Keeping cement safe is primarily about protecting it from moisture to prevent premature setting and degradation. Based on the provided references, safe storage involves creating a controlled, dry environment.
Key Steps for Safe Cement Storage
To ensure cement remains safe and usable, follow these critical storage guidelines:
- Maintain a Dry Environment: Store cement in a dry, leak-proof, and moisture-proof environment. Any exposure to water or high humidity can cause the cement to hydrate, leading to lump formation and reduced strength.
- Seal the Storage Area: Doors and windows must be kept closed in the storage area. This helps prevent external moisture, rain, or humidity from entering and affecting the cement.
- Proper Stacking: Bags must be stacked on a wooden plank or on a strong tarpaulin. This creates a barrier between the cement bags and the floor.
- Elevate from the Ground: Ensure bags are stacked at least 6 inches above the ground. This elevation prevents moisture from the ground from seeping into the bags, especially if the floor is damp or prone to condensation.
Why Moisture Protection is Crucial
Cement reacts with water in a process called hydration, which is essential for it to harden when mixed into concrete or mortar. However, this reaction must only occur when you are ready to use the cement. Premature exposure to moisture during storage triggers this reaction, causing the cement to harden or form lumps (known as 'air setting' or 'pack-set'). This can significantly reduce its effectiveness or render it unusable. By keeping the storage area dry, sealed, and elevating the bags, you prevent this unwanted hydration, preserving the quality and safety of the cement until it's needed.
Following these simple, yet crucial, steps based on the provided references helps maintain the integrity and performance of the cement.
