ASTM C13 Committee on Concrete Pipe is set to publish C1894 Standard Guide for Microbially Induced Corrosion of Concrete Products, and finalize two proposed documents it references: WK69718 Standard Test Methods for the Determination of the Effects of Biogenic Acidification on Concrete Antimicrobial Additives and/or Concrete Products and WK69719 Standard Test Methods for the Chemical Resistance of Concrete Products to Acid Attack.
The guide and standards will suit concrete producers, admixture companies, agencies and specifiers. Members of Subcommittee C13.03 on Determining the Effects of Biogenic Sulfuric Acid on Concrete Pipe and Structures will report on C1894 and WK69718-19 progress at the next C13 meeting, September 13-16, 2020 in Norfolk, Va. C1894 is available from the ASTM International bookstore.
