Work Item
ASTM WK91969
Revision of C156-20 Standard Test Method for Water Loss [from a Mortar Specimen] Through Liquid Membrane-Forming Curing Compounds for Concrete
Rationale
ASTM C156 requires the use of portland cement conforming to the requirements for Type I of Specification C150. Many cement producers have stopped producing C150, Type I cement. Therefore, many laboratories can no longer get C150, Type I cement. C156 is adding a language to allow the use of portland-limestone cement conforming to the requirements for Type IL of Specification C595.
