Portland cement is one of the most used materials on earth. Its annual production is responsible for approximately 7% of global carbon dioxide (CO 2) emissions.These emissions are primarily associated with (1) the burning of fossil fuels to heat cement kilns and (2) the release of CO 2 during limestone calcination. One …

These two main components are generally limestone and clay or limestone and marl. Lime component Limestone. Calcium carbonate (CaC03) is wide spread in nature. Calcium carbonate of all geological formations qualifies for the production of Portland cement. The purest grades of limestone are calcspar (calcite) and aragonite.

At this maximum level, Type IL PLC reduces the CO2 footprint of concrete by 10%. This is highly significant considering that more than 400 million cubic yards of concrete were produced in the U.S. during 2022. Additionally, PLCs can be used to further reduce concrete's carbon intensity through similar use of supplementary cementitious ...

Portland-limestone cement can contain from 5% to 15% limestone along with the clinker. To assure similar performance in concrete, manufacturers optimize PLCs by grinding them a bit finer than portland cement. The limestone particles can pack closer together to tighten the concrete matrix and their finer grind makes them slightly more reactive.
