Description

Portland Cement Type 1 (Class 525) is the fundamental and most widely used cement in the construction industry. Known as general-purpose cement, it is the standard choice for concrete projects where no specific exposure conditions, such as high sulfate levels or excessive heat of hydration, are a primary concern.

This cement is manufactured to meet strict international standards, ensuring consistent performance and reliability. The “525” classification indicates its high compressive strength, achieving a minimum of 52.5 Megapascals (MPa) after 28 days of curing. This makes it an excellent choice for structural applications requiring robust and durable concrete.

Key Features & Benefits:

• High Early Strength: Develops strength quickly, allowing for faster construction schedules and earlier removal of formwork.
• Excellent Durability: Provides a solid, long-lasting foundation for structures, ensuring resilience against everyday environmental stresses.
• Versatility: Suitable for a vast array of applications, from residential buildings to large-scale infrastructure projects.
• Consistent Quality: Produced under controlled conditions to guarantee uniform performance and reliability in every batch.
• Ideal for Pre-cast Concrete: Its high early strength is particularly beneficial for manufacturing pre-cast concrete elements like blocks, pipes, and panels.

Typical Applications:

• Reinforced Concrete Buildings: Foundations, columns, beams, and slabs.
• Pavements and Sidewalks: Driveways, roads, and walkways.
• Pre-cast Concrete Products: Concrete blocks, bricks, pipes, and septic tanks.
• Mortar for Masonry Work: Used in plastering and bricklaying.
• General Construction Projects: Where no special cement properties are needed.

Portland Cement Type 1 (Class 525) is the trusted, all-round solution for builders, engineers, and contractors seeking a proven material for strong and dependable concrete structures.

Type 1 cement is characterized by its specific compound composition, primarily consisting of tricalcium silicate (C3S) and dicalcium silicate (C2S), which are responsible for its strength development. Class 525 refers to its strength grade, conforming to standards like ASTM C150 (Type I) or EN 197-1 (CEM I 52.5N). It is a normal-setting cement without the specific modifications found in other types (e.g., sulfate resistance in Type V or low heat in Type IV).
