Flexural device according to ASTM C78 – FORM+TEST
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. Work Item s – proposed revisions of this standard.
ASTM C 78 C determines the flexural strength of concrete by the use of a simple beam with third-point loading. 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. C87 suggest reviewing the standard to fully understand the test set up, procedures, and result requirements.
ASTM C78 Flexural Bend Concrete Test Equipment
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. Bluehill LE for Basic Testing.
ASTM C78 addresses the flexural testing of concrete used in the construction of slabs and pavements with a “third-point” style flexure apparatus. 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.
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. 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. 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.
Subscribe to Instron News! We manufacture a variety of testing systems suitable for meeting this specification, including the common construction testing industry standard “compression-only” style systems.
