    FormationGeologyCompositionPropertiesNamesUsesAdvantagesOther usesAvailabilityLimestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris. It can also be a chemical sedimentary rock formed by the precipitation of calcium carbonate from lake or ocean water. Most limestones form in shallow, calm, warm marine waters. That type of e
  • The role of limestone and calcined clay on the rheological

    The materials used were clinker, calcium sulphate, limestone and calcined clay. Table 1 shows the chemical composition of the materials. The clinker and limestone were ground separately, after which they were sieved with a 149 μm sieve. Commercially available calcined clay from Maoming, China was used after further grinding.
