Store aggregate at site on a hard dry and level patch of ground
If such a surface is not available then prepare a platform of planks or old corrugated iron sheets, or a floor of bricks, or a thin layer of lean concrete so as to prevent contamination with clay, dust, vegetable and other foreign matter.
Maintain sufficient distance between stacks of fine and coarse aggregates to prevent the material at the edges of the stock piles from getting intermixed.
If possible then construct dividing walls to give each type of aggregate its own compartment.
Stack the fine aggregate in such a place where loss due to effect of wind is minimum.
Stacking of the aggregates should be carried out in regular stacks. The suggested sizes for stacks are as follows.
