Portland-Limestone Cement

Portland-limestone cement (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. Sustainability encompasses many aspects designed to improve construction practices, including: more efficient ...
