Abstract

Reported herein are the results of an experimental investigation to evaluate the behavior of dilute microfine cement suspensions and their ability to be injected into fine sands, the latter of which is treated as a process of deep bed filtration. Nine different porous media with D10 ranging from 0.3 to 0.045 mm are described in terms of their specific surface, hydraulic radius, and intrinsic permeability. The viscosity, sedimentation rate, and flocculation characteristics of suspensions of a microfine cement with a water:cement ratio of 2 or higher were determined. Then, the injectability of these suspensions into the selected porous media was evaluated, and microscopic observations were utilized to study the patterns of cement particle deposition in the porous media and the hydration process of the cement pastes. The pattern of suspended particle removal was found to fit a Chi-square probability distribution function.
