If: $C_u>6C_{u}1\mathrm{.}0$ and $C_u>6,$ the sample $is$ well graded, otherwise, the sample $is$ poorly graded.

$If$ the sample $is$ poorly graded and $C_{u}is$ less than $or$ equal $to2\mathrm{.}0,$ the sample $is$ uniform.

$Is$ the sample well graded $or$ poorly graded?

$If$ the sample $is$ poorly graded, $isit$ uniform?

Fines: Low Dry Strength

Low Toughness
