Abstract: Some very precious professional test apparatuses have to be needed conventionally for determination of the temperature rising of concrete under the condition of thermal isolation and the surface coefficients of thermal diffusion of concrete.Besides,there are some errors in the test results due to differences between the environmental conditions in laboratory and in site.The authors here have suggested a new concept. With an approach of combination of test and reverse analysis, the thermal characteristic parameters can be obtained simultaneously.The apparatuses needed for the test are simple and the concept could be very easily extended to pratical engineering projects.
