Reduction in Cement Strength Due To Storage
1. Due to absorption of moisture by cement during storage, cement retards in hardening and reduces the strength. 2. It is okay for cement to absorb up to 1.2% moisture as this level of moisture is acceptable but if absorption exceeds 5%, the cement is destroyed for all practical purposes. 3. Different types of cements should not be mixed while using them for constructional purposes.
So in all reason for safety it is most important to have a clearly marked cement bag with all details of manufacturing including date of manufacturing, expiry and batch number.
