The quintessential standard for evaluating corrosion-inhibiting admixtures and their effects on a cement mix is ASTM C1582. This standard relies on ASTM G109 and ASTM G180 to determine the admixture's impact on corrosion rate in concrete. Unfortunately these tests come with several intrinsic issues that limit their use and consistency. Importantly ASTM G109 runs for several years and ASTM G180 has an experimental precision of one magnitude. At this time ASTM G180 remains the most favorable test to perform regardless of its innacuracy because it only requires roughly three days of experimentation.This report will evaluate an ASTM G31 (Standard Guide for Laboratory Immersion Corrosion Testing of Metals) test run in similar conditions to ASTM G180. Immersion testing typically yields precise results and since ASTM G180 is already an immersion test evaluated by electrochemical methods a similar ASTM G31 test has the potential to afford comparable results that are easier to understand and utilize while still maintaining higher precision.
