Proper care and management are required to preserve the quality of cement after manufacture. Even a bad place to store cement can reduce the quality of cement dramatically.
Key points of storing cement in a proper way:
- First of all at site use freshly manufactured cement. From the date of manufacture of cement, use it within 50 days. With time, the strength of cement starts decreasing.
- Cement shall be stored on raised platforms 15 cm above the floor level and 30cm to 60 cm away from the walls under a leak-proof roof.
- Store cement in such a place that is dry and free from moisture.
- Not more than 15 bags of cement shall be stacked vertically in one pile and a maximum width of the pile shall not be more than 3m high.
- Stack cement close to each other so the circulation of air will reduce.
- Cement shall be stored in a way that shall permit the removal and use of cement in the Chronological order of receipt.
- Cement remaining in store for more than 60 days from the date of receipt from the factory shall be subjected to test as indicated in IS 269-1978 and used only if found satisfactory.
- When temporarily stored in the open for use within 48 hours it shall be kept on a platform of planks about 15 to 20 cm above the ground and covered with a tarpaulin.
- Different types of cement or of the same kind but manufactured in a different factory should be stacked and stored separately.
