Trailered Heater Panel System for Heat Treating Internally Sealed Concrete

摘要

Development services were performed for the design and fabrication of equipment for heat treating internally sealed concrete. The corrosive effects of water and chlorides on the reinforcing steel can be retarded by sealing the interstices of the concrete with a paraffin and montan wax mixture. Beads of the sealing mixture are added to the concrete mix, and after cure, the concrete is heated in a controlled manner causing the sealing materials to melt and flow into and close the capillaries of the concrete. Equipment was designed and fabricated to accomplish the heat treating process. Concepts emphasized the use of powered handling equipment to minimize the labor required to transport and emplace the heat treating equipment.
