# ASTM C947

Standard Test Method for Flexural Properties of Thin-Section Glass-Fiber-Reinforced Concrete (Using Simple Beam With Third-Point Loading)

[Back to all techniques](/analytical-techniques/)

## Significance and Use

3.1 Flexural properties determined by this test method are useful for quality control of glass-fiber reinforced concrete products, ascertaining compliance with the governing specifications, research and development, and generating data for use in product design.

## Scope

1.1 This test method covers determination of the flexural ultimate strength in bending and the yield strength of glass-fiber reinforced concrete sections by the use of a simple beam of 1.0 in. (25.4 mm) or less in depth using third-point loading.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
