ASTM C1894-19 PDF Download

ASTM C1894-19 is a standard guide that focuses on microbially induced corrosion (MIC) of concrete products and provides laboratory test methods for assessing the resistance of concrete to MIC. The guide covers not only concrete products but also cementitious mortar and paste used in specialized applications or laboratory investigations.

It is important to note that while the guide discusses concrete materials and admixtures, it does not specifically address field exposure conditions or the design of sewage pipes, concrete tanks, or concrete riser networks. Additionally, it does not cover live trial tests where concrete specimens are monitored in sewers.

Furthermore, the standard does not cover concrete deterioration caused by chemical sulfate attack, which is a reaction between sulfate compounds in wastewater and cement hydration products. Test methods for assessing sulfate attack are provided by other standards such as Test Methods C452 and C1012/C1012M.

The guide includes explanatory notes and footnotes, which provide additional information. However, it is important to note that these notes and footnotes (excluding those in tables and figures) are not considered requirements of the standard.
