Types of Portland cement

 

The ASTM has designated five types of portland cement, designated Types I-V.  Physically and chemically, these cement types differ primarily in their content of C3A and in their fineness.  In terms of performance, they differ primarily in the rate of early hydration and in their ability to resist sulfate attack.  The general characteristics of these types are listed:

 

 

Classification

Characteristics

Applications

Type I

General purpose

Fairly high C3S content for good early strength development

General construction (most buildings, bridges, pavements, precast units, etc)

Type II

Moderate sulfate resistance

Low C3A content (<8%)

Structures exposed to soil or water containing sulfate ions

Type III

High early strength

Ground more finely, may have slightly more C3S

Rapid construction, cold weather concreting

Type IV

Low heat of hydration (slow reacting)

Low content of C3S (<50%) and C3A

Massive structures such as dams.  Now rare.

Type V

High sulfate resistance

Very low C3A content (<5%)

Structures exposed to high levels of sulfate ions

White

White color

No C4AF, low MgO

Decorative (otherwise has properties similar to Type I)

 

The differences between these cement types are rather subtle.  All five types contain about 75 wt% calcium silicate minerals, and the properties of mature concretes made with all five are quite similar.  Thus these five types are often described by the term “ordinary portland cement”, or OPC.[reference]
