Have a question about conducting the test for this standard? Note 5 — The results obtained using one size molded specimen may not correspond to the performance of larger or cc1609 molded specimens, concrete in large structural units, or specimens sawn from such units. Combining values from the two systems may result in non-conformance with the standard.
These tests are significantly 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Email addresses must contain the symbol. 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. The appropriateness of each parameter depends on the nature of the proposed application and the level of acceptable cracking and deflection serviceability.
Awtm Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. They may also be used to monitor concrete quality, to verify compliance with construction specifications, obtain flexural strength data on fiber-reinforced concrete members subject to pure bending, or to evaluate the quality of concrete in service. WaveMatrix 2 for Dynamic Testing.
Flex Testing of Fiber Reinforced Concrete to ASTM C1609-10
A specimen size different from the two preferred specimen sizes is permissible. E Deflectometer Deflection Gauge. 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 qstm the test specimen and the loading configuration. A standard third point flex fixture W was supplied along with custom sensors and mounting jigs to measure the average deflection.
By means of our bend testing expertise and modular product design, we will help find the testing solution that is right for you.
Universal, open structure flexural frame, kN cap. Home Products Search results Results for: 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.
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. Specimen toughness is a measure of the energy absorption capacity of the test specimen. 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.
Supporting rollers are able to rotate on their axes and are not placed in grooves or have other restraints that prevent their free rotation. Repair Services and Parts.
Secrets of Reliable Testing. At the option of c609 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.

Glossary of Materials Testing Terms. Next Checking to see if you are a returning visitor…. The first-peak strength, peak strength, and residual strengths determined asmt this test method reflect the behavior of fiber-reinforced concrete under static flexural loading. Work Item s – proposed revisions of this standard. The loading and specimen support ast, is capable of applying third-point loading to the specimen without eccentricity or torque.
Fiber-reinforced concrete is influenced in different ways by the amount and type of fibers in the concrete. The console is supplied We are confident that we have what you are looking for. 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 flexural tests in accordance with ASTM C are critical to ensure the concrete has the strength needed to properly support the shaft.
The flexural specimens are created as the concrete is being applied and must be tested within hours of being applied making it impossible to use a test lab.
The initial crack in the asym and the associated jump in deflection servo feedback make servo control very challenging. Combining values from the two systems may result adtm non-conformance with the standard.
