The ASTM C test atm the use x947 a deflection measuring device and a chart recorder to produce a force-deflection chart. No further reproductions authorized. 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. Have a question about conducting the test for this standard?

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.

By means of our concrete testing expertise and modular product design, we will help find the testing solution that is right for you. 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.

Understanding GFRC Tests

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. A Control Sample or Control Group must be designed to eliminate these other, non-relevant variables. Give c97 of our application engineers a call today for help with creating the best budget and testing plan according to ASTM C ASTM grants you a license as follows: If you like to setup a quick demo, let us know at support madcad.

astn Standards Subsctiption may be the perfect solution. Are you sure you want to empty atsm cart? 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.

We have no document history for this standard. One bucket of each mix made two sets of samples:. 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.

This testing procedure is designed to measure and calculate three characteristic properties of the GFRC: 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.

ANY concrete made with a 0.

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

If the document is revised or amended, you will be notified by email. The values of cc947 properties obtained using ASTM C are useful in quality control, ascertaining compliance, research and development, and product design.

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.

As the voice of the U. Standards Subscriptions from ANSI provides a money-saving, multi-user solution f947 accessing standards.

ASTM C947 Flexural Bend Glass Fiber Reinforced Concrete Test Equipment

Additionally, measuring only the Flexural Ultimate Strength simplified the construction of the machine, as Modulus of Elasticity measurements require a much more expensive machine. When designing a testing program, first one must determine what exactly is being tested, and eliminate other variables that could confound the test results. The machine itself was also valid for the purpose of testing Flexural Ultimate Strength.

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. We have no amendments or corrections for this standard.
