The improvement of properties along with the mechanical behavior of soil formations is often achieved by the execution of an injection program that is designed accordingly and adapted to the needs of the specific technical project. The grouts used to make permeation grouting are mainly suspensions and chemical solutions. The suspensions penetrate well into soils with granulometry up to coarse sand. The injectability and penetrability of cement-based slurries are significantly affected by factors such as cement granulometry, water-to-cement ratio, grain size and degree of sand compaction, type and dosage of slurry admixtures, mixing process and the impregnation pressure. The objective of this work was to evaluate the effect of the mixing process and the impregnation pressure on the injectability of cement suspensions.
