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.

Limestone - Sedimentary rocks

Limestone with a significant amount of clay minerals is known as marl. Tempestite is a storm deposit. Limestone bed was severely disturbed by sea waves in shallow water, but the broken off pieces redeposited quickly and lithified again as a brecciated limestone. .

Claystone. Claystone, hardened clay. Some geologists further restrict the term to a sedimentary rock that is composed primarily of clay-sized particles (less than 1/256 millimetre in diameter) and is not laminated or easily split into thin layers; such rocks that show cleavage roughly parallel to the bedding plane often are classed as clay...

Rock, limestone and clay - teara.govt.nz

Raw materials. Rock (crushed into aggregate), limestone and clay are the bulk products that dominate New Zealand's industrial mineral output. Millions of tonnes are dug, blasted and gouged from the earth each year. Since the 1950s they have accounted for between one-third and two-thirds of the value of mined and quarried materials.

Quantifying the Composition of Limestone - chem21labs

Limestone is composed of the mineral calcite, better known to chemists as calcium carbonate, small amounts of clay, silt, chert (silica, SiO 2), and dolomite (calcium-magnesium carbonate, CaMg[CO 3] 2).2 To be called limestone, the rock has to have a composition of over 50% dolomite and calcite, though the exact percentages vary widely.

Rocks with a more complex chemical composition, such as shale (the mineral clay), however, undergo many compositional, and textural changes.
