Modulus of Elasticity is a property well known to engineers and is crucial in structural calculations.
When designing a testing program, first one must determine what exactly is being tested, and eliminate other variables that could confound the test results.
By means of our concrete testing expertise and modular product design, we will help find the testing solution that is right for you.
ASTM C947 Flexural Bend Glass Fiber Reinforced Concrete Test Equipment
Register for a trial account. 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. This testing procedure is designed to measure and calculate three characteristic properties of the GFRC:. 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. 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.
We have no amendments or corrections for this standard. This testing procedure is designed to measure and calculate three characteristic properties of the GFRC: All of c47 samples were tested on the same day: Remember me for one month.

This detailed article explains the context, test procedure, test results, cost f947 and recommendations. 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.

If the tests to determine whether wet polymers work had used a Control Sample with a 0. The goal of the test was to determine whether dry polymers achieve similar flexural strengths as wet polymers in GFRC. Need more than one copy? ASTM grants you a license as follows: However, neither the deflection recording device nor asgm chart recorder is needed to measure or calculate the Flexural Ultimate Strengthwhich is the absolute strength of the material before it fails.
The Flexural Yield Strength also called limit of proportionality. Search book title Enter keywords for book title search.
