⚙️ Key Technical Features of Bojnourd Type 2 Cement

✅ High Compressive Strength
400–600 kg/cm² at 28 days
Suitable for heavy structural applications, docks, and wet foundations

✅ Rapid Hardening
Initial setting time: 130–150 minutes
Speeds up construction and reduces formwork removal time

✅ Moderate Sulfate Resistance (MSR)
An ideal option for projects in semi-humid regions with normal sulfate levels

✅ High Fineness (up to 3880 cm²/g Blaine)
Improves mortar workability and adhesion to aggregates

✅ Controlled Heat of Hydration
Suitable for mass concrete pouring with reduced risk of thermal cracks

🧪 Chemical and Mineral Composition of Bojnourd Type 2 Cement

• C3S (Tricalcium Silicate): up to 64% → Provides early strength
• C2S (Dicalcium Silicate): ~19% → Ensures long-term strength
• Alkalies: <0.8% → Reduces risk of alkali-aggregate reaction
• SO₃: 2.4–2.6% → Controls expansion and enhances durability
• MgO: ~1.9% → Within safe limits to prevent delayed expansion
