Symposium on Grouting: Research in Foundation Grouting with Cement

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. Because 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.
