  Cement A cement is a binding material, used for construction that sets, hardens, and adheres( जुड़ जाना ) to other materials to bind them together. Cements in a general sense are adhesive and cohesive materials which are capable of bonding together particles of solid matter into a compact durable mass. Cement is an extremely fine material having adhesive and cohesive properties which provide a binding medium for the discrete ingredients. Cement is the mixture of calcareous, siliceous, argillaceous and other substances. The cement is a product obtained by pulverizing (to make into a powder form,   पीसना ) clinker formed by calcinating the raw material preliminary( प्रारंभिक ) consisting of Lime (CaO), Silicate (SiO2), Alumina (Al₂O) and Iron oxide (FeO3). Cement is seldom( कभी - कभी ) used on its own, but rather to bind fine aggregate (sand) and coarse aggregate (gravel) together. Cement mixed with fine aggregate produces mortar for masonry, or with fine aggregate and coarse ...
