AASHTO TP 119-21 PDF Download

The AASHTO TP 119-21 standard is titled "Standard Method of Test for Electrical Resistivity of a Concrete Cylinder Tested in a Uniaxial Resistance Test". This standard provides a method for determining the electrical resistivity of concrete. The electrical resistivity is an important property to measure as it gives an indication of the concrete's resistance to ionic transport, such as the penetration of chloride ions.

The purpose of this test method is to provide a rapid assessment of the concrete's durability performance. It is applicable to different types of concrete where correlations have been established between the test procedure and long-term durability performance.

By measuring the electrical resistivity of a concrete cylinder using a uniaxial resistance test, this standard allows for a quick evaluation of the concrete's ability to resist the transport of ions. This information can be valuable in assessing the potential for long-term durability of the concrete in various conditions.
