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 (otherw
