RADIO FREQUENCY EQUIPMENT FOR HEAT TREATING INTERNALLY SEALED CONCRETE

This report presents the analysis and conceptual design of a radio frequency (RF) heating system for heat treating internally sealed concrete. Design considerations included: control of heating rate and pattern; ease of operation; energy efficiency; and life-cycle costs. Equipment size and maneuvering requirements for large area (2,000 in one section every 8 hours), low rate heating resulted in equipment not being fabricated and tested, however if rapid heating were allowed, RF systems were shown to be practical and energy efficient. This report will be of interest to researchers and operations personnel concerned with portable, high rate heat sources for relatively small areas.
