ASTM C947 Flexural Bend Glass Fiber Reinforced Concrete Test Equipment
If the tests to determine whether wet polymers work had used a Control Sample with a 0. 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. We have no amendments or corrections for this standard. Modulus of Elasticity is a property well known to engineers and is crucial in structural calculations.
Cc947 further reproductions authorized. 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.
You can download and open cc947 file to your own computer but DRM prevents opening this file on another computer, including a networked server. Additionally, measuring only the Flexural Ultimate Strength simplified the construction of the machine, as Modulus of Elasticity measurements require a much more expensive machine.

This standard is also available to be included in Standards Subscriptions. In this case, the variable being tested was the polymer. The machine itself was also valid for the purpose of testing Flexural Ultimate Strength. Content only available by subscription. Add to Alert PDF. This testing procedure is atsm to measure and calculate three characteristic properties of the GFRC:.

There were no books found for the applied search filters. 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 maker wants to know.
All of the samples were tested on the same day: Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM C Already Subscribed to this document. If you like to setup a quick demo, let us know at support madcad. By means of our concrete testing expertise and modular product design, we will help find the testing solution that is right for you. Yield measures the first cracking of the cement paste.
Understanding GFRC Tests – Concrete Countertop Institute
It is well known astj decades of research that the addition of wet polymers to GFRC function to eliminate the need for a 7-day wet cure.
The ASTM C test requires the use of a deflection measuring device and a chart recorder to produce a force-deflection chart. Register for a trial account. Please login to your authorized staff account to use this feature. Are you sure you want to empty the cart?
Understanding GFRC Tests
We have no document history for this standard. When designing a testing program, first one must determine what exactly is being tested, and eliminate other variables that could confound the test results. Remember me for one month. 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.
This testing procedure is designed to measure and calculate three characteristic properties of the GFRC: You currently cannot view this content. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
A Control Sample or Control Group must be designed to eliminate these other, non-relevant variables. No items in cart. 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.
