General Purpose Cement with Increased Limestone Content

The substitution of a higher content of clinker with limestone will allow for a lower embodied energy and emissions associated with the manufacture of GP cement. Fresh and hardened properties of normal-grade concrete (N20 and N32) prepared with GP cement containing limestone contents in the range of 5 to 12% were investigated.

Cement – Analysis

Clinker is the main ingredient in cement, and the amount used is directly proportional to the CO 2 emissions generated in cement manufacturing, due to both the combustion of fuels and the decomposition of limestone in the clinker production process.. From 2014 to 2018, the clinker-to-cement .

Portland Limestone Cement

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.
