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.
Universal, open structure flexural frame, kN cap. Description Literature Contact Us 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. Link to Active This link will always route to the current Active version of the standard. Contact Us View Accessories Catalog. Give one of our cc1609 engineers a call today for help with creating the best budget and testing plan according to ASTM C Work Item s – proposed revisions of this standard.
Supporting rollers are able to rotate on their axes and are not placed in grooves or have other restraints that prevent their free rotation.
Secrets of Reliable Testing. For this reason, the test extends well past the initial peak. Work Item s – proposed revisions of this standard. These tests are significantly affected by the actual frame stiffness therefore the relevant international 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.
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. 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.
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.
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. How can we help you? This test method may be used for comparison of mixtures, quality control, and research and development. They may also be used to monitor concrete quality, to verify compliance with zstm specifications, obtain flexural strength data on fiber-reinforced concrete members subject to pure bending, or to evaluate the quality of concrete in c109.
Software for Series Systems. Concrete – Control consoles for advanced testing: WaveMatrix 2 for Dynamic C16099. Note 1 Residual strength is not a true stress but an engineering stress computed using ast engineering bending theory for linear elastic materials and gross uncracked section properties.
A standard third point flex fixture W was supplied along with custom sensors and mounting jigs to measure the average deflection. Combining values from the two systems may result in non-conformance with the standard. Concrete – Flexural testing frames: Email addresses can only contain letters, numbers and the following special characters: 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.
A specimen size different from the two preferred specimen sizes is permissible. Referenced Documents purchase c16009 The documents listed below are referenced within the subject standard but are not provided as part of the standard. E Deflectometer Deflection Gauge.

Bluehill LE for Basic Testing. The system in fact offers step-by-step flexibility to build your testing system to cover possible future testing needs.
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.
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.
High stiffness flexural frame, kN cap. Note c160 — 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. The flexural tests in asttm with ASTM C are critical to ensure the concrete has the strength needed to properly support the shaft.

Next Checking to see if you are a returning visitor…. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
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 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. Glossary of Materials Testing Terms. Parallel mode is meant to be used for displacement controlled testing on advanced construction materials, e.
