Enhanced durability
Superior resistance to chlorides and sulphates protects structures from chemical attack over their lifetime — particularly important in coastal, marine and chemically aggressive environments.
A Green Pro Certified Cement
Portland Pozzolana Cement (PPC) is a blended cement produced by inter-grinding clinker, gypsum and fly ash sourced from thermal power plants — transforming an industrial by-product into a high-performance construction material.

Why experts choose Portland Pozzolana Cement (PPC)
Low heat of hydration
PPC generates less heat during the curing process than OPC, significantly reducing the risk of thermal cracking in large pours such as raft foundations, retaining walls and dams.
Improved workability
A slightly longer setting time gives site personnel more time to place, compact and finish concrete, an advantage in hot weather conditions where rapid setting can cause handling difficulties.
Environmentally responsible
By incorporating fly ash that would otherwise be treated as industrial waste, Priya Cement PPC conserves natural resources, reduces landfill burden and lowers the construction industry's environmental impact.
Cost-effective
Priya Cement PPC delivers comparable or superior long-term performance to OPC at a more economical cost without compromising on structural integrity or durability.
Long-term strength development
Unlike OPC, which achieves most of its strength within 28 days, PPC continues to gain strength beyond that point resulting in progressively stronger structures over time.
Reduced permeability
Lower porosity means less water and chemical ingress into the structure, protecting reinforcement from corrosion and extending the serviceable life of the building.

Technical specifications
Physical properties
Parameter | What this measures | IS 1489 (Part 1):2015 requirement | Priya Cement test result |
|---|---|---|---|
Fineness — specific surface | How finely the cement is ground. Higher fineness means better reactivity and strength development. | Min. 300 m²/kg | 345 m²/kg |
Initial setting time | How long the cement remains workable after mixing with water. | Min. 30 minutes | 145 minutes |
Final setting time | How long before the cement becomes fully rigid and cannot be disturbed. | Max. 600 minutes | 215 minutes |
Le Chatelier expansion | Measures soundness, specifically whether the cement expands excessively after setting, which can cause cracking. | Max. 10.0 mm | 1.0 mm |
Autoclave expansion | A more stringent test of soundness under high pressure and temperature. | Max. 0.8% | 0.04% |
Drying shrinkage | Measures how much the hardened cement paste contracts as it dries. Lower values indicate reduced risk of surface cracking after curing. | Max. 0.15% | 0.06% |
Compressive strength
Curing period | IS 1489 (Part 1):2015 minimum | Priya Cement test result |
|---|---|---|
3 days | Min. 16 MPa | 24 MPa |
7 days | Min. 22 MPa | 34 MPa |
28 days | Min. 33 MPa | 53 MPa |
Chemical properties
Parameter | What this measures | IS 1489 (Part 1):2015 requirement | Priya Cement |
|---|---|---|---|
Loss on ignition | Measures the proportion of material lost when heated, which indicates cement freshness and quality. | Max. 5.0% | 2.00% |
Insoluble residue | Measures the proportion of fly ash and other pozzolanic materials present. Confirmed as per IS formula. | As per IS formula | 30.36% |
Magnesia | Controls magnesium oxide content, which in excess can cause unsoundness and long-term expansion. | Max. 6.0% | 1.11% |
Chloride content | Measures chloride ions that can accelerate steel reinforcement corrosion. Lower values indicate better protection. | Max. 0.10% | 0.01% |
