But this cement is very useful for medium-sized construction. Together, they account for more than 92% of the total cement production. The most common chemical constituents used to classify Portland cement are C3A (tricalcium aluminate), C3S (tricalcium silicate), C4AF (tetracalcium aluminoferrite), and a concept called the ‘heat of hydration’. There are a number of uses for cement, and since each use is unique, it needs a different type of cement. One such synonym is the slug. Type IV cement generates less heat during hydration and curing than ordinary Type I portland cement. However, this type has a lower final and initial strength as compared to Type I. Precast concrete casting (Beams, Colums etc) Cement connects sand and clay for various purposes. Since that time, a number of developments and improvements have been made in the production process and cement properties. It is commonly used for general construction, especially when making precast, and precast-prestressed concrete that is not to be in contact with soils or ground water.
