Abstract: Colloidal nanoparticles were electrokinetically transported into hardened cement paste pores where they underwent chemical reactions resulting in reduced permeability.

Abstract: Electrokinetic nanoparticle treatments have been demonstrated to reduce the permeability of hardened cement paste by orders of magnitude. The origin of this approach stems from the tendency of particles to flocculate and ...

Abstract: The ultrasonic shear-wave reflection coefficient at the interface between a hydrating material and a buffer material was monitored immediately after mixing as a function of time to study setting behavior of self-compacting ...
