EcoCem® PLC
Concrete Just Got Greener

EcoCem® PLC is a Portland Limestone Cement (Type GUL or Type I) produced using ordinary Portland clinker interground with limestone. EcoCem® PLC is an environmentally responsible alternative to ordinary Portland Cement and can be used for concrete in non-sulfate exposures. EcoCem® PLC meets CSA and ASTM/AASHTO standards specifications for Portland-Limestone Cements. 

EcoCem® PLC is a portland-limestone cement with equivalent performance to Type GU or Type I cement but with a smaller environmental footprint.

EcoCem® PLC is made using the same components as Type GU and Type I cement, but it is processed differently and contains as much as 10% more limestone. By increasing the amount of limestone and decreasing the amount of clinker, Lehigh Cement has reduced the energy required to produce EcoCem® PLC as well as associated emissions. Using innovative technology, Lehigh Hanson has developed EcoCem® PLC as a product which can be substituted directly for normal Type GU or Type I portland cement in general use applications. 

EcoCem® PLC meets the specifications for Type GUL portland-limestone cement in CSA A3000 and CSA A23.1. Type GUL portland cement is referenced in the National Building Code of Canada and is approved for use in British Columbia, Manitoba, Ontario, Quebec, and Nova Scotia. . 

EcoCem® PLC meets all applicable requirements of Type IL under AASHTO M240, ASTM C595 and also meets requirements for ASTM C1157 performance cements. The ACI 318-14 building code references ASTM C595 Type IL cement. ASTM C595 TYPE IL is equivalent to ASTM C150 Type I hydraulic cement in compressive and flexural strength, durability and it is allowed in non-sulfate exposure class S0 (ACI 318-14 Table, the same as ASTM C150 Type I cements.
