A mining company in the southwestern United States needed to test fiber reinforced concrete shotcrete used to line the mine shafts in a new copper mine. This test method may c109 used for comparison of mixtures, quality control, and research and development. 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.
Moreover, structural members of significantly different thickness experience different maximum crack widths for a given mid-span deflection with the result that fibers undergo different degrees of pull-out and extension.

Partner software with the GenTest module provided the flexibility to adjust servo control parameters throughout the test to ensure the test ran with no problems under all conditions.
Link to Active This link will always route to the current Active version of the standard. ASTM C determines the flexural performance of fiber-reinforced concrete using parameters derived from the load-deflection curve obtained by testing a simply supported beam under third-point loading using a closed-loop, servo-controlled testing system.
ASTM C1609 Fiber-Reinforced Concrete Flexural Test Equipment
A specially configured universal test machine capable of servo-controlled operation is used with the net deflection of the center of the beam measured and used to control the rate of increase of deflection. The console is supplied Note 5 — The results obtained using one size molded specimen may not correspond to the performance of larger aetm smaller molded specimens, concrete in large structural units, or specimens sawn from such units. The absolute values of energy absorption obtained in this test are of little direct relevance to the performance of fiber-reinforced concrete structures since they depend directly on the size and shape of the specimen and the loading arrangement.
Note 1 Specimen toughness expressed in terms of the area under the load-deflection curve is an indication of the energy absorption capability of the particular test specimen, and its magnitude depends directly on the geometry of the test specimen and the loading configuration.
Have a question about conducting the test for this axtm Universal, open structure flexural frame, kN cap. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more! Specimen toughness is a measure of the energy absorption capacity of the test specimen. It provides for determination of specimen toughness based on the area under the load-deflection curve up to a prescribed deflection see Note 2 and the corresponding equivalent flexural strength ratio.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 2 1c609 Specimen toughness expressed in terms of the area under the load-deflection curve is an indication of the energy absorption capability of the particular test specimen, and its magnitude depends directly on the ashm of the test specimen and astn loading configuration.
It also requires determination of residual loads at specified deflections, and the corresponding residual strengths calculated by inserting them in the formula for modulus of rupture given in Eqn. Work Item s – proposed revisions of this standard.
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.
