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. Are you sure you want to empty the cart?

It allowed CCI to rapidly and inexpensively test a broad range of mix designs and c9947 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.

ASTM C947 Flexural Bend Glass Fiber Reinforced Concrete Test Equipment

D947 of Elasticity is a property well known to engineers and is crucial in structural calculations. Additionally, measuring only the Flexural Ultimate Strength simplified the construction of the machine, as Modulus of Elasticity measurements require a much more expensive machine.

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. However, neither the deflection recording device nor the chart recorder is needed to measure or calculate c497 Flexural Ultimate Strengthwhich is the absolute strength of the material before it fails. We have no document history for this standard.

The Flexural Yield Strength also called limit of proportionality. The goal of the test was to determine whether dry polymers achieve similar flexural strengths as wet polymers in GFRC.
