摘要：

The reinforced concrete foundations of two buildings in the Arctic were severely damaged by thaumasite formation within two years of construction. Repairs to the piers supporting one building were successfully made by jacketing them with steel-encased silica-fume grout. The column foundations and slabs on grade of the other building were repaired using a polymer concrete formulated to cure at low temperature. These repairs were incompetently made and the resulting concrete had inadequate strength and resistance to freeze-thaw action and chemical attack. These foundations were replaced under strict supervision and control with successful results. Both types of repair are described. The quality control procedures and test results are reported.
