ASTM RR:G01-1021 PDF Download

The ASTM RR:G01-1021 standard details the procedure for evaluating the effectiveness of corrosion inhibiting admixtures in protecting steel in concrete. The test method involves measuring the polarization resistance of steel electrodes embedded in cementitious slurries containing the admixture.

The standard outlines the equipment, specimen preparation, and testing procedure required for conducting the polarization resistance measurements. It provides guidelines for the selection and preparation of the cementitious slurries, as well as the installation and connection of the steel electrodes.

Furthermore, the standard describes the electrical circuit setup and the specific conditions under which the polarization resistance measurements should be performed. These measurements are crucial for determining the corrosion rate and effectiveness of the corrosion inhibiting admixture in preventing steel corrosion in concrete.
