Sand includes sediment grains ranging in size from 2mm to 0.625 mm. Silt is the name of a sediment grain that range in size from 0.625 mm to 0.0039 mm. Mud is the smallest grain size and is also known as clay. It is important to distinguish the grain size called clay from the mineral called clay.
What Are Sedimentary Rocks? Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks. Clastic sedimentary rocks form from the accumulation and lithification of mechanical weathering debris. Examples include: breccia, conglomerate, sandstone, siltstone, and shale. Chemical sedimentary …
The ingredients are usually extracted from limestone, clay, marl, shale, chalk, sand, bauxite, and iron ore. These raw materials are crushed and ground into a fine powder at the cement plant.

Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.
Because of impurities such as clay, sand, organic remains, iron oxide, and other materials, many limestones exhibit different colors, especially on weathered surfaces. Limestone may be crystalline, clastic, granular, or dense, depending on the method of formation, and crystals of calcite, quartz, or dolomite may line small cavities or geodes in ...
Generally these additives are sand and iron ore, but other types of raw materials are used as well, such as marl, shale and fly ash. Cement composition will vary from plant to plant depending on the quality of the limestone in that specific quarry and the availability of additives in that area.
The most important raw material used in the cement industry is limestone. Limestone is rich in calcium carbonate and serves as the primary component in producing cement clinker, which is then ground to …
