Tour Topic:

EcoCem®PLC is a Portland Limestone Cement (Type IL) produced using ordinary portland clinker ground with limestone and is approved by the MD SHA. Compared to ASTM Type I and Type I/II portland cement, EcoCem®PLC contains as much as 10% more limestone using the same components and yields – with equivalent performance to Type I and Type I/II portland cement.

Using innovative technology to increase the amount of limestone and decrease the amount of clinker, Lehigh Cement has reduced both the energy required to produce EcoCem®PLC and associated emissions; the green alternative to ordinary cement with a reduction in the global warming potential (GWP). The tour includes seeing the technology used to manufacture Type 1L cement.
