Cement chemist notation

Cement chemist notation (CCN) was developed to simplify the formulas which cement chemists use on a daily basis. It is a sort of "short hand" way of writing the chemical formula of oxides of calcium, silicon, and various metals. Below is a list of all of the abbreviations used:

CCN	Actual Formula
C	CaO
S	SiO2
A	Al2O3
F	Fe2O3
T	TiO2
M	MgO
K	K2O
N	Na2O
H	H2O
	CO2
	SO3

These oxides are used to build more complex molecules such as:

Hydration products are more complicated, because many of the products have nearly the same formula and some are solid-solutions with overlapping formula. Some examples are below:

CSH	2(CaO) • SiO2 • 0.9-1.25(H2O) and/or CaO • SiO2 • 1.1(H2O) and/or 0.8-1.5(CaO) • SiO2 • 1.0-2.5(H2O) and more!
CAH	This is even more complex than CSH
AFt	C3A3H30-32
AFm	C2AH12
