Improvement of the properties and mechanical behavior of soils can be carried out in-situ by carrying out an appropriate injection program. Injection is defined as the process of injecting, under pressure, a fluid material to the required depth from the ground surface. The injection material, which is either a suspension of solid granules in water or a solution of chemicals, displaces soil pore water and sets or solidifies in a short time. The selection of the optimal suspension for the needs of a technical project must be the subject of thorough investigation and documentation and is primarily determined by its properties always combined with the specialized requirements of each application. The criteria, which advocate or not in the selection of an optimal suspension, are related to penetration, setting times, developing strength, stability, rheological properties, permeability, permanence, shrinkage, etc. In this work, the effect of the viscosity and more generally of the rheological properties of cement grouts on injectability is studied with the aim of improving soil formations.
