Portland Limestone Cement Type IL

Portland-limestone cement (PLC) Type IL is formulated with a higher limestone content and manufactured with less embodied energy than ordinary portland cement (OPC). Portland-limestone cement (PLC) Type IL is governed by ASTM C595 or AASHTO M 240 Standard Specification for Blended Hydraulic Cements. It is a blended cement manufactured with a limestone content between 5% and 15%. Optimized particle packing and enriched nucleation sites allow PLCs to match the performance of ASTM C150 Standard Specification for Portland Cement Types I and II.
