This webinar will focus on the future of Portland Limestone Cement in California as a sustainable choice for construction.

Portland cement manufacturers have developed a modified cement formulation called Portland Limestone Cement, or PLC to respond to growing calls for reducing embodied carbon associated with construction. PLC is a blended cement with a higher limestone content, which results in a product that works the same, measures the same, and performs the same, but with a reduction in carbon footprint of 10% on average.

Come hear from Nathan Forrest, PETechnical Director of the California Nevada Cement Association (CNCA) who will explain the research that has been done in this area, the history of adoption going back several decades, and the pending adoption at the state level in California.
