National 50Kg Ordinary Portland Cement

No, this cement is not recommended for marine or high-sulphate soils. Specialized cements are better suited for such conditions.

Grade 53 OPC offers higher early compressive strength compared to Grades 33 and 43, making it ideal for structures requiring quick setting and high durability.

Yes, National OPC provides resistance against corrosion, making it suitable for long-lasting construction projects.

The primary components include lime, silica, alumina, and iron oxide. These materials contribute to its high strength and binding properties.

The key properties of this cement include a Specific Gravity of 3.15, Fineness of 3400 cm²/g, Initial Setting Time of 65 minutes, Final Setting Time of 275 minutes, and a Compressive Strength of ≥53 MPa at 28 days.

It is widely used for constructing high-rise buildings, roads, bridges, industrial complexes, and other heavy structures due to its superior strength and durability.

The cement is packaged in 50 kg HDPE sack bags, ensuring durability during transportation and storage.

This cement is classified as Grade 53, which signifies high compressive strength, making it suitable for heavy-duty construction like high-rise buildings and bridges.

The shelf life of National OPC is typically up to six months if stored properly in a dry environment. It is crucial to keep the cement away from moisture to maintain its quality and effectiveness in construction projects.

When using National OPC, it can be mixed with aggregates like sand and gravel to create concrete or with other materials for specific applications such as grouting. Proper mixing ratios are essential to achieve desired strength and workability.

National OPC is versatile and can be used in various construction applications, including residential buildings, commercial structures, infrastructure projects, and precast concrete products. Its durability makes it ideal for both indoor and outdoor use.

National OPC is typically available in 50 kg bags, making it convenient for transportation and handling on construction sites. This packaging size is standard in the industry for easy use.

National OPC complies with international standards such as ASTM C150 and EN 197-1. These certifications ensure that the cement meets rigorous quality and performance requirements.

National OPC is classified as 42.5 R Strength Class, indicating that it achieves a minimum compressive strength of 42.5 MPa after 28 days of curing. This makes it suitable for both general and high-strength concrete applications.
