Portland Cement

We had exported cement of all kinds from 32.5 - 42.5 - 52.5. We do know that your esteemed company is a big company and you are looking for long term partnership in Vietnam for cement supply. We had export our cements (in bulk, in 40 kilo, 50 kilo and jumbo bag, container etc., ) directly or via oversea partners

We hope to have chance to cooperate with you and your esteemed company in supplying cement and other building materials to oversea markets for our mutual benefits.

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

Sulte Resisting Cement

Blast Furnace Cement

High Alumina Cement

White Cement

Colored Cement

Air Entraining Cement

Expansive Cement

Hydrobic 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
