OneCem® Portland Limestone Cement Materials

2020-7-25  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 CO 2 emissions by five to 10 percent per ton of cement.

The Advantages of Portland-Limestone Cement|

2014-8-12  So what is portland-limestone cement? PLC is a slightly modified version of portland cement that improves both the environmental footprint and potentially the basic performance of concrete. It is now described in ASTM and AASHTO specifications and is used just like traditional portland cement in
