Concrete repair at low temperatures

摘要

Repairing cracks in the foundation of a wind turbine will increase the life of the structure. Magna-Crete is a two-part magnesium phosphate material that sets rapidly and has high green strength. It bonds to concrete and other materials. Without a water additive, Magna-Crete may be applied at temperatures as low as -15°F. The company says work time may be 5 to 20 minutes while cure time may be 2 hours.
