ASTM launches standard to cover effects of MIC on concrete products

ASTM International has released a standard to help guide standards related to determining the effects of biogenic sulfuric acid on concrete products.

ASTM member Mel Marshall says the standard serves as a guide that discusses microbially induced corrosion (MIC) of concrete products and laboratory test methods for determining the resistance of concrete to MIC.

Marshall- president of Mel C. Marshall Industrial Consultants – confirmed the subcommittee responsible for the standard is developing two additional standards for test methods referenced in this new standard. These proposed standards cover the determination of effects of biogenic acidification on concrete antimicrobial additives and/or concrete products (WK69718) and chemical resistance of concrete products to acid attack (WK69719).

ASTM says the standard will mainly be used by agencies, specifiers, admix suppliers and concrete manufacturers. It was approved by ASTM’s concrete pipe committee and will soon be published as C1894.
