· Portland cement is about 91 percent clinker, while PLC is just 83 percent clinker. Limestone content is up to five percent in ordinary Portland cement (OPC), but as high as 15 percent in PLC. PLC blends appear in residential, commercial and government projects. Specifiers list PLC concrete for bridges, pavements and a wide variety of structures.
· The primary sustainability effect of using limestone as an ingredient in blended cements at levels of 5% to 15% by mass is that less clinker has to be produced for an equivalent amount of cement, and therefore less energy is consumed and CO2 emissions and other greenhouse gases are reduced. This can be seen in Table 2.
