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
