Rheological Properties of Allophane Colloid
There are many volcanic soils containing allophane in the countries of volcanic soil like Italy, Newzealand, and Japan. The most particular rheological property of allophane is thixotropic, and it happens often in earth work that remolding of soil by machine makes difficult conditions to continue work. The shearing strength of allophane soil goes down to a half or more and soil erosion increases when it gets wet or dry excessively. These mechanical properties result from the surface forces between soil particles.
