15 types of cement which our company do produces and supplies

Cement is a binding material which makes a bond between aggregates and reinforcing materials together. With the development of technology, quality and types of cement have also developed. So there are different types of cement for different construction works.

Types of Cement

Cement is mainly classified into two categories depending on the hardening and setting mechanism. These are-

Hydraulic Cement

Non-hydraulic Cement

Along with these main types, depending on the composition and characteristics there are many types of cement.  Followings are the other cement types:

Ordinary Portland Cement (OPC)

Portland Pozzolana Cement (PPC)

Rapid Hardening Cement

Quick Setting Cement

Low Heat Cement

Sulphate Resisting Cement

Blast Furnace Cement

High Alumina Cement

White Cement

Colored Cement

Air Entraining Cement

Expansive Cement

Hydrophobic Cement

Nomenclature Differences

In the US, three separate standards may apply depending on the category of cement. For portland cement types, ASTM C150 describes:

Cement Type          Description
Type I                      Normal
Type II                     Moderate Sulfate Resistance
Type II (MH)             Moderate Heat of Hydration (and Moderate Sulfate Resistance)                            
Type III                    High Early Strength
Type IV                    Low Heat Hydration
Type V                     High Sulfate Resistance

For blended hydraulic cements – specified by ASTM C595 – the following nomenclature is used:

Cement Type           Description
Type IL                    Portland-Limestone Cement
Type IS                    Portland-Slag Cement
Type IP                    Portland-Pozzonlan Cement
Type IT                    Ternary Blended Cement

In addition, some blended cements have special performance properties verified by additional testing. These are designated by letters in parentheses following the cement type. For example Type IP(MS) is a portland-pozzolan cement with moderate sulfate resistance properties. Other special properties are designated by (HS), for high sulfate resistance; (A), for air-entraining cements; (MH) for moderate heat of hydration; and (LH) for low heat of hydration. Refer to ASTM C595 for more detail.

However, with an interest in the industry for performance-based specifications, ASTM C1157 describes cements by their performance attributes: 

Cement Type         Description
Type GU                  General Use
Type HE                  High Early-Strength
Type MS                 Moderate Sulfate Resistance
Type HS                  High Sulfate Resistance
Type MH                  Moderate Heat of Hydration
Type LH                   Low Heat of Hydration
