Cement is the most widely consumed commodity after water. It is the main component in the construction and production of infrastructures for building and development of residential buildings, public buildings, and water and sewage systems.
Due to its importance and properties, most countries manufacture their own cement locally.
Raw material = a combination of limestone and clay.
Clinker = a new material which is the product of a chemical process of baking the raw material in a kiln at extremely high temperatures.
Cement = ground clinker with added gypsum and minerals.
Concrete = cement mixed with gravel, coarse sand and water, which turns into a building material second to none in terms of convenience, speed of application and strength.
Reinforced concrete = a composite material, obtained by adding steel meshes or rods or other elastic materials to the concrete. This is an extremely strong material, and due to its capacity to resist different types of stress it plays a key role in the construction of buildings. Another factor behind the successful combination of these two materials – concrete and steel – is their almost identical thermal expansion coefficients. As a result, when a reinforced concrete component undergoes a drastic change of temperature, there are no warping or cracks. Concrete also protects the steel against corrosion. Reinforced concrete is the main building material for residential, commercial and industrial buildings.
