Upon your site experience, What is the maximum storage time for cement in site?
This really depends upon the type of cement and the conditions under which it is stored. At 20oC there should not be a problem so long as the relative humidity is maintained below 60%. Above this then there will be prehydration of the cement. This will lengthen the setting time and reduce strength development. If the relative humidity approaches 80% then the silicates in the cement will start to prehydrate and the loss in strength could well be ~30%.
At higher temperatures then it is likely that the effects will be more pronounced.

If the correct storage procedures are followed, the storage period should not exceed six months. If so, the cement must be checked to ensure its validity before use.
all types of cement can store 3 to 5 months in closed rooms without a bit of moisture
