Catalog excerpts

Lafarge Portland Limestone Cement (PLC) is an interground cement with a typical limestone content of 10-20%. Thanks to this level of limestone PLC has lower embodied CO2 than Portland Cement (PC). PLC can be used as a replacement for Portland Cement (PC) and meet the requirements for Design Chemical Classes one and two. PLC can’t be blended with GGBS or PFA to meet the requirements for Design Chemical Classes three & four. The fresh properties of PLC produced concrete are similar to that of a PC produced concrete.
