When planning a construction project, whether it is a home, a commercial building or even a renovation, cement is the most crucial factor in construction. Though, cement is of many types, it is imperative to use the right type- one aspect many builders fail to consider. Every area of construction requires a specific type and content of cement. The correct type determines the strength, durability and longevity of the structure- something that should never be compromised.
Choosing the right type of cement is important because every kind is formulated with certain ingredients that are best suited for a specific use or application. Inappropriate type could lead to lessened durability, cracks, wasted materials and unexpected expenses.
Types of Cement
The most common types of cement used in construction are-
1. Ordinary Portland Cement (OPC)
OPC is ideal for heavy-load structures such as roads, bridges, runways, and multi-storey buildings. It provides high strength in the early construction stages, which is required in fast-paced projects.
This type comes in three grades—33, 43, and 53—based on the level of compressive strength achieved after 28 days of setting.
JK Super OPC 43-grade cement offers sulphate and chloride resistance to enhance durability and increase compressive strength, and low alkali content for increased protection.
JK Super OPC 53-grade is a highly demanded grade of cement, known for its early superior strength and fineness.
2. Portland Pozzolana Cement (PPC)
PPC is made with natural ingredients such as fly ash and clay, which makes it extremely environmentally friendly. Its low heat of hydration property enhances durability and reduces cracking due to excessive heat. It is also extremely resistant to alkali, moisture, sulphate and chemicals- ideal for residential buildings, plastering and masonry work.
JK Super Cement – PPC Cement is known for its high durability and long-lasting functionality, and finishing. Resistant to corrosion and offering strength, it is ideal to be used in the construction of the foundation.
3. Portland Slag Cement (PSC)
PSC offers high resistance against chloride and sulfate – making it best suited for humid and coastal regions. Formulated to withstand stressful environments, PSC comes with increased durability.
JK Super PSC ensures long-term durability, formulated with the best quality clinker and limestone. Its chemical-resistant and eco-friendly properties make it a highly demanded cement in the construction of foundations and slabs.
4. Sulphate-Resisting Cement (SRC)
SRC is a specialized cement type formulated- as the name suggests- to offer resistance against sulfate that can compromise the strength of concrete. Hence, in areas where the soil is high in sulfate content, SRC is best suited.
Factors To Consider When Choosing Cement
Choosing the right type of cement is one thing, but it is also important to consider certain parameters when making the choice.
1. Type of Construction- Different types of cement are suited to different types of construction. For example, in residential construction, PPC is preferred due to its finishing, durability and resistance to moisture, alkali and sulphate, while in commercial constructions, PSC or OPC due to their load-taking capacity and ability to withstand harsh weather conditions.
2. Environment- The environmental conditions play a significant role in the type of cement to be used. In places with high humidity and rainfall, PPC is preferred as it has moisture, alkali and chemical resting properties.
3. Load Requirements- Depending upon the type of construction, the soil is tested and cement chosen. Commercial construction would require cement that has increased load-bearing capacity such as OPC 53 grade due to its early strength property and PSC for its resistance against chloride and sulphate.
Takeaway
Every cement type is designed to meet different structural demands- whether it is a residential project or a commercial one, whether it is the foundation or the structure, and whether it is a dry area or a humid one. Picking cement requires a little bit of research and a whole lot of expert advice. Cement is the backbone of your project and should never be compromised.

FAQs
1. What is the difference between OPC and PPC cement?
PPC is more cost-effective due to added materials such as fly ash, while OPC requires high-energy processing. OPC is made with clinker and some amount of gypsum, whereas PPC is made by grinding fly ash, clay and limestone.
2. Can one type of cement be used in one type of construction?
Ideally no. Though OPC is preferred in residential construction, PPC and PSC would also be required for different areas of the residential structure.
3. What does it mean when we say OPC 33-grade, 43-grade, 53-grade?
OPC grading is done based on the compressive strength the cement achieves after setting for 28 days and its fineness.
