Cement Technology Course (3/5) geological point of view

Argillaceous Rocks These are the sources for SiO2, Al2O3 and Fe2O3 They include claystones, siltstones, shales, mudstones and even marls. Claystone is a clastic sedimentary rock. It is composed of very fine particles (clay sized, less than 1/256 mm) which have become cemented into a hard rock. Claystone is distinguished from a mudstone by the […]

Raw Material Characterization Carbonate Rocks The carbonate rocks make up 10 to 15% of sedimentary rocks. They largely consist of two types of rocks. Limestones which are composed mostly of calcite (CaCO3) or high Mg calcite [(Ca,Mg)CO3], and Dolostones which are composed mostly of dolomite [CaMg(CO3)2]. Because carbonate minerals in general are soluble in slightly […]
