They may also be used to monitor concrete quality, to verify compliance with construction specifications, obtain flexural strength data on aastm concrete members subject to pure bending, or to evaluate the quality of concrete in service. The appropriateness of each parameter depends on the nature of the proposed application and the level of acceptable cracking and deflection serviceability.

ASTM C Fiber-Reinforced Concrete Flexural Test Equipment

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. We are confident that we have what you are looking for. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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.

Work Item s – proposed revisions of this standard. A standard third point flex fixture W was supplied along with custom sensors and mounting jigs to measure the average deflection. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. 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.


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.

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. E Deflectometer Deflection Gauge.

Ast, of Aztm Testing Terms. The standard also specifies that the test must be performed in servo control at very slow deflection rates with servo feedback from the average of two deflection sensors placed on either side of the specimen.

Work Item s – proposed revisions of this standard. 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.

Supporting rollers are able to rotate on their axes and are not placed in grooves or have other restraints that prevent their free rotation. WaveMatrix 2 for Dynamic Testing. Note 5 — 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.

Email addresses can only contain letters, numbers and the following special characters: How can we help you? 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 flexural tests in accordance with ASTM C are critical to ensure the concrete has the strength needed to properly support the shaft. Fiber-reinforced concrete is influenced in different ways by the amount and type of fibers in the concrete.

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.

This test method may be used for comparison of mixtures, quality control, and research and development. Iva Company info Privacy policy For this reason, the test extends well past the initial peak. Software for Series Systems. Link to Active This link will always route to the current Active version of the standard. By means of our bend testing expertise and modular product design, we will help find the testing solution that is right for you.


Parallel mode is meant to be used for displacement controlled testing on advanced construction materials, e.

Have a question about conducting the test for this standard? The console is supplied 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.

Secrets of Reliable Testing. Historical Version s – view previous versions of standard. 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.

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. Give one of our application engineers a call today for help with asstm the best budget and testing plan according to ASTM C The system in fact offers step-by-step flexibility asgm build your testing system to cover possible future testing needs.

Home Products Search results Results for: Concrete – Flexural testing frames: 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. 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.

Universal, open structure flexural frame, kN cap.
