Need more than one copy? The values of flexural properties obtained using ASTM C are useful in quality control, ascertaining compliance, research and development, and product design. 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.
This standard is also available to be included in Standards Subscriptions. Subscription pricing is determined by: Already Subscribed to this document. All of the samples were tested on the same day: The machine itself was also valid for the purpose of testing Flexural Ultimate Strength. The Flexural Yield Strength also called limit of proportionality. As the voice of the U. 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.

No further reproductions authorized. This is a variable ast, must be eliminated in any test that is trying to measure other factors such as the effectiveness of wet polymer. The electronic file may not be reproduced in any way. That Control Sample does not eliminate all other variables besides the polymer. The goal of the test was to determine whether dry polymers achieve similar flexural strengths as wet polymers in GFRC.

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. 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.

Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM C This testing procedure is designed to measure and calculate three characteristic properties of the GFRC:. 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.
