Chemical Composition of Cements
In considering the value of a cement or fireclay, it must be remembered that the mere chemical composition is by no means the sole guiding point. In the case of a cement the degree of fineness, tensile strength, and other points also require determination ; therefore the necessary tests may be subdivided into two classes — chemical and mechanical.

Cement is the chief ingredient in cement paste – the binding agent in portland cement concrete (PCC).It is a hydraulic cement that, when combined with water, hardens into a solid mass. Interspersed in an aggregate matrix it forms PCC. As a material, portland cement has been used for well over 175 years and, from an empirical perspective, its behavior is wellunderstood.
