Cement - Encyclopedia Britannica Britannica

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 - History of cement Britannica

Cement - Cement - History of cement: The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2,000 years ago and of subsequent construction work in western Europe.

Cement - Encyclopedia Britannica Britannica

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 C3S, C2S ...

Cement - Cement testing Britannica

Cement - Cement - Cement testing: Various tests to which cements must conform are laid down in national cement specifications to control the fineness, soundness, setting time, and strength of the cement. These tests are described in turn below. Fineness was long controlled by sieve tests, but more sophisticated methods are now largely used. The most common method, used both for control of the ...
