EcoCem®PLC is a Portland Limestone Cement (Type GUL or Type IL) produced using ordinary portland clinker ground with limestone. Compared to CSA Type GU and ASTM Type I-II/AASHTO Type I portland cement, EcoCem®PLC contains as much as 10% more limestone using the same components and yields – with equivalent performance to ordinary 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, making EcoCem®PLC the green alternative to ordinary cement with a smaller environmental footprint. Additionally, EcoCem®PLC can be used in concrete that will be exposed to moderate sulfate conditions.
PLC products have been well established in Europe for decades and Lehigh Hanson, together with their parent company Heidelberg Cement, is proud to lead the introduction of this sustainable product to North America. EcoCem®PLC is a cement which can be substituted directly for normal Type GU or Type I-II portland cement in general use applications.
