Title: Dispersing nano- and micro-sized portlandite particulates via electrosteric exclusion at short screening lengths

Abstract

Coulombic repulsion alone is insufficient to mitigate aggregation of suspensions with strong charge screening, while superior interparticle separations are created via steric hindrance when dispersant layer thickness exceeds the Debye length.
