ASTM C Flexural Bend Glass Fiber Reinforced Concrete Test Equipment
Standards Subsctiption may be the perfect solution. Please first log in with a verified email before subscribing to alerts. The values of flexural properties obtained using ASTM C are useful in quality control, ascertaining compliance, research and development, and product design.
ANY concrete made with a 0. Print 1 2 3 4 5 page sstarting from page current page. This standard is also available to be included in Standards Subscriptions. One bucket of each mix made two sets of samples:. The ASTM C test requires the use of a deflection measuring device and a chart recorder to produce a force-deflection chart. 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. 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 samples, analyze the collected data, and finally, interpret those data in order to draw meaningful and helpful conclusions relevant to the concrete countertop industry.
Remember me for one month.
ASTM C947 Flexural Bend Glass Fiber Reinforced Concrete Test Equipment
Have a question about conducting the test for this standard? The goal of the test was to determine whether dry polymers achieve similar flexural strengths as wet polymers in GFRC.
This detailed article explains the context, test procedure, test results, cost analysis and recommendations. Yield measures the first cracking of the cement paste. ASTM grants you a license as follows: This testing c47 is designed to measure and calculate three characteristic properties of the GFRC:.

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.
That Control Sample does not eliminate all other variables besides the polymer. You currently cannot view this content. Content only available by subscription. Search book title Enter keywords for book title search. While choosing only to measure the Flexural Ultimate Strength of GFRC does provide a limited view of the full properties of GFRC, axtm indicates the absolute strength of the material, something every concrete countertop maker wants to know.
We are confident that we have what you are looking for. This standard is not included in cc947 packages. 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. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

Understanding GFRC Tests
We have no document history for this standard. No further reproductions authorized. The machine itself was also valid for the purpose of testing Flexural Ultimate Strength. If you like to setup a quick demo, let us know at support madcad. We have no amendments or corrections for this standard. By means of our concrete testing expertise and modular product design, we will help find the testing solution that is right for you.
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.
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.
In this case, the variable being tested was the polymer. Proceed to Checkout Continue Shopping. Please login to your authorized staff account to use this feature. As the voice of the U.
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. Enter your personal account email address to request a password reset: When designing a testing program, first one must v947 what exactly is being tested, and eliminate other variables that could confound the test results.
Additionally, measuring only the Flexural Ultimate Strength simplified the construction of the machine, as Modulus of Elasticity measurements require a much more expensive machine.
