Cement The major cements: composition and properties

Chemical composition Portland cement is made up of four main compounds: tricalcium silicate (3CaO SiO 2), dicalcium silicate (2CaO SiO 2), tricalcium aluminate (3CaO Al 2 O 3), and a tetracalcium aluminoferrite (4CaO Al 2 O 3 Fe 2 O 3)Portland cement gets its strength from chemical reactions between the cement and water The process is known as hydration This is a complex process that is best understood by first understanding the chemical composition of position of cement Pennsylvania State UniversityChemical Composition of Cement The raw materials used for the manufacture of cement consist mainly of lime, silica, alumina and iron oxide These oxides interact with one another in the kiln at high temperature to form more complex compoundsChemical Composition of Cement
