AASHTO T119 Compressive Strength of CylindersAASHTO T119 Compressive Strength of Cylinders Laboratory Testing Service
The AASHTO T119 standard is a widely accepted testing method for evaluating the compressive strength of cylindrical specimens, commonly used in the construction industry. The standard is published by the American Association of State Highway and Transportation Officials (AASHTO) and provides guidelines for conducting laboratory tests to determine the compressive strength of concrete cylinders.
International and National Standards
The AASHTO T119 standard is based on international standards such as ISO 1920-1:2013, which specifies the requirements for testing the compressive strength of concrete. The European Standard EN 12390-3:2009 also provides guidelines for testing the compressive strength of concrete cylinders.
Standard Development Organizations
The development and maintenance of AASHTO standards are overseen by the AASHTO Committee on Materials (MMS) and the AASHTO Technical Committee on Materials. These committees consist of experts from various industries, including construction, materials science, and engineering.
Evolution of Standards
Standards evolve over time to reflect changes in technology, regulations, and industry practices. The AASHTO T119 standard has undergone revisions to incorporate new testing methods and procedures. For example, the 2017 edition of the standard introduced new provisions for testing concrete cylinders with different shapes and sizes.
Standard Numbers and Scope
The AASHTO T119 standard is designated as AASHTO T119-17 (2017). The scope of the standard includes:
