Storing in Silos:

At the large construction sites where a large quantity of cement is required, the cement is preferred to be stored in silos. In silos, the cement can be stored in bulk (i.e. 12-50 tonnes) and that too under the ideal conditions. Silo is typically a welded steel cylindrical container. It is supported on four crossed braced legs and having a discharge outlet at the bottom. Moreover, it can also have some weighing arrangement at the bottom so as to get the required weight of cement in each batch. Cement is supplied in close tankers from the factory and pumped into these silos directly from these tankers. Storing of cement in silos has the following advantages as compared to storing in stacks:

(a) A cost of bulk cement per tonne is less than the bagged cement.

(b) Unloading of cement by pumping arrangement straight within the silos is quite convenient and cheaper.

(c) Smaller precautions are to be observed.

(d) Less site space is needed for any given quantity of cement.

(e) As cement is delivered within the silos from top and extracted from bottom, the cement, that is received first, is always used first.

(f)  The similar silo can be reused for the other construction sites.
