effect of RH% and temperature to cement
(OP)
i only want to know, what is the effect of temperature and RH% to the cement, so that we can make a suitable design for our cement warehouse?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: effect of RH% and temperature to cement
If the cement is in silos it would be dry, but it will probably be cycles often enough.
If the cement is pure Portland cement in bags, in most cases, the packaging should provide 30 days under normal atmospheric conditions if it is not subjected to exterior moisture (as in rain). Rarely, would there be a situation where cement would be stored that long. Bulk cement is usually bagged with a short delay to allow flexibility of use and the high cost of inventory.

in addition during dry season we will open the door to let the fresh air to enter the warehouse with the help of the exhaust fan 1500 cu.m/min capacity to circulate inside the warehouse to remove the excess heat, but during rainy season we will shut down the door and the exhaust fan to avoid moisture to enter the warehouse.

No matter what your created conditions are, you still have to have openings to get the cement in and out and provide proper ventilation
Cement companies do not try to store packaged products any length of time because of inefficiencies created and the long experience. It is usually preferred to store it in steel silos after grinding and sell it in bulk or packaged since packaging can be a short turn-around and keep the package inventory at a reasonable level. Cement bags can have hard corners due to the pressure due to the compression and and any possible moisture are compounded. - No matter what the cause, the ultimate user will complain because the product cannot be mixed/used properly.
The variable conditions, lack of an average storage time and normal packaging problems make an accurate answer unrealistic.
