Smart EPD lists the new rule as Part B PCR for Cementitious Materials, Standard 1000-017, version 1.0, published September 4, 2026, and valid through September 4, 2031. The change is intended to align reporting rules and improve coverage of blended cements; it does not, by itself, demonstrate emissions reductions.
What changed in the cementitious materials PCR?
The American Cement Association (ACA), Slag Cement Association, Natural Pozzolan Association and American Coal Ash Association collaborated on a consolidated rule. ACA’s October 5, 2026 announcement describes it as bringing together three prior PCRs: rules for cement, slag cement, and SCMs, including coal ash and natural pozzolans. A PCR sets product-category requirements used to prepare an environmental product declaration (EPD).
The current Smart EPD listing identifies the consolidated rule as Smart EPD Part B PCR for Cementitious Materials, Standard 1000-017, version 1.0. The listing names ISO 14025:2006 and ISO 21930:2017 as its conformance basis. It marks the earlier Part B PCR for Cements for Construction 1000-010 v4.0 and Part B PCR for Supplementary Cementitious Materials 1000-002 v1.0 as superseded.
Why unify rules for cement and SCMs?
SCMs such as slag cement, coal ash and natural pozzolans can be incorporated into blended cements. ACA says the consolidated PCR is intended to align the rules for SCMs more closely with those for cement and improve reporting for blended cement products. The association presents reduced duplication and more uniform rule application as goals, not as measured outcomes.

For producers preparing declarations, a shared framework can help establish consistent category rules across materials. For owners, designers, specifiers, ready-mix concrete producers and precast manufacturers, EPDs provide information used in material selection, procurement and environmental-performance accounting, according to ACA. A common PCR does not make every EPD directly comparable: product category, geography, declared scope and data still matter.
What updated EPDs has ACA announced?
ACA says its EPD consultant has started surveying U.S. cement manufacturers to collect data for updated industry-average EPDs. The planned national coverage comprises four categories:
Rank #2
- 72hr Lab Fee Included - No further costs to process your sample
- PLM Testing Method - Your results will tell you which kind of asbestos was detected along with a percentage concentration
- 3 Day Results (All samples are tested within 72hrs of receipt)
- Perfect for testing Popcorn Ceilings, Cement, Siding, Guttering, Boarding & Floor Tiles
- Portland cement, associated with ASTM C150/AASHTO M 85.
- Portland-limestone cement, associated with ASTM C595/M 240.
- Blended cements, associated with ASTM C595/M 240.
- Masonry cement, associated with ASTM C91.
ACA says it also plans regional EPDs for these categories where possible. The survey and planned coverage are steps toward updated declarations; the announcement does not state that the new EPDs have been published.
ACA’s Quantifying Environmental Impact background page describes earlier industry-average cement EPDs and the transition through prior PCR versions. For the rule’s current status, the Smart EPD library is the relevant reference because it now labels the earlier cement and SCM rules as superseded.

What the dates and statistics do—and do not—show
| Figure | What it describes |
|---|---|
| Three prior PCRs | Rules for cement, slag cement and SCMs consolidated into one, according to ACA’s October 5, 2026 announcement. |
| Four EPD categories | National industry-average cement EPD categories ACA says it plans to update: portland, portland-limestone, blended and masonry cement. |
| September 4, 2026–September 4, 2031 | Publication date and stated validity period for Smart EPD PCR 1000-017 v1.0. |
These are scope and administrative facts. ACA’s announcement does not report a quantified emissions reduction, cost saving, adoption rate or measured improvement in reporting. The new rule establishes a framework for preparing EPDs; it is not evidence that cement or concrete emissions have already fallen.

When using an EPD to compare cementitious materials or support procurement decisions, check the declaration itself rather than assuming a shared PCR makes two products interchangeable. Relevant details include:
Rank #4
- Accurate Concrete Workability Testing: Designed for measuring the consistency and workability of fresh concrete during mixing and pouring applications in construction and lab environments.
- Durable Galvanized Steel Construction: Made from galvanized steel for reliable performance in demanding job site and testing conditions. The smooth inner surface of the slump cone reduces concrete adhesion, making it easy to clean.
- Easy Operation: A convenient handle is integrated on the side of the slump cone, which is the core design to improve operational convenience. The handle is ergonomically designed to achieve smooth vertical lifting, easy to operate.
- Complete All-In-One Kit – The set includes all essential components for slump testing: a standard slump cone (12"/300 mm height, 8"/200 mm bottom diameter, 4"/100 mm top diameter), a non-absorbent base plate, a 24" steel tamping rod (5/8" diameter), a concrete shovel, a filling funnel, and a steel ruller.
- Versatile Application Scenarios: Suitable for testing fresh concrete workability in various scenarios, including construction sites, road and pavement projects, building foundations, and material testing lab, ideal for concrete contractors, engineers, and construction professionals.
- Product category and cement type: Confirm that the declarations cover the products being compared.
- Geography: Check whether an industry-average or regional declaration represents the relevant supply area.
- PCR and version: Note the rules named in the EPD and whether they are the current applicable version.
- Scope and data: Review declared system boundaries and data quality before interpreting environmental indicators.
- Declaration type: Distinguish a product-specific EPD from an industry-average EPD.
ACA also describes the GCCA EPD Tool as software for creating draft EPDs for clinker, cement, aggregate, concrete and precast products. Its background page says the tool includes North American and international modules because regional rules differ. Producers considering the tool should check ACA’s page for current access terms and availability.
Quick Recap
Best Value
- High Precision: The bulk density tester for powder provides accurate measurement results. There is a level at the bottom to adjust the level. Attention: Data measurement needs to be conducted in a balanced state
- Measurement Principle: Let the powder fall from a funnel(taper 60°±0.5°,Volume 120ml) at a certain height until the measuring cup(100ml) is filled, and weigh a specific volume of bulk powder, which is the bulk density
- High Quality Stainless Steel: The natural accumulation density tester uses thickened stainless steel material for the volumetric meter, with sufficient wall thickness and hardness, durability, and wear resistance. The measuring frame is made of stainless steel to prevent dust from falling during loading
- Stable Base: The powder stacking density tester adopts a fixed stainless steel base, and the base has triangular adjustable screws that can adjust the height according to needs
- Widely Used: Bulk density meter can measure the density of various powders. For example: metal powder, rare metal powder, alloy powder, soil, dye, abrasive, paint, cement, water sediment powder, etc
