ASTM International Releases New Product Category Rules for Several Cements

Words: Dan Kamys



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.

“I commend our member cement companies for collaborating on a standardized method for discussing
information about the environmental impact of several cement products,” says Cary Cohrs, PCA Board
of Directors chairman. “Through this process, we are able to truly understand the impact of cement
on the environment.”

According to ASTM, “In order to create a comparable EPD, they must follow the same rules,” said
Christopher Surak, director of certification programs at ASTM International. “PCRs, similar to standards,
are developed in a collaborative manner and ASTM is uniquely positioned to provide the venue for
developing an industry PCR.”

The real cost of equipment ownership isn't what you pay on day one. It's what happens over the years that follow. The purchase price of a new mortar mixer, grout pump, material handling system, or masonry saw is only part of the investment. What happens

Installation Starts Before the First Course

Some of the most expensive masonry installation problems begin long before crews arrive onsite. By the time a project reaches the field, many coordination decisions have already been made. Dimensional conflicts, congested reinforcement, specialty materia

Designing for Performance: Key Considerations for Efficient, Durable Masonry Projects

A successful masonry project starts well before the first stone is set. The craftsmanship on site matters, of course, but many of the decisions that shape the final result are made much earlier—during design, detailing, and material selection. Those choic
