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. 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.
One bucket of each mix made two sets of samples:. If the tests to determine whether wet polymers work had used a Control Sample with a 0. The goal of the test was to c9947 whether dry polymers achieve similar flexural strengths as wet polymers in GFRC. We are confident that we have what you are looking for. No items in cart.

Please first verify your email before subscribing to alerts. Yield measures the first cracking of the cement paste. In addition the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise. 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.
Print 1 2 3 4 5 page sstarting from page current page. There were no books found for the applied search filters. 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.
This standard is not included in any packages. Add to Alert PDF.

The values of flexural properties obtained using ASTM C are useful in quality control, ascertaining compliance, research and development, and product design.
A Control Sample or Control Group must be designed to eliminate these other, non-relevant variables. If the document is revised or amended, you will be notified by email.
Already Subscribed to this document. We have no document history for this standard. This standard is also available to be included in Standards Subscriptions. In this case, the variable being tested was the polymer. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. 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.
We have no amendments or corrections for this standard. The Flexural Yield Strength also called limit of proportionality.
ASTM C Flexural Bend Glass Fiber Reinforced Concrete Test Equipment
When designing a testing program, first one must determine what exactly is being tested, and eliminate other variables that could confound the test results. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
Standards Subsctiption may be the perfect solution. This testing procedure is designed to measure and calculate three characteristic properties of the GFRC:. 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.
No further reproductions authorized. Modulus of Elasticity is a property well known to engineers and is crucial in structural calculations.
ASTM C947 Flexural Bend Glass Fiber Reinforced Concrete Test Equipment
Enter your personal account email address to request a password reset: The ASTM C test requires the use of a deflection measuring device and a chart recorder to produce a force-deflection chart. You may delete a document from your Alert Profile at any time. ASTM grants you a license as follows: Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension c97 compression tests These dual column testers are available in both tabletop and floor standing models.

Please login to your authorized staff account to use this feature. Additionally, measuring only the Flexural Ultimate Strength simplified the construction of the machine, as Modulus of Elasticity measurements require a much more expensive machine. 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.
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.
