Cement is a finely powdered substance made up of limestone and other minerals that serve as a binding element when it is added to water, sand, and aggregates. It is the backbone of contemporary construction, applied to everything, including towering structures, modern highways, bridges, and countryside housing.
There are more than 60 cement factories located in the country, including a great number of brands that can be selected; that is why it is important to select the best type of cement for your use case.
In this blog, we will discuss all the types of cements that are available in the Nepali market, along with their use cases, advantages, and how to choose the best cement for your needs.
What are the types of cement available in the market?
As the country is increasingly experiencing the need to have a sustainable and stronger construction of buildings, a variety of cements have been introduced that can serve various needs of structures and environmental circumstances.
Here are some of the most popular types of cement available in the market:
1. Ordinary Portland Cement (OPC)
Ordinary Portland cement, also referred to as OPC, is one of the commonly used cements worldwide and in Nepal. It is produced by pulverization of clinker and gypsum, which makes this cement highly strong, presentable, with rapid setting, and is best in high-load structural construction.
Use Cases:
OPC is perfect for high-rise tower constructions, where the early strength and the load-bearing capability of cement are essential for buildings.
- It is frequently applied in concrete pavements and roads and provides a durable and strong surface.
- It is widely used in foundation works, particularly with heavy-load structures.
- It is suitable for precast concrete products as it dries out fast and evenly.
Advantages:
- This cement offers substantial compressive strength in a short period, which guarantees structural stability at the early stages of construction.
- It is suited for rapid construction ventures that require a rapid setting period.
- This cement is compatible with standard building practice, which makes it versatile and easy to implement.
- This provides a dense and solid surface finish, which increases the life cycle of a structure.
Examples: Jagadamba Cement OPC, Shivam Cement OPC, and Udayapur OPC Cement are the top brands of OPC and are known for their quality and uniformity, and ISI licensing.
2. Portland Pozzolana Cement (PPC)
Portland Pozzolana Cement (PPC) is a blended cement produced by mixing OPC clinker with pozzolanic properties like fly ash or volcanic ash. It sets more slowly and is superbly long-lasting and chemical-resistant.
Use Cases:
- PPC has become popular in the residential construction of buildings due to durability and affordability.
- It is used in structures like dams and bridges, providing prolonged ability in weathered site environments.
- It is recommended for marine construction because of its superior resistance to moisture and other chemicals.
- It is best used in sewage and water treatment plants since it does not degrade easily.
Advantages:
- It provides increased long-term strength and operation in harsh conditions.
- It minimises environmental effects through the use of fly ash as an industrial by-product.
- This cement increases the chemical and sulfate resistance of the structure and therefore enhances its life.
- It is cost-efficient when concrete is mass-produced, so it helps to save funds in mass constructions.
Example: The most recognized PPC brands of cement in Nepal are Hetauda Cement PPC, Arghakhanchi Cement PPC, and Ambe Cement PPC.
3. Sulfate-Resistant Cement (SRC)
Sulfate-Resistant Cement is engineered to combat sulfate attacks in chemically aggressive environments. It has a lower percentage of tricalcium aluminate (C3A), which is the ideal cement to be used around regions whose soil or groundwater contains a high amount of sulfates.
Use Cases:
- It is used in marine structures when the surrounding environment poses extreme wear due to saltwater.
- They are very suitable in sewage treatment plants where the structure can be destroyed by a lot of sulfate, which can cause damage to ordinary cement.
- It is appropriate in the foundations that are in the sulfate-rich soils, like in the Terai areas.
- It is often used in docks and harbor construction, where the structure has to be resistant to sulfate attack.
Advantages:
- It provides durability to sulfate attacks, leaving the structure intact.
- It enhances the life of structures in chemical aggression or wet conditions.
- It is built to be durable and used in the infrastructures constructed with durability in mind, and mainly located in areas where the soil conditions are poor.
Although SRC is the recommended option in the sulfate-prone areas of Nepal, particularly in the southern plains of Nepal, companies usually do not produce this cement in mass.
4. Rapid Hardening Cement (RHC)
Rapid Hardening Cement is a specially prepared cement that sets more quickly than OPC. It is also created through fine grinding of the clinker so that the cement can be made more reactive and thus most suitable when there are time limitations in construction.
Use Cases:
- This is suitable in road works where a quick breakdown to open up the service is needed.
- These are cement are common during bridge construction, particularly in cases where there is a strict project schedule.
- This cement is appropriate for precast concrete parts when it is necessary to extract formwork early.
- It is used in emergency construction jobs that need rapid setting as well as rapid strength gain.
Advantages:
- It offers fast set and early strength, so that there is a minimal delay to continue construction.
- It saves the total time spent on construction, and thus it is suitable when some projects need to be completed on time.
- It becomes cost-effective in terms of saving on form work and labor as they can complete the structures within a shorter time.
- RHC is useful in infrastructure work in Nepal, where the dry seasons are too short to build up rail and road works in the hills and the Terai.
5. Portland Slag Cement (PSC)
Portland Slag Cement (PSC) is a blended cement, which is made by combining OPC clinker and granulated blast furnace slag, a residue of steel making. It has been known to be environmentally friendly and strong in hostile conditions, even in the long run.
Use Cases:
- It is mostly used on marine and coastal buildings that require resistance to chloride attack.
- This cement is perfect in areas like infrastructure with aggressive weather, like industrial zones.
- It is recommended in industrial buildings that are intended to be used in the long run, and must be long-lasting and must withstand chemicals.
Advantages:
- It has very good resistance to chlorides and sulfates, and as such is durable in adverse conditions.
- This cement generates less heat of hydration and thus minimizes cracking of the mass concreting.
- It is regarded as a green building solution for sustainable building.
Although PSC remains less prevalent in Nepal compared to OPC and PPC to date, it has been trending among developers who are environmentally conscious and mega infrastructure initiatives.
6. White Cement
White Cement is a highly processed type of OPC, and it is produced with raw materials with low contents of iron oxide and manganese to create its ivory-like color. It is not structurally strong, but it is significant in architectural and decorative purposes.
Use Cases:
- It is commonly used as a decorative ornamentation, terrazzo floorings, and designer tiles.
- It is also used in the finishes of walls and tile adhesives, giving a polished, clean look.
- Ideal for marble grouts, matching aesthetics and ensuring bond strength.
- Common in architectural projects, where color and visual appeal matter.
Advantages:
- It is aesthetically pleasing to the eye, with a clean and bright white color.
- It provides reflective and illuminating surfaces, improving the design visibility.
- It has good strength and high-binding capacity, just like OPC.
The white cement used in Nepal is mostly imported and hence costlier, and is mostly utilised in expensive residential homes, hotels, and commercial buildings where the design and finishing are the primary concern.
