Research and development of installation for microwave heating of concrete before pouring into molds

The article deals with the possibility of using microwave energy to heat concrete before pouring into molds. The experimental researches of increase of heavy concrete strength at microwave heating are made. The perspectives of the rapid microwave concrete hardening at 40–60 °C are shown. The possibilities of creating of high-power microwave installations for preheating of concrete mixtures using waveguide chambers are presented. Development of modular installation project for microwave heating of concrete before pouring into molds has been done. One installation module at microwave power 50 kW and plant capacity 10 m³/hour allows to raise the temperature of the concrete by 6 degrees.
