cement Definition Composition Manufacture History

Cement in general adhesive substances of all kinds but in a narrower sense the binding materials used in building and civil engineering construction. Cements of this kind are finely ground powders that when mixed with water set to a hard mass.Setting and hardening result from hydration which is a chemical combination of the cement compounds with water that yields submicroscopic

Cement Types Composition Uses and Advantages of

We first discuss cement production and special nomenclature used by cement industrialists in expressing the composition of their cement products. We reveal different types of cement products their compositions properties and typical uses. Wherever possible we tend to give reasons as to why a particular cement type is more suitable for a given purpose than other types.
