Expansive Grout Plug Effects in Restrained Environments
Technology needs to be developed which can assure the safe storage of hazardous waste material in underground cavities. A large portion of this report is devoted to the pressure-versus-restraint relation of the plugging material. This relation can be determined by using steel pipes to provide known restraints on the plugging material as it expands. The pressure-versus-restraint of the expansive material can be determined from pressures obtained from the fluid pressure calibration of the pipes and from later measurements of strains on the pipes due to the presence of the expansive material inside the pipes. It was found that temperatures between 85 F and 110 F will produce optimum expansion of the BCT-1-FF grout. This can vary somewhat with setting time and strength gain of an expansive mixture. This report also contains a section which illustrates how average pressures created by grout bar tests can be correlated with the pressures produced in cylindrical containers. Keywords: Bar expansion; Cylindrical expansion theory; Deterioration; Expansion in pipes; Expansive grout; Finite-element analysis; Hazardous waste storage; Linear expansion; Moisture effects; Restraint; Sealing; Strains and stresses; Temperature effects; Uniform expansion; Volumetric expansion.
