[PDF] Twostep Homogenization of Poroelastic .

The microstructure of oolitic limestones generally exhibits an assemblage of grains (oolites) surrounded by a matrix. Grain and matrix are linked via the interfacial transition zone (ITZ). Pores exist in these three material phases (oolite, ITZ and matrix). A twostep homogenization method is proposed. The first step consists of upscaling the properties of each porous phase (i.e. porous oolite

Ground Calcium Carbonate / LimestoneHosokawa Micron

Limestone, which is primarily calcium carbonate, is a sedimentary rock made from the minerals calcite or aragonite. A large portion of limestone is made from the skeletal remains of sea creatures and organisms. Ground Calcium Carbonate (GCC) differs from Precipitated Calcium Carbonate (PCC) in that the GCC is formed directly from grinding limestone rock.
