Abstract

In addition to particle size, the ability and ease with which cement-based grouts permeate cohesionless soil and fractured rock in grouting applications is governed largely by the viscosity and yield stress of the grout. These rheological characteristics, in turn, are strongly influenced by the evolving early age morphology of the cement grouts due to hydration and the chemical reactions that occur when cement particles come in contact with water. Reported here are the results of a laboratory study undertaken (a) to document by means of environmental scanning electron microscopy the evolution of these early age (first hour after mixing) microstructural formations in microfine cement grout and (b) to correlate the observed morphology changes with measured values of the theological properties during this period. Changes in both the theological characteristics and the morphology of microfine cement grouts are dependent on the cement type, the particle concentration, and additives.
