The use of very fine cement grouts for injection into fine-to-medium sands has been proposed to circumvent problems associated with the permanence and toxicity of chemical grouts and the inability of ordinary cement grouts to permeate soil formations finer than coarse sand. Τhe rheological properties of a cement suspension grout significantly determine the success of an injection especially in those cases where geometric constraints do not arise from the size relationship between soil voids and suspension solids. For this reason, it is considered necessary to determine the rheological characteristics of the suspensions during the design phase of an injection program, so as to select the optimal suspensions on a case-by-case basis. In general, determining the rheological behavior of a cement suspension is not an easy task as there are many factors that intervene in it and have opposite effects. In this paper information is given regarding the effect of these factors on the rheological behavior of cement suspensions. In the present paper, reference is made to the properties of cement suspensions and how they change due to the combined use of these materials. At the same time, value ranges that these properties take are given - where possible - with data obtained from the literature review carried out.
