ABSTRACT
The pegmatite samples were taken from the North of Algeria. The aggregates used were crushed in the following way: initial blocks subjected to crushing, with a resulting grain size of 0/20 mm.
After subjecting the blocks of rock to the gyratory crusher, the granular fractions selected were ranged in three sizes as follows: 0/6−6/10−10/14. One obtains the samples of test by separation of the total sample of each size range by a corridor divider.
