AASHTO T 177-17 (2021) PDF Download

The AASHTO T 177-17 (2021) standard provides guidelines for determining the flexural strength of small-sized concrete specimens. This method specifically utilizes a simple beam with center-point loading for the testing process. It is important to note that this standard is not intended as a substitute for the T 97 method.

The purpose of this standard is to establish a consistent and reliable procedure for assessing the flexural strength of concrete. Flexural strength is a critical property of concrete as it measures its ability to resist bending or cracking when subjected to external forces. By using a simple beam with center-point loading, this method ensures uniform distribution of the loading force, enabling accurate determination of flexural strength.

It is important to adhere to this standard as it ensures standardized testing procedures and facilitates reliable comparison of flexural strength data among different concrete specimens. Following this method allows for the evaluation of concrete’s structural integrity and performance, aiding in determining its suitability for various engineering applications.
