ASTM grants you a license as follows: 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.
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. ASTM C determines the flexural x947 strength in bending and the yield strength of glass-fiber reinforced concrete sections by the use of a simple beam of 1.
Understanding GFRC Tests – Concrete Countertop Institute
All of the samples were tested on the same day: The ASTM C test requires the use of a deflection measuring device and a chart recorder to produce a force-deflection chart.

This detailed article explains the context, test procedure, test results, cost analysis and recommendations. Content only ast by subscription. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM C 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 goal of the test was to determine whether dry polymers achieve similar flexural strengths as wet polymers in GFRC. The values of flexural properties obtained using ASTM C are useful in quality control, ascertaining compliance, research and development, and product design.
ANY concrete made with a 0. We have no amendments or corrections for this standard.

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.

Understanding GFRC Tests
If the tests to determine whether wet polymers work had used a Control Sample with a 0. Your Alert Profile lists the documents that will be monitored. Remember me for one month. The Flexural Yield Strength also called asrm of proportionality. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
This standard is also available to be included in Standards Subscriptions. 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.
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.
Ast this case, the variable being tested was the polymer. Proceed to Checkout Continue Shopping. This testing procedure is designed to measure and calculate three characteristic properties of the GFRC:.
