    Full Article. 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 paste setting time is affected by a number of items including: cement fineness, water-cement ratio, chemical content (especially gypsum content) and admixtures. For construction purposes, the initial set must not be too soon and the final set must not be too late. Normally, two setting times are defined: Initial set. Occurs when the

    Dec 17, 2015 I- Introduction. The cement is used as a sealing material while drilling an oil and gas well. Pumping cement behind the casing provides a barrier to the fluids flow from or into the formation, and bonds the casing to the formation. This is called a primary cement job. Cement is also pumped for other reasons like sealing off perforated casing or

  • Cement - History of cement | Britannica 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
