A value of Cu greater than 4 to 6 classifies the soil as well graded. When Cu is less than 4, it is classified as poorly graded or uniformly graded soil. Uniformly graded soil has identical particles with Cu value approximately equal to 1. What is coefficient of concavity?

Websoil and is defined as the ratio of the 60% finer size (D 60) to D 10. that is Cu = D60 D10 (1.13) For curve A in Fig.1.5 the uniformity coefficient is: Cu = 0.57 0.14 = 4.1 which indicates a relatively uniform soil (sometimes referred to as poorly graded). A grain size distribution curve for a soil with a uniformity coefficient larger than WebGradation is an important factor for bearing capacity and for the compaction and is determined from the grain-size distribution curve. Cu=d60/d10 where d60 and d10 are the particle diameters corresponding to values of 60 and 10 percent on the grain-size distribution curve.
