Determination of thermal parameters of hardening concrete by means of inverse problem solution

Grzegorz Knor , Michał A. Glinicki , Jan Holnicki-Szulc

Abstract

The paper presents the procedure of determining the thermophysical properties of concrete: heat of hardening, thermal conductivity and specific heat, which is based on point temperature measurements in a cylindrical mold and the numerical solution of the inverse heat transfer problem. The procedure was tested on concrete materials made with high-calcium fly ashes. The obtained results show good agreement with the real values of individual parameters and can be used to determine the temperature field in the object of any complex shape.

Keywords:

calcerous fly ash, heat equation, inverse problem, massive concrete, thermal gradient
