In case of fine aggregate, if we use the same size of particles, lets say 1.0 mm, then there may be some voids as shown in the poorly graded case. So to fill those voids, you need particles of lesser size than 1.0 mm. Let us take 0.5 mm. Again this bonding forms voids of less than 0.5 mm. So to reduce those voids you need particles of lesser size.
