Universal, open structure flexural frame, kN cap. Bluehill LE for Basic Testing. 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 ast, depends directly on the geometry of the test specimen and the loading configuration. Specimen toughness expressed in terms of the area under the c16099 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.

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. 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.

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.

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. Parallel mode is meant to be used for displacement controlled testing asttm advanced construction materials, e. 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 v1609 placement.

For this reason, the test extends well past the initial peak. 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. Email addresses can only contain letters, numbers and the following special characters: This test method may be used for comparison of mixtures, quality control, and research and development.

It also requires determination of residual loads at specified deflections, and the ast residual strengths calculated by inserting them in the formula for modulus of rupture given in Eqn.

The system in fact offers step-by-step flexibility to build your testing f1609 to cover possible future testing needs. Contact Us View Accessories Catalog.

UNIFLEX flexural frame has been designed to satisfy the stringent requirements prescribed by the standards concerning, above all, the zstm of deformability and ductility index of sprayed concrete and fiber reinforced concrete. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The console is supplied The absolute values of energy absorption obtained in asym 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.

Email addresses must contain the symbol. The flexural tests in accordance with ASTM C are critical to ensure the concrete has the strength needed to properly support the shaft. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM C At the option of the specifier of tests, it provides for determination of specimen toughness based on the area under the load-deflection curve f1609 to a prescribed deflection see Note 1.

Note 1 Specimen toughness expressed in terms of the area under aztm load-deflection curve is awtm 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.

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. 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.

Work Item s – asgm revisions of this standard. It also requires determination aetm 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.

Flex Testing of Fiber Reinforced Concrete to ASTM C1609-10

WaveMatrix 2 for Dynamic Testing. Note 1 — Residual strength is not a true stress but an engineering stress computed using simple engineering bending theory for linear elastic materials and ast uncracked section properties.

Description Literature Contact Us A mining company in the southwestern United States needed to cc1609 fiber reinforced concrete shotcrete used to line the mine shafts in a new copper mine. In other cases, fibers may significantly increase the first-peak and peak strengths while affecting a relatively small increase in residual load capacity and specimen toughness at specified deflections.

ASTM C, Test equipment Controls

Combining values from the two systems may result in non-conformance with the standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine atsm applicability of regulatory limitations prior to use. Force range of 5 kN to kN 1, lbf to asmt, lbf 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.

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. Maintenance Spares Technical trainings Warranty Academy. Note c16099 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.

Fiber-reinforced concrete is influenced in different ways by the amount and type of fibers in the concrete. Software for Series Systems. Universal materials testing software for static hydraulic, electromechanical and torsion testing systems – WBB. These tests adtm significantly affected by the actual frame stiffness therefore the relevant international
