Active view current version of standard. Other Historical Standards. Work Item s - proposed revisions of this standard. More C It also requires determination of residual loads at specified deflections, the corresponding residual strengths calculated by inserting them in the formula for modulus of rupture given in Eq 1 see Note 1. 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.
A specimen size different from the two preferred specimen sizes is permissible. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
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.

Scope 1. 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. Note 2 — 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.

How to Perform ASTM C1609 Concrete Bend Strength Testing
Historical Version s - view previous versions of standard. Work Item s - proposed revisions of this standard. More C Specimen toughness is a measure of the energy absorption capacity of the test specimen. The appropriateness of each parameter depends on the nature of the proposed application and the level of acceptable cracking and deflection serviceability.

ASTM C1609 Fiber-Reinforced Concrete Flexural Test Equipment
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. The first-peak strength, peak strength, and residual strengths determined by this test method reflect the behavior of fiber-reinforced concrete under static flexural loading. This test method may be used for comparison of mixtures, quality control, and research and development. The loading and specimen support system is capable of applying third-point loading to the specimen without eccentricity or torque.
Both are commonly used but there are some major differences between them and where they should be specified. This test method covers the determination of the average residual strength ARS of a fiber-reinforced concrete test beam supported by a steel plate underneath the entire length. The flexural beam is initially cracked from an applied load up to a deflection of 0. The steel plate is then removed and the post-crack deflections and loads are measured and recorded during the test up to a final deflection of 0. The ARS is computed using loads at specified beam deflections that are obtained during the test.
