Cement The major cements: composition and properties

Cement Cement The major cements: composition and properties: Portland cement is made up of four main compounds: tricalcium silicate (3CaO · SiO2), dicalcium silicate (2CaO · SiO2), tricalcium aluminate (3CaO · Al2O3), and a tetra-calcium aluminoferrite (4CaO · Al2O3Fe2O3). In an abbreviated notation differing from the normal atomic symbols, these compounds are designated as

Chemical Composition of Cement Construction How

05/04/2020· In addition to the main compounds listed in there exist minor compounds, such as MgO, TiO 2, Mn2O3, KP, and Na2O; they usually amount to not more than a few per cent of the mass of cement. Two of the minor compounds are of interest: the oxides of sodium and potassium, and K 2 0,known as the alkalis (although other alkalis also exist in cement).

POZZOLANIC CHARACTERISTICS OF A NATURAL RAW MATERIAL

Cement is a material that can bind solid particles e.g. gravel, sand, aggregate etc. within a compact structure. A variety of materials may exhibit cementitious properties. In the concrete industry, hydraulic cements such as Portland cement have the ability to set and harden in the presence of water. They are usually manufactured from calcareous raw materials containing silicates, aluminates
