Description: Technical Report
Abstract: The Structures Laboratory of the US Army Engineer Waterways Experiment Station has conducted research on cement-based composites for the Waste Isolation Pilot Project (WIPP) since 1977 in support of Sandia National Laboratories. Sealing shafts and plugging boreholes for closure of this geologic repository for radioactive wastes will require grouts and concretes. Salt-saturated grouts and concretes bond adequately to the bedded halite host rock. Freshwater mixtures will plug and seal penetrations through nonhalite strata. This report gives reference values for such properties as unconfined compressive strength, static modulus, restrained expansion, and permeability of candiate grouts and concretes. Values tabulated here are not averages but are values that one could reasonably expect to attain with other candiate mixtures of similar composition. They are values that the authors consider reasonable targets for cement-based composites likely to be used in the closure phase of operation of the WIPP or other underground repository.
