Basic Things you should know about Cement - Basic Civil

Types of cement; Various types of cement are possible by blending different proportions of gypsum, clinker, and other additives. Cements that are used for construction fall into two main categories based on cement properties, hydraulic or non-hydraulic. In addition to the two main cement forms, there are several different forms of hydraulic cement.

What is Cement? Types of Cement - The Concrete Network

Type 1 - Normal portland cement. Type 1 is a general use cement. Type 2 - Is used for structures in water or soil containing moderate amounts of sulfate, or when heat build-up is a concern.. Type 3 - High early strength. Used when high strength are desired at very early periods. Type 4 - Low heat portland cement. Used where the amount and rate of heat generation must be kept to a minimum.
