ASTM C1894-22 PDF Download

ASTM C1894-22 is a standard guide that discusses microbially induced corrosion (MIC) of concrete products. The purpose of this guide is to provide information on laboratory test methods for determining the resistance of concrete to MIC. While the guide primarily focuses on concrete products, it also covers cementitious mortar and paste used in specialized applications or laboratory investigations.

It's important to note that this standard does not specifically address field exposure conditions or the design of sewage pipes, concrete tanks, or concrete riser networks. It also doesn't cover live trial tests where concrete specimens are monitored in sewers. Additionally, the standard excludes the topic of concrete deterioration due to chemical sulfate attack, as this is caused by a reaction between sulfate compounds in wastewater and cement hydration products. Test methods for assessing sulfate attack are covered in other ASTM standards.

The guide contains explanatory notes and footnotes, but it clarifies that these should not be considered as requirements of the standard, unless specified otherwise.
