9 Types of Portland Cement and their Applications

Type IV This type of Portland cement is designed to reduce the heat released during hydration. This is achieved by reducing the percentage of C 3 A in the cement. However, this type has a lower final and initial strength as compared to Type I. It is suited for the construction of massive structures with a low surface-to-volume ratio, like,3.8 - Types of Portland Cement - Northwestern University,Type IV cement is designed to release heat more slowly than a Type I cement, meaning of course that it also gains strength more slowly. A slower rate of heat release limits the increase in the core temperature of a concrete element.MATERIAL SAFETY DATA SHEET,MATERIAL SAFETY DATA SHEET 1.
