Fiber-reinforced concrete is influenced in different ways by the amount and type of fibers in the concrete. 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 c109 ruler to ease specimen placement.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. We are c11609 that we have what you are looking for. Concrete – Control consoles for advanced testing: The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

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 5 — The results obtained using one size molded specimen may not correspond to the performance of larger or smaller molded specimens, concrete in large structural units, or specimens sawn from such units.

Iva Company info Privacy policy A specimen size different from the two preferred specimen sizes is permissible. These tests are significantly Note 1 Specimen toughness expressed in terms of the area awtm 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.

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. Glossary of Materials Testing Terms. 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.

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

Concrete – Flexural testing frames: Measurement of beam deflection and toughness This test is performed to assess the flexural performance and the residual resistance characteristics of fiber reinforced concrete FRC and shortcrete. 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.

In other cases, fibers may significantly increase the first-peak and peak strengths while affecting a relatively small increase in residual load capacity and specimen toughness at specified deflections.

Supporting rollers are able to rotate on their axes and are not placed in grooves or have other restraints that prevent their free rotation. The flexural tests in accordance with ASTM C are critical to ensure the concrete has the strength needed to properly support the shaft.
