what iscement?:Cementis the mostusedconstructionmaterialin the world that has both adhesive and cohesive properties due to which it can make bonding and bind particles of solid matter into a compact durable solid mass. It is obtained by mixing limestone and clay, burning them, and grinding to a fine powder. Here we discuss different types ofCement.

The most important raw materials for the production of cement are limestone, clay, and marl. Mixed with water, cement serves as an adhesive to bind sand, gravel, and hard rock in concrete. Cement hardens both in the air and under water, and remains in its hardened state once reached. Cement is usually available in the form of a homogeneous bulk dry good.

Concrete is used for a large variety of constructional purposes. Mixtures of soil and portland cement are used as a base for roads. Portland cement also is used in the manufacture of bricks, tiles, shingles, pipes, beams, railroad ties, and various extruded products. The products are prefabricated in factories and supplied ready for installation.

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.

On the other hand, hydraulic cement is mainly made up of silicates and oxides: Belite (2CaO·SiO 2 ); Alite (3CaO·SiO 2 ); Tricalcium aluminate/ Celite (3CaO·Al 2 O 3) Brownmillerite (4CaO·Al 2 O3·Fe 2 O 3)

Carib Cement manufactures, distributes, and exports high-quality Portland cement using one hundred percent Jamaican raw material. The raw material used in the manufacturing process are all mined within ten miles of the plant. The company exports its surplus gypsum and boasts of its own ports for the shipment abroad of both its cement and gypsum.

Limestone comprises 95% of core rawmaterialforcementproduction. No wonder then that thecementsector governs demand, supply and pricing of limestone (as well as coal) to some extent.
