dc.descriptionAbstract: A sanded version of expansive BCT 1-FF nonsalt grout was developed for use in the 1984 Terra Tek test in Salt Lake City, Utah. For that reason this grout is also known as TT84. Ability to maintain workability (flow) over a 2-hr time period was required in addition to adequate strength, adequate expansion, and low permeability of the hardened material. Laboratory testing also included sealing and exposure to elevated temperature as variables for expansion testing; permeability testing of a combined grout-anhydrite specimen to evaluate this contact surface was also done. Since the test specimen did not perform as well as expected in the Terra Tek test, a fragment of that grout was also examined in the laboratory. All test data generated at WES were satisfactory for this grout. Concern was raised about whether in field use the compressed wall rock will elastically deform so as to accommodate slight contraction of the expansion grout mixture that will probably occur due to cooling after the rise in temperature due to heat of hydration or shrinkage due to drying or both in an actual field installation. It was recommended that periodic monitoring for expansion be continued and should be started to follow changes, if any, in phase composition and microstructure of the grout with time.-
