At the option of the specifier of tests, it provides for determination of specimen toughness based on the area under the load-deflection curve up to a prescribed deflection see Note 1. Contact Us View Accessories Catalog. Maintenance Spares Technical trainings Warranty Academy. 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.

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. Universal, open structure flexural frame, kN cap.

The standard also specifies that the test must be performed in servo control at very slow deflection rates with servo feedback from the average of two deflection sensors placed on either side of the specimen.

It also requires determination of residual loads at specified deflections, the corresponding residual strengths calculated by inserting them in the formula for modulus sstm rupture given in Eq 1 see Note 1.

A specimen size different from the two preferred specimen sizes is permissible.

The purpose of ASTM C is to not only determine the peak strength of the concrete but also to find the residual strength from the fibers after the first crack appears. Note 1 Residual strength is not a true stress but an engineering stress computed using simple engineering bending theory for linear elastic materials and gross uncracked section properties.

The appropriateness of each parameter depends on the nature of the proposed application and the level of acceptable cracking and deflection serviceability. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!

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 axtm increase of deflection.

Repair Services and Parts. 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. Work Item s – proposed revisions of this standard.

In some cases, fibers may increase the residual load and toughness capacity at specified deflections while producing a first-peak strength equal to or only slightly greater than the flexural strength of the concrete without fibers.

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.

Active view current version of standard. Subscribe to Instron News! 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. 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.

These tests are significantly The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Flex Testing of Fiber Reinforced Concrete to ASTM C1609-10

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.

FRC can also significantly lower materials and labor costs compared to rebar or wire mesh reinforced concrete.

The absolute values of energy absorption obtained in this test are of little direct relevance to the performance of fiber-reinforced concrete structures asrm they depend directly on the size and shape of the specimen and the loading arrangement. Ensure that there is enough travel for them to record the sample deflection at the mid-point. Figure 1 shows a typical test setup to perform the C test. Follow us YouTube LinkedIn.
