Suggested Guidelines for Storing of Aggregates on Sites:

The below given guidelines are recommended for storing of aggregates on sites:

(a) Aggregates should be stored at site on a hard, dry and leveled patch of ground. In case such patch of ground is not available near the construction site then following arrangements may be made.

(b) Give a platform of planks or of corrugated iron sheets.

(c) Ready a floor of dry bricks or of a thin layer of lean concrete.

(d) Stacks of excellence and coarse aggregates should be kept separate so as to avoid the intermixing of fine and coarse aggregates particularly at the edges.

(e) At the large construction site, it is recommended to give divide walls between the different types of aggregates. This arrangement is shown in Figure 1 where the aggregates of different fractions are separate out by suitable partitioning.

(f) Proper care must be taken within storing the fine aggregates to prevent the loss of finer particles due to wind.

(g) That is recommended to unload the aggregates on the large area surface so as to avoid the pyramid shape of the stack pile in which the coarser aggregates may roll down the sides of the piles thereby disturbing the uniformity of grading from top to bottom.

(h) It is recommended to prevent the dumping of aggregates from greater height or dropping the successive consignments at the same place.

(i) The stacks belonging to all kinds of coarse and fine aggregates and that of cement should be placed as close as possible so as to facilitate the batching and mixing operations.

(j) The size of stacks for various types of aggregates as below :

It is convenient to measure the overall volume of aggregates received on site if stacked in standard shape and sizes.
