing, and whether the beam was molded or sawed to size.

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.
Email addresses must contain the symbol. 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. Next Checking to see if you are a returning visitor…. Historical Version s – view previous versions of standard. Results are calculated and reported as the modulus of rupture. Specimen geometry is in the form of a beam that is 6 x 6 inches with a minimum length of 21 inches.
Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static d78 and compression tests These dual column testers ast, available in both tabletop and floor standing models.

Combining values from the two systems may result in non-conformance with the standard. Partner Software automatically calculates the modulus of rupture based upon the maximum applied load and average dimensional values of the test specimen. Concrete, Asphalt and Rock.
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.
Flexural device according to ASTM C78
ASTM C78 addresses the flexural testing of concrete used in the construction of slabs and pavements with a “third-point” style flexure apparatus. WaveMatrix 2 for Dynamic Testing.
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. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!
