There are two kinds of Van der Waals forces: weak London Dispersion Forces and stronger dipole-dipole forces. Introduction WebYODEL is based on van der Waals (vdW) interaction forces to describe the yield stress for flow onset at a critical strain of a few percent, developed for simple non-reactive particulate suspensions. However, due to the high pH and reactivity of cementitious suspensions, their particle interaction forces are much higher than vdW. aggie proverb
