Q1:

The coefficient of curvature is defined

A

B

C

D

ANS:C -

It is a relation between D30, D10 and D60 particles. And CC is used to find the shape of the particles. The coefficient of curvature is the ratio (D30)2/(D10 * D60), where D60, D30, and D10 are the particle diameters corresponding to 60, 30 and 10% fine on the cumulative particle size distribution curve, respectively.
