Partikel tanah

Secara umum, klasifikasi tanah berdasarkanukuran butirnya adalah:

• Kerikil (gravel) : > 2mm

• Pasir (sand) : 0,1mm – 2mm

• Lanau (silt) : 0,01mm – 0,1mm

• Lempung (clay) : < 0,01mm

Catatan:Cu = 1 Uniform, butiran tanah seragam satu ukuran. (dalam keadaan variasi butiran tanah ekstrim lebar, nilai Cu bisa mencapai 30)Well graded bila :cu = 1-3 dan Cu > 4 (untuk pasir)cu = 1-3, dan Cu > 6 (untuk gravel)
