Proportioning Concrete Mixtures with PLC

Start with the same amount of PLC to replace portland cement, and then test the mixture to confirm fresh and hardened properties. PLC is generally designed to replace portland cement at the same cement content to result in comparable concrete performance. The production of PLC includes controlling cement fineness, particle size distribution, and sulfate content to provide similar performance when compared to portland cement made from the same clinker.

​

Research studies and real-world concrete placements have demonstrated that by following well-documented mixture design and quality control practices, concretes made using PLC can perform similarly to concretes made with portland cement. Maintaining concrete behavior requires additional trial batching as when changing from one source of cement to another.
