What are the types of Portland cement?
Majorly Portland cement produced by cement companies in India is classified into 2 categories, ASTM type of portland cement and ASTM type of blended cement Type of ASTM portland cements are as follows: Type I general purpose, Type II moderate sulfate resistance, Type III high early strength, Type IV, a low heat of hydration (slow reacting), Type V high sulfate resistance. The differences between these cement types are rather subtle. All five types contain about 75 wt% calcium silicate minerals, and the properties of mature concrete made with all five are quite similar. Thus these five types are often described by the term “ordinary portland cement”, or OPC. Type of ASTM portland cement are as follows: Portland Slag Cement, portland pozzolana cement and ternary blended cement. Blended cements are produced by uniformly intergrinding or blending two or more types of fine materials. For more information, visit www.emamicement.com or call us on 18001022008.
