cement chemical formula

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 atetra-calcium aluminoferrite (4CaO · Al 2 O 3 Fe 2 O 3). In an abbreviated notation differing from the normal atomic symbols, these compounds are designated as C 3 S, C 2 S, C 3 A, and C 4 AF, where C stands for …
