Cement
Cement - Ancient, Roman, Production: The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2,000 years ago and of …

Environmental Benefits. Portland Limestone Cement is environmentally friendly, making it a smart option when building sustainably. The addition of limestone allows for a reduction in clinker, one of the main contributors of CO 2 in cement. This clinker reduction results in reduced greenhouse gas emissions and a smaller carbon footprint.

Portland Limestone Cement FAQ
The compressive strength will be similar to what you are achieving now, with minimal impact to air content, slump and other properties. 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).
