Home - LC3 - Limestone Calcined Clay Cement

WHAT IS LC3?. LC3 is a new type of cement that is based on a blend of limestone and calcined clay. LC3 can reduce CO2 emissions by up to 30%, is made using limestone and low-grade clays which are available in abundant quantities, is cost effective and does not require capital intensive modifications to existing cement plants.

Emissions from the Cement Industry mbia.edu

 · Cement Emissions. The production of cement releases greenhouse gas emissions both directly and indirectly: the heating of limestone releases CO 2 directly, while the burning of fossil fuels to heat the kiln indirectly results in CO 2 emissions. The direct emissions of cement occur through a chemical process called calcination.

Aggregates

For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse.

Monocarbonate: the presence of fine limestone, whether interground with the cement or present as fine limestone aggregate, is likely to produce monocarbonate (C 3 A.CaCO 3.11H 2 O) as some of the limestone reacts with the cement pore fluid. Other AFm phases that may be present are hemicarbonate, hydroxy-AFm and Friedel's salt.
