Abstract:
1. A method of relieving or eliminating existing or potential ettringite-caused distress or damage of stabilized soils, subgrade, base, or subbase, the method comprising: introducing and reacting a fluoride ion releasing agent into the stabilized soils, subgrade, base, or subbase at ambient temperature to reduce occupied space of formed ettringite, where introducing and reacting the fluoride ion releasing agent into the stabilized soils, subgrade, base, or subbase at ambient temperature comprises: a. drilling holes into the stabilized soils, subgrade, base, or subbase; b. filling the holes with the fluoride ion releasing agent in solid phase; c. supplying the holes with water to transport the fluoride ion releasing agent in solid phase into the stabilized soils, subgrade, base, or subbase; d. waiting between approximately 12 to 24 hours to mitigate stress and/or distress; and e. sealing the holes.
