The Five Ws and One H of Portland Limestone Cement

This article lays out key points about portland limestone cement (PLC) for contractors, producers, and engineers. PLC is a type of cement produced by combining limestone with portland cement clinker and calcium sulfate. The addition of limestone to portland cement production reduces the amount of carbon dioxide emissions. PLC has been recognized in a number of cement standards in North America. It is designed to have a similar compressive strength to portland cement, though it often has a slightly faster rate of reaction and strength development. The performance of PLC and portland cement have been found to be similar, and PLC can be used to replace portland cement in commercial mixtures.
