Email addresses can only contain letters, numbers and the following special characters: ASTM C78 addresses the flexural testing of concrete used in the construction of slabs and pavements with a “third-point” style flexure apparatus. Onsite Training At Your Facility.

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. We suggest reviewing the standard to fully understand the test set up, procedures, and result requirements. 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.

ASTM C78 Flexural Strength of Concrete Beams – Instron

Satisfies the c8 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. WaveMatrix 2 for Dynamic Testing. 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.

This standard is used in the testing of concrete in the construction of slabs and pavements. Software for Series Systems. The desired results are that modulus of v78 is calculated and the specimen fails within the middle third of the span length in the tension area or underside of the specimen.

ASTM C 78 C determines the flexural strength of concrete by the use of a simple beam with third-point loading.

Partner Software automatically calculates the modulus of rupture based upon the maximum applied load and average dimensional values of the test specimen. Work Item s – proposed revisions of this standard. It c788 used primarily in testing concrete for the construction of slabs and pavements. 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. We manufacture a variety of testing systems suitable for meeting this specification, including the common construction testing industry standard “compression-only” style systems.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part 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.

Concrete, Asphalt and Rock. 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.
