ACC offers standard cement types used widely in building, infrastructure, and heavy civil work.
🧱 2. Main Types of ACC Cement
A. Ordinary Portland Cement (OPC)
This is the most commonly used cement type — ideal for structural concrete and RCC. It comes in different grades depending on strength. �
Scribd +1
OPC 33 Grade
- Older grade, less commonly used now.
- Compressive strength ~33 MPa at 28 days. �
Scribd
OPC 43 Grade - Most common general-purpose cement for buildings, plaster, brickwork, RCC etc.
- Designed strength ~43 MPa after 28 days. �
Scribd
OPC 53 Grade - Higher strength for heavy-load structures like high-rise buildings, columns, bridges.
- Designed strength ~53 MPa at 28 days. �

✅ Uses: Foundations, columns, beams, slabs, concrete, masonry, structural work.
B. Portland Pozzolana Cement (PPC)
Blended cement made by adding pozzolanic materials (like fly ash) to OPC. This improves durability. �
Cement Bazaar
PPC does not have standard grades like OPC, but its strength is often considered similar to around OPC 33 grade. �
Accio
Advantages of PPC:
More durable and less permeable than OPC. �
Cement Bazaar
Lower heat of hydration → less cracking in mass pours. �
Cement Bazaar
Better resistance to chemical and sulfate attack. �
Cement Bazaar
✅ Uses:
Long-lasting residential structures, foundations, marine constructions, dams, water tanks.
🧱 3. Other Higher-Level Cement Types (Industry-Wide)
ACC may also supply or align with other cement categories (not limited to their standard OPC/PPC range):
Portland Slag Cement (PSC) – Better chemical resistance and durability. �
ACC Help
Sulphate Resistant Cement (SRC) – For soils/water with high sulphate content. �
ACC Help
These types are common in the Indian market and may be available through ACC or other brands depending on project needs. �

🧱 4. Cement Grades Explained (Strength Meaning)
Grade
Compressive Strength at 28 Days
Ideal Use
33
~33 MPa
Lightweight structures (less common now)
43
~43 MPa
General construction & RCC
53
~53 MPa
Heavy-load and high-strength structures
👉 Higher grade = higher strength and cost.
For most buildings today, 43 and 53 grade OPC are preferred. �

🧱 5. How to Choose ACC Cement for Your Project
🧱 Based on Construction Needs
✔ Residential Houses:
PPC for long-term durability (better against dampness)
OPC 43 for standard concrete work
✔ High-Strength Structures:
OPC 53 (columns, beams, foundations)
✔ Marine/Water Retaining:
PPC or SRC
✔ Mass Concreting (Dams/Large Slabs):
PPC (lower heat), PSC
📦 6. Packaging & Quality Tips
ACC cement is commonly available in 50 kg bags. �
Comaron
Always check the manufacture date and ISI mark.
Fresh cement (used within ~3 months of manufacture) gives better performance.
