Tiivistelmä
The purpose of this paper is to study heat current through concrete crush as the crush is considered a possible material for heat storage. The heat current parameter is important for heat storages as it describes how material behaves as temperature changes in its environment. An experimental test is described for obtaining this parameter. Since the resulting data are noisy and have repetitive values, the heat current is evaluated with polynomial fitting.
