Type 1L Cement: Lower Carbon, Same Confidence
Type 1L Cement is a Portland Limestone Cement, where limestone replaces a portion of the clinker. Less clinker means lower carbon intensity, while general-use performance stays exactly where you need it. This cement also meets ASTM C595 specifications.
Lower Carbon Without the Trade-Off
Specifiers reach for Portland Limestone Cement because it does the everyday work of a general-use cement with a reduced carbon footprint. The difference lies in what it takes to make it, not in how it performs.

Why it belongs in the mix
Reduced clinker content, which lowers the carbon intensity of the cement.
General-use performance across a broad range of concrete applications.
Familiar handling and placement, with no relearning required on site.
A straightforward route to lower carbon targets on a project.
Held to the same quality control and verification as every product we make.
