Abstract : Some of the considerations involved in the development of hydraulic cement-based grout mixtures intended for use in the isolation of nuclear waste stored underground are longevity, impermeability, uniformity, ease of placement, and relevance to previously used systems. Work done at the Structures Laboratory of the U.S. Army Engineer Waterways Experiment Station on this subject has indicated that apparently adequate systems can be based on well known ingredients. Information on field testing and long-term testing of these grouts has confirmed this indication. The following conclusions are indicated: (a) Selection of control parameters such as flow time, time of setting, compressive strength, and permeability for a candidate grout mixture should be criteria used in the formulation of a grout mixture. (b) Once quantitative levels of such parameters have been established, the hydraulic cement-based grout system has adequate latitude in its formulation to accommodate these needs. (c) While longevity in nonaggressive environments and compatibility with host rocks is known in general for such systems, data for specific mixtures under specific conditions must be developed. A Standard Practice for Selecting Mixture Proportions for Hydraulic Cement-Based Materials Systems for Repository Sealing is presented as an Appendix. (Author)
