Abstract
In this study, we evaluated the heat curing performance of cold-weather concrete using the induction heating technology. Specifically, we studied the effects of the size and shape of steel forms as well as different concrete mixtures on the heat curing performance. The test results showed that increasing the cross-section of concrete reduced the homogeneity of temperature distribution throughout it. This problem can be compensated for by adding more conductive materials in the concrete cross-section. The concrete specimens that were cured using induction heating achieved a satisfactory early age strength even though they were stored in a 0 °C low-temperature chamber. Furthermore, we evaluated the electromagnetic compatibility (EMC) of the induction heating process and the magnetic flux density of 13.9 µT thus obtained satisfied the EMC requirement.
