Improving Clay Soils - FineGardening

Clay particles are the smallest of the three, silt are intermediate in size, and sand, the largest. Clay particles, bound end to end and side to side in extensive planes, are stacked in a sandwichlike matrix and held together by electrochemical forces. This platelike stacking of horizontally arranged clay particles results in a large surface area.
