More Information About 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 джип туры по Большому Кавказу, 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 in bellow table.
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) |
