A New Measuring and Calculating Method for Concrete Thermal Conductivity with Multipoint

Abstract:

The real thermal parameters always have inevitable influence on the simulation results of the structure thermal field and stress field in the construction of mass concrete. A new measuring and calculation method for concrete thermal conductivity was put forward. Eight or six sensor points measuring method and calculation formula are present, and the latter is the simplification of the former. Comparing the real thermal conductivity with the calculation result by the new method, it can be seen that the thermal conductivity can be obtained within about 6 day’s age at site and with the accurate degree of 98%. The new method will provide an efficient way for the concrete structure researcher and designer.
