50kg Cement
High-quality, versatile cement for construction and general-purpose applications
Product Overview
Cement is a fine, gray powder that is a key ingredient in concrete, mortar, and other construction applications. Packaged in 50kg bags, it provides a consistent and reliable option for residential, commercial, and industrial building projects. Cement is typically composed of limestone, clay, and other materials that are ground and heated to create a binding agent with high compressive strength.
Key Properties
- Material Composition: A mixture of limestone, clay, and minerals (primarily calcium silicates).
- Color: Gray.
- Particle Size: Fine powder, typically under 45 microns.
- Shelf Life: Approximately 6 months if stored in a dry, cool place.
Technical Specifications
- Compressive Strength: Achieves strength levels based on class, commonly 32.5N, 42.5N, or 52.5N after 28 days.
-
Setting Time:
- Initial Set: Typically within 1-2 hours.
- Final Set: Reaches full set within 6-10 hours.
- Fineness: Usually between 300-500 m²/kg (Blaine fineness), impacting the rate of hydration and strength gain.
- Bulk Density: Approx. 1,200-1,400 kg/m³.
- pH: Alkaline, with a pH level around 12-13 when mixed with water.
Applications
- Concrete Production: Ideal for concrete mixes used in foundations, slabs, and columns.
- Mortar: Used in masonry for binding bricks, blocks, and tiles.
- Plastering and Rendering: Provides a smooth, durable surface for walls and ceilings.
- Floor Screeding: Used in floor screeds to level and finish floors.
- DIY Projects: Suitable for smaller projects like posts, garden features, and pathways.
Advantages
- High Compressive Strength: Suitable for load-bearing structures and high-stress applications.
- Versatility: Used across various applications, from masonry to flooring and decorative features.
- Consistency: Manufactured under strict quality controls, ensuring reliable performance.
- Availability: Packaged in 50kg bags for easy handling, suitable for both large and small projects.
Limitations
- Shelf Life: Loses strength over time if exposed to moisture; must be stored properly.
- Handling Caution: Alkaline nature requires protective gear to avoid skin and eye irritation.
- Setting Constraints: Proper curing is essential to achieve full strength, as improper curing can lead to reduced durability and cracking.
Storage Recommendations
- Store in a dry area, off the ground, and away from moisture.
- Bags should be stacked safely and not more than ten bags high.
- Use within the recommended period to maintain optimal strength and quality.
