This work reports the design, development and operation of a hot plate device with guard called HD20 Hot Box to evaluate, under steady-state conditions, the transfer of heat by conduction through test tubes with prism-shaped faces. parallel, and indirectly determine the thermal conductivity of construction concretes with different aggregates. For its design, IRAM 11559, IRAM 11549 and IRAM 11601 standards valid in Argentina were applied. The hot box consists of two main units: the heating unit and the cooling unit. The thermal conductivity values obtained with this apparatus agree satisfactorily with the values published in the literature.
