Abstract

The improvement of the mechanical properties of soils can be attained by the execution of an appropriate injection program. The injection materials that are used for that purpose, called grouts, may be either suspensions of solid particles in water or chemical solutions. Cement suspensions penetrate satisfyingly into coarse sands, whereas chemical solutions penetrate satisfyingly into finer formations, such as fine sands or silty soils. Over the last years, efforts have been made for the evolution of microfine cements suspensions, in order to replace the chemical solutions, which are thought to be toxic and harmful for the environment and the human. In this work, the effect of soil parameters such as uniformity coefficient and degree of saturation on the injectability of cement suspensions is evaluated.
