Need more than one copy? Additionally, measuring only the Flexural Ultimate Strength simplified the construction of the machine, as Modulus of Elasticity measurements aastm a much more expensive machine. Are you sure you want to empty the cart? In this case, the variable being tested was the polymer.

Understanding GFRC Tests

When designing a testing program, first one must determine what exactly is being tested, and eliminate other variables that could confound the test results. Please first verify your email before subscribing to alerts. The machine itself was also valid for the purpose of testing Flexural Ultimate Strength.


As the voice of the U. Print 1 2 3 4 5 page sstarting from page current page. 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. That Control Sample does not eliminate all other variables besides the polymer.

By means of our concrete testing expertise and modular product design, we will help find the testing solution that is c9447 for you. Search book title Enter keywords for book title search.

If you like to setup a quick demo, let us know at support madcad. This testing procedure is designed to measure and calculate three characteristic properties of the GFRC:. There were no books found for the applied search filters.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

Your Alert Profile lists the documents that will be monitored. Standards Subsctiption may be the perfect solution. ANY concrete made with a 0. Subscription pricing is determined asm 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.


Remember me for one month.

Understanding GFRC Tests – Concrete Countertop Institute

It allowed Astj to rapidly and inexpensively test a broad range of mix designs and ingredients with the full confidence that the results are atm, valid and comparable to those obtained from an independent testing laboratory using far more expensive machinery.

In addition the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise. Already Subscribed to this document.

Modulus of Elasticity is a property well known to engineers and is crucial in structural calculations.
