ASTM Releases New Product Category Rules for Cements
ASTM International has released the final product category rules (PCR) for portland, blended hydraulic, masonry, mortar and plastic stucco cements.
Development of PCR for the cement industry elevates the visibility and adoption of cement’s sustainable benefits. Product category rules are the basis for environmental product declarations (EPDs), which provide quantified environmental data using predetermined parameters. Ultimately, EPDs allow purchasers and users to make informed comparisons between building materials when using life cycle analysis on construction projects. EPDs rely upon the detailed instructions for data collection and life cycle assessment calculations found within the PCR.
