OPC Cement (Type I/II/V)
What Is OPC Cement?
Ordinary Portland Cement (OPC) is the world’s most widely used cement, essential for structural and architectural applications. Produced from high-quality clinker and gypsum, OPC offers excellent compressive strength, rapid setting time, and long-term durability.
Samanar’s OPC Cement is manufactured using advanced milling technology and high-purity raw materials, ensuring stable performance for concrete, mortar, and all general construction needs.
We supply three major types — Type I, Type II, and Type V — each formulated for specific environmental and structural requirements.
Types of OPC Cement
We supply multiple categories depending on application:
OPC Type I – General Purpose Cement
Ideal for most standard construction projects.
Features:
High early strength
Excellent workability
Reliable performance for everyday concrete applications

OPC Type II – Moderate Sulfate Resistance
Designed for projects exposed to mild sulfate environments.
Features:
Lower heat of hydration
Better resistance to chemical attack
Enhanced long-term durability
Common uses: Water structures, retaining walls, general infrastructure
OPC Type V – High Sulfate Resistance (HSR)
Specifically for harsh environments with high sulfate concentrations.
Features:
Maximum resistance to sulfate attack
Suitable for marine, coastal, and wastewater applications
Long service life even in aggressive environments
Common uses: Marine structures, sewer systems, chemical plants.
