How many types of cement. Oil Well Cement. In modern type of expansive cements, source of reactive aluminate are used that combine with sulfates of Portland cement to form expansive ettringite. These types of cement have he quality to expand slightly with time. Answer. Type IV For use when low heat of hydration is required (Low Heat Cement). Expansive Cement. Expansibility: It can be divided into: Expansive cement, and Self-stress cement. A list of some commonly used cement is described in this section: Ordinary Portland cement. 5. The controlled formation of ettringite in early days after placing of concrete is used to achieve a shrinkage compensating effect. These cements are increasingly used for the repair of concrete structures. Concrete made up of OPC shrinks while setting due to loss of free water. S Type Expansive Cement.
