US: The state governments of Arizona, Maryland and Vermont have approved the use of Portland limestone cement (PLC) in public construction projects. The rule changes bring the total number of states in which PLC may be used in this way to 44.
The Portland Cement Association (PCA) has welcomed the decision. The association said "Widespread acceptance of PLC marks a significant step to reducing the carbon footprint of concrete construction and advancing the goals laid out in the PCA Roadmap to Carbon Neutrality."
