Electric Heating of Concrete in Winter Construction
Appears on pages(s):
Describes an electrical method of heating concrete in cold weather which has been used in about 80 structures in northern Japan. The structures ranged from simple piers for wooden buildings to abutments and piers 82 ft high. The system, employing a network of electrodes, is applicable to plain or reinforced concrete. The cost of curing by this method varies from 7 to 10 percent of construction cost for plain concrete to 10 to 15 percent for reinforced concrete.
