This testing procedure is designed to measure and calculate three characteristic properties of the GFRC:.
ASTM grants you a license as follows: ANY concrete made with a 0. Yield measures the first cracking of the cement paste. Need more than one copy? This standard is also available to be included in Standards Subscriptions. Your Alert Profile lists the documents that will be monitored. The machine itself was also valid for the purpose of testing Flexural Ultimate Strength.
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 the document is revised or amended, you will be notified by email. You may delete a document from your Alert Profile at any time. As the voice of aatm U.
By means of our concrete testing expertise and modular product design, we will help find the testing solution that is right for you.
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.
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. As stated in our report, multiple identical aatm 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. Are you sure you want to empty the cart?
This standard is not included in qstm packages. There were no books found for the applied search filters. ASTM C determines the flexural ultimate strength in bending and the yield strength of glass-fiber reinforced concrete sections by atm use of a simple beam of 1. 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

Already Subscribed to this document. That Control Sample does not eliminate all other variables besides the polymer. Have a question about conducting the test for this standard?
All of the samples were tested on the same day: We have no amendments or corrections for this standard. The goal of the test was to determine whether astn polymers achieve similar flexural strengths as wet polymers in GFRC. 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.
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.

Additionally, measuring only the Flexural Ultimate Strength simplified the construction of the machine, as Modulus of Elasticity measurements require a much more expensive machine.
