Print 1 2 3 4 5 page sstarting from page current page. The Flexural Yield Strength also called limit of proportionality. That Control Sample does not eliminate all other variables besides the polymer. Subscription pricing is determined by: Please first verify your email before subscribing to alerts.

There were no books found for the applied search filters. 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. This standard is also available to be included in Standards Subscriptions. Search book title Enter keywords for book title search. This testing procedure is designed to measure and calculate three characteristic properties of the GFRC:.

If the tests to determine whether wet polymers work had used a Control Sample with a 0. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

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. You may delete a document from your Alert Profile at any time.

ASTM C947 Flexural Bend Glass Fiber Reinforced Concrete Test Equipment

No further reproductions authorized. Additionally, measuring only the Flexural Ultimate Strength simplified the construction of the machine, as Modulus of Elasticity measurements require a much more expensive machine.

The values of flexural properties obtained using ASTM C are useful in quality control, ascertaining compliance, research and development, and sstm design.

We are confident that we have what you are looking for. As the voice of the U. ASTM C determines the flexural ultimate strength in bending and the yield strength of glass-fiber reinforced concrete sections by the use of a simple beam of 1. Your Alert Profile lists the documents that will be monitored. The machine itself was also valid for the purpose of testing Flexural Ultimate Strength.

ASTM C Flexural Bend Glass Fiber Reinforced Concrete Test Equipment

All of the samples were tested on the same day: This standard is not included in any packages. Content only available by subscription. Add to Alert PDF. One bucket of each mix made two sets of samples:. In order to assess the effectiveness of the polymers, it was necessary to first build, test and calibrate an in-house test machine, cast and test many, many c9477, analyze the collected data, and finally, interpret those data in order to draw meaningful and helpful conclusions relevant to the concrete countertop industry.

If the document is revised or amended, you will be notified by astmm.

It is well known from decades of research that the addition of wet polymers to GFRC function to eliminate the c97 for a 7-day wet cure. This is a variable that must be eliminated in any test that is trying to measure other factors such as the effectiveness of wet polymer.

The electronic file may not be reproduced in any way. Enter your personal account email address to request a password reset: Modulus of Elasticity is a property well known to engineers and is crucial in structural calculations.

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

If you like to setup a quick demo, let us know at support madcad. You currently cannot view this content. Remember me for one month. No items in cart. 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.

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.

ANY concrete made with a 0. In addition the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise.

In this case, the variable being tested was the polymer. 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.
