Figure 12. Results of “cube” tests for the frost resistance of concrete. Mass loss of less than 10% is considered acceptable. Here the portland limestone cements, PKZ 35 F (with limestone contents of 13% to 17%), performed better than the companion portland cements, PZ 35 F (adapted from Schmidt et al. 1993).-"THE USE OF LIMESTONE IN

Quality control of the limestone, limestone portland cement, and concrete is also discussed. In general, the addition of up to 5% limestone does not affect the performance of portland cement. Strengths of cements with limestone can be optimized by grinding to an appropriate particle size distribution.

Portland-limestone cement (PLC), or Type IL cement, is a cement formulation based on portland cement clinker, with additional limestone used as an ingredient, in amounts up to 15% by mass. The environmental benefits of cements with limestone are appreciable: because less limestone is

PLC is typically slightly lighter in color than OPC due to the lighter color of limestone (see Figure C, below). PLC is ground finer. The Blaine is about 5000-5500, as opposed to OPC at about 4000 (cm 2 /g). The higher Blaine is mainly due to the soft limestone grounding very fine. Ready-mix producers who have transitioned to PLC report that

· As the Portland Cement Association (PCA) notes, “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.”. In short, PLC speeds the transition to
