Hydraulic cements (eg. Portland cement) harden because of hydration chemical reactions that occurs independently Of the mixture’s water content; they can harden even underwater or when constantly exposed to wet weather. The chemical reaction that results when the anhydrous cement powder is mixed with water produces hydrates that are not water-soluble. Non- hydraulic cements (eg. Lime and gypsum plaster) must be kept dry in order to retain their strength.

The most important use of cement is the production of mortar and concrete The bonding of natural or artificial aggregates to form a strong building material that is durable in the face of normal environment effects. • Cement is made by heating limestone (calcium cabonate), with small quantities of other materials (such as clay) to 1450ͦC in a kiln, in aprocess known as calcination, whereby a molecule of carbon dioxide is liberated from the calcium carbonate to form calcium oxide,or quicklime,which is then blended with the other materials that have been included ih the mix.
