Storing in Stacks:
Cement is, generally, supplied in 50-kg bags, which are required to be stored in dry and damp free environment so as to prevent the air setting. At the work site, these bags can be stored in a building or shed which should be dry, leak-proof and moisture-proof to the best possible extent. It should have minimum numbers of windows and close-fitting doors, that should be kept closed as far as probable. For storing the cement bags in stacks following precautions must be observed:
(a) Do not stack the cement bags directly on the floors. They shall be placed on the dry wooden planks, which should be clear above the floor by 150 mm to 200 mm.
(b) Maintain a minimum alround space of 450 mm between the bags and the external walls. Also, maintain enough alround space between two adjacent stacks for proper movement.
(c) Place a cement bags within a stack close together so as to minimize the air circulation.
(d) Restrict a height of a stack to maximum 15 bags so as to prevent the possibility of lumping up under pressure.
(e) Restrict a width of a stack preferably to 4 bags or 3 or meter or whichever is less.
(f) For the height of a stack more than that of 8 bags, place the bags lengthwise and widthwise in alternate layer so as to minimise the danger of toppling over.
(g) Stack a cement bags within a manner so as to facilitate their removal in the order in which they are received.
(h) For storing a cement bags for longer period or during monsoon, cover each stack with waterproof sheathing.
(i) Store various kinds of cement in different stacks.
(j) Number of bags located on site should be such so as to be consumed on the same day.
