After failure of Teton Dam in Idaho on June 5, 1976, the Secretary of the Department of the Interior appointed the Interior Teton Dam Failure Review Group (IRG) to investigate the failure. The Grouting Task Group of the IRG requested that the Bureau of Reclamation initiate a program to test foundation grouts similar to those used during construction of Teton Dam. Grouts were to be (1) made with the same cement, sand, bentonite, and calcium chloride as were used during construction, (2) made using mix proportions representative of grouts used during construction, and (3) mixed and cured as congruently to field conditions as possible. Tests performed on grouts from 66 mixes included: time of setting, unconfined compressive strength, triaxial shear strength, drying shrinkage, erodibility, and permeability. Bleeding characteristics were also analyzed, and a detailed petrographic examination was performed. All grouts exhibited good hydration properties and good physical soundness, adequate strengths, no degradation due to calcium chloride, and low permeability. Areas of future research in neat-cement and sand-cement grouts are also listed.
