Cement is a material withadhesive and cohesive properties which make it capable of bonding mineralsfragments into a compact whole. It can be defined as any substance, which canjoin unite two or more pieces of some other substance together to form a unitmass. It is an inorganic, non-metallic substance with hydraulic bindingproperties, and is used as a bonding agent in building materials. It is a finepowder, usually gray in color that consists of a mixture of the hydrauliccement minerals to which one or more forms of calcium sulfate have been added.Mixed with water it forms a paste, which hardens due to formation of cementmineral hydrates. Cement is the binding agent in concrete, which is acombination of cement, mineral aggregates and water. Concrete is a key buildingmaterial for a variety of applications.
Cement, as used in constructionindustries, which when mixed with water and allowed to set and harden can joindifferent components or members together to give a mechanically strongstructure. Thus cement can be used as bonding material for bricks or for bondingsolid particles of different sizes (rubber masonry) to form a monolith.
