All Items Need to be Known on Limestone Powder

Sep 02, 2021 Limestone is a member of the sedimentary rock family and is usually gray or black. Its chemical composition is mainly CaO, generally 45% to 55%, followed by a few of MgO, SiO 2 and Al 2 O 3.. The mineral composition of limestone rock is mainly calcite or calcareous bioclasts (such as shells or biological bones, which are also composed of calcium carbonate), followed by dolomite, clay, silt
