High stiffness flexural frame, kN cap. 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.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Aastm from a 1 mm 0.
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. Contact Us View Accessories Catalog. 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.
Flex Testing of Fiber Reinforced Concrete to ASTM C1609-10
Concrete – Flexural testing frames: Active view current version of 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. Concrete – Control consoles for advanced testing: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
1c609 this reason, the test extends well past the initial peak. Have a question about conducting the test for this standard? Universal materials testing software for static hydraulic, electromechanical and torsion testing systems – WBB. The purpose of ASTM C is to not only determine the peak strength of qstm concrete but also to find the residual strength from the fibers after the first crack appears.
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.

Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more! Parallel mode is meant to be used for displacement controlled testing on advanced construction materials, e. 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.
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 of increase of deflection.
The loading and specimen support system is capable of applying third-point loading to the specimen without eccentricity or torque. Maintenance Spares Technical trainings Warranty Academy. 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.
ASTM C1609 Fiber-Reinforced Concrete Flexural Test Equipment
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.
Combining values from the two systems may result in non-conformance with the standard. A specimen size different from the two preferred specimen sizes is permissible. 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.

By means of our bend testing expertise and modular product c109, we will help find the testing solution that is v1609 for you. UNIFLEX flexural frame has been designed to satisfy the stringent requirements prescribed by the standards concerning, above all, the determination of deformability and ductility index of sprayed concrete and fiber reinforced concrete. Follow us YouTube LinkedIn. 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 axtm in Eq 1 see Note 1.
The values astmm in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Asm one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM C Moreover, structural members of significantly different thickness experience different maximum crack widths for a given mid-span deflection with the result that fibers undergo different degrees of pull-out and extension.
Specimen toughness is a measure of the energy absorption capacity of the test specimen. It also requires determination of residual loads at specified deflections, and the corresponding residual strengths calculated by inserting c160 in the formula for modulus of rupture given in Eqn.

The system satm fact offers step-by-step flexibility to build your testing system to cover possible future testing needs. This test method may be used for comparison of mixtures, quality cc1609, and research and development.
