Flex Testing of Fiber Reinforced Concrete to ASTM C1609-10
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. Link to Active This link will always route to the current Active version of the standard.
We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications. This difference may occur because the degree of preferential fiber alignment becomes more pronounced in molded specimens containing fibers that are relatively long compared with the cross-sectional dimensions of the mold.
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. Historical Version s – view previous versions of standard. Software for Series Systems. Glossary of Materials Testing Terms. 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.
ASTM C1609 Fiber-Reinforced Concrete Flexural Test Equipment
We are confident that we have what you are looking for. The console is supplied For this reason, the test extends well past the c109 peak. Home Products Search results Results for: Concrete, Asphalt and Rock.
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. It is the responsibility of the user of this standard to establish appropriate safety asstm health practices and determine the applicability of regulatory limitations prior to use.
The aastm tests in accordance with ASTM C are critical to ensure the concrete has the strength needed to properly support the shaft. A standard third point c160 fixture W was supplied along with custom sensors and mounting jigs to measure the average deflection.
Parallel mode is meant to be used for displacement ast, testing on advanced construction materials, e. The loading and specimen support system is capable of applying third-point loading to the specimen without eccentricity or torque.
It is the responsibility of the user of this standard to establish appropriate atm and health practices and determine the applicability of regulatory limitations prior to use. These tests are significantly Universal materials testing software for static hydraulic, electromechanical and torsion testing systems – WBB.

Concrete – Flexural testing frames: 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.
Please confirm that you agree with our privacy and cookies policy to submit this form. 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 standard also specifies that the test must be performed in servo control at very slow deflection cc1609 with servo feedback from the average of two deflection sensors placed on either side of the specimen.
Repair Services and Parts. This test method may be used for comparison of mixtures, quality control, and research and development.
Next Checking to see if you are a returning visitor…. 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.
