2013-1-9 · Manufacture of PLC Limestone Cement has been developed to exhibit “equivalent performance” compared to GU cement Performance to-date has been equivalent Equivalent initial reactivity (set time, 1-day) Equivalent 28-day strength Equivalent durability (freeze/thaw, salt scaling, etc.) Equivalent performance is achieved by optimizing the PLC with
Limestone is important because of its use in the cement industry, and deposits are fairly widespread. North Africa is a particularly important source. North Africa is a particularly important source. In western Africa a belt of limestone runs from the Central African Republic to the Atlantic coasts, with major outcrops in northern
There still seems to be some confusion about whether fine limestone in cement (up to about 5% as permitted by eg: US and European standards) is an inert filler, or whether it is chemically reactive and contributes to the cement hydration products.

Portland‐Limestone cement (PLC) is a more sustainable building choice than regular Portland cement, but just as strong and durable: With up to 15% of the clinker used to produce regular Portland cement replaced by limestone, PLC manufacturing generates significantly lower greenhouse gas emissions and up to 10% fewer CO2 emissions.
In the cement pastes incorporating 15% limestone, evidence for the presence of small amounts of thaumasite, which increased slowly with time, was observed in XRD patterns obtained after 196, 224, 252, 280, 308, 336, and 364 days.
2014-8-12 · The concrete industry has been getting beat up for the past decade over the large carbon footprint of cement, and it’s true that cement manufacturing releases a significant amount of carbon dioxide into the environment. So if cement manufacturers come up with a way to improve concrete
