The commonly used cements in well applications are API Class A, C, G, and H. These cements, as produced in accordance with API Spec. To extend the thickening time beyond that obtained with a neat (cement and water without additives or minerals) API-class cement slurry, additives known as .
Gypsum cement is a blend of API Class A, C, G, or H cement and a hemihydrate form of gypsum (CaSO 4 •½H 2 O). Gypsum cements are commonly used in low-temperature applications for primary cementing or remedial cementing work. This combination is particularly useful in shallow wells to minimize fallback after placement.
Composition of cement engr.psu.edu. Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration.This is a complex process that is best understood by first understanding the chemical composition of cement.

A slurry of Portland cement in water is used in wells because it can be pumped easily and hardens readily, even under water.
The heating that occurs in the kiln transforms the raw materials into new chemical compounds. Therefore, the chemical composition of the cement is defined by the mass percentages and composition of the raw sources of lime, iron, silica, and alumina as well as the temperature and duration of heating.

Performance testing has proven to be the most effective in establishing how a slurry will behave under specific well conditions. There is no direct means of predicting cement performance from the properties of cement, and no technique has yet been established that would correlate cement composition and cement/additive interaction with performance.

Cement composition and classification petrowiki ... This cement has a low C3A content so as to avoid sulphate attack from outside the concrete. Otherwise the formation of calcium sulphoaluminate and gypsum would cause disruption of conrete due to an increase in volume of resultant compounds.
Cement, as a binding material, is a very important building material. Almost every construction work requires cement. Therefore, the composition of cement is a matter of great interest to engineers. For understanding cement composition, one must know the functionality of Cement ingredients.
There are various types of cement used in concrete construction. Each type of cement has its own properties, uses and advantages based on composition materials used during its manufacture. Ordinary Portland cement is the most widely used type of cement which is suitable for all general concrete ...
