 note = {According to theoretical consideration by applying the Smolochowski's equation and the Boltzman and the Einstein equation to coagulation phenomenon of clay particles covered with the absorbed water the following relationship may be used for the thixotropic strength ratio 'R' and time 't' after remolding, if the clay strength is proportional to numbers of points between particles. 
R=A(1-1/Bt+1)+ 1 
where A and B are constants, and R is refined as the ratio between the regained strength due to thixotropic phenomena and the remolded strength of clays. 
Experimental data show that the above equation is approximately effective for montmorillonite clay and kaolinite clay.},
