Cement
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)
