Development of a sanded expansive salt grout for repository sealing application. Final report
A sanded version of the basic BCT 1-F expansive salt grout was developed by the US Army Engineer Waterways Experiment Station in early 1983 for use in a test by Terra Tek in the Fall of 1983 in Salt Lake City. This grout is known as TT83. Initial laboratory tests showed this mixture had adequate workability, impermeability, strength, and positive volume change. There were problems with flow when this material was batched for the Terra Tek test. Later investigation indicated this was probably due to use of different equipment with lower mixing capacity. Specimens made from this grout show over 0.1% expansion at an age between 56 and 90 days and about 0.3 to 0.4 at 1 year; expansion testing is being continued at 6-month intervals. It was concluded that this mixture is probably satisfactory for use in repository sealing applications in a salt rock horizon.
