The clay or mixture of clays should preferably conform to the following mechanical composition % by Weight.
Grain size analysis shall be done in accordance With the method given in IS 2720 (Part 4 ) 1986
Clay 18-22 %
Silt 40-45 %
Sand 30-40 %
The total content of clay and silt be preferably not less than 60 percent by weight.
In case of soils which are more sandy or clayey than the limits specified above, the same should be blended with more plastic clay or nonplastic materials as the case may be so as to bring the mechanical composition within the above specified limits.
