Numerous investigations involving cement grouting of foundations have been conducted since the first large-scale grouting attempt in 1910. Modified cements, mixtures of cement and additives or replacement materials, and proper proportioning of grout ingredients have been developed for various projects as needed. Since the grouting requirements of each job differ, no all-purpose grout or grouting method has been established. However, results of the laboratory and field tests described in this paper show the advantages and disadvantages of cement grout incorporating admixtures, of varying water-cement ratios, and of varying grading and fineness of grout ingredients. In addition, grouting techniques, grouting pressures, and types of equipment utilized in these tests are described. Suggestions for future research in cement grouting from engineers experienced in this field included investigations for 1 controlling the setting time of cement slurries and cement mixtures 2 tracing grout in pervious formations 3 improving mixer and other equipment efficiency 4 grouting fine fissures 5 studying the characteristics of grout incorporating new replacement materials or additives and 6 exploring more thoroughly the foundations to be grouted.
