OneCem® Portland Limestone Cement

Performance and workability—with a lower carbon footprint.

Our Portland Limestone Cement offers the same level of performance and workability you expect from standard Type I and Type II cements. But, because it’s manufactured with quality limestone, it uses less clinker than the traditional manufacturing process and reduces CO2 emissions by five to 10 percent per ton of cement.

Why’s that important? In the United States alone, the building sector is responsible for nearly half of all US CO2 emissions, and design and construction professionals are looking for ways to lower the industry’s carbon footprint. From manufacturing raw materials to designing automated controls, every piece of the building cycle is critical. Together we can set a new standard for building responsibly — without sacrificing performance.


Discover its Benefits

Portland Limestone Cement can be used seamlessly as a direct substitution for ordinary Portland cements in mix designs. It produces similar results – strength, workability and durability, as well as color and aesthetic – when compared to standard Portland Type I and II cements.

Hydrates with synergies that enable enhanced setting and strength performance, especially in combination with supplementary cementitious materials. Can improve concrete sustainability and performance equal to or better than ordinary Portland cements.

Design and construction professionals can take advantage of using Portland Limestone Cement and know that they’re making an impact on the environment. Add slag or fly ash to further enhance performance, and further reduce your carbon footprint.
