Stone Gravel/Coarse Aggregates - Selection during Construction

Coarse aggregates are normally small pieces of stone which give concrete its strength. The two most commonly used sizes are ¾ inch or 20 mm and ½ inch or 12 mm. At times both are used together in the ratio of 60:40 or even up to 70:30.

While selecting the coarse aggregate, the following points should be kept in mind:
> Coarse aggregate should be solid, in the shape of a cube and free from dirt.
> Any form of contamination should be immediately removed.
> The right proportion of large and small size pieces should be selected. This is to ensure that the space between the large stonechips is filled in by the smaller pieces.
