Understanding the thermal and wet physical properties of concrete under different wet conditions is of great significance for studying the temperature control and surface protection measures of concrete dams in different periods. The principle of “normal power planar heat source method” for determining the characteristics of wet and dry heat transfer and damp-heat diffusion of concrete And the method of error transmission analysis of the various parameters that affect the accuracy of the test discussed the need for heat capacity correction of the heating plate so that the entire test can be carried out within the design of the test accuracy to avoid the blindness of the experimental arrangements
