When designing a testing program, first one must determine what exactly is being tested, and eliminate other variables that could confound the test results.

ASTM C Flexural Bend Glass Fiber Reinforced Concrete Test Equipment

This standard is not included in any packages. It allowed CCI to rapidly and inexpensively test a broad range of mix designs and ingredients with the full confidence that the results are real, valid and comparable to those obtained from an independent testing laboratory using far more expensive machinery.

Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM C The goal of the test was to determine whether dry polymers achieve similar flexural strengths as wet polymers in GFRC. No further reproductions authorized. 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.

Please first verify your email before subscribing to alerts. You may delete a document from your Alert Profile at any time. It is well known from decades of research that the addition of wet polymers to GFRC function to eliminate the need for a 7-day wet cure.

The right to access the electronic files of ASTM Standards is for purposes of viewing for individual use only. If the tests to determine whether wet polymers work had used a Control Sample with a 0. The electronic file may not be reproduced in any way.

The machine itself was also valid for the purpose of testing Flexural Ultimate Strength.

Register for a trial account. A Control Sample or Control Group must be designed to eliminate these other, non-relevant variables.

Modulus of Elasticity is a property well known to engineers and is crucial in structural calculations. ANY concrete made with a 0.

Understanding GFRC Tests

If the document is revised or amended, you will be notified by email. Additionally, measuring only the Flexural Ultimate Strength simplified the construction of the machine, as Modulus of Elasticity measurements require a much more expensive machine.

ASTM grants you a license as follows: There were no books found for the applied search filters. The values of flexural properties obtained using ASTM C are useful in quality asym, ascertaining compliance, research and development, and product design. This detailed article explains the context, test procedure, test results, cost analysis and recommendations. Already Subscribed to this document. As stated in our report, multiple identical samples were tested at Applied Materials and Engineering in Oakland California, the same facility that has conducted manufacturer-sponsored testing for at least one of the dry polymers we tested.

This test method covers determination of the modulus of rupture in bending and the flexural proportional elastic limit of glass-fiber reinforced concrete sections by the use of a simple beam of 1. Need more than one copy?

While choosing only to measure the Flexural Ultimate Strength of GFRC does provide a limited view of the full properties of GFRC, it indicates the absolute strength of the material, something every concrete countertop 9c47 wants ast know.

No items in cart. Yield measures the first cracking of the cement paste. One bucket of each mix made two sets of samples:. We are confident that we have what you are looking for. The ASTM C test asttm the use of a deflection measuring device and a chart recorder to produce a force-deflection chart. However, neither the deflection recording device nor the chart recorder is needed to measure or calculate the Flexural Ultimate Strengthwhich is the absolute strength of the material before it fails.

This testing procedure is designed to measure and calculate three characteristic properties of the GFRC:. You currently aatm view this content.
